+
+// This SDK is designed to work with clang and specific versions of
+// gcc >= 4.0 with Apple's patch sets
+
+// Compatibility with compilers and environments that don't support compiler
+// feature checking function-like macros.
+
+// The __CONCAT macro is used to concatenate parts of symbol names, e.g.
+// with "#define OLD(foo) __CONCAT(old,foo)", OLD(foo) produces oldfoo.
+// The __CONCAT macro is a bit tricky -- make sure you don't put spaces
+// in between its arguments.  __CONCAT can also concatenate double-quoted
+// strings produced by the __STRING macro, but this only works with ANSI C.
+
+// In non-ANSI C environments, new programs will want ANSI-only C keywords
+// deleted from the program and old programs will want them left alone.
+// When using a compiler other than gcc, programs using the ANSI C keywords
+// const, inline etc. as normal identifiers should define -DNO_ANSI_KEYWORDS.
+// When using "gcc -traditional", we assume that this is the intent; if
+// __GNUC__ is defined but __STDC__ is not, we leave the new keywords alone.
+
+// __unused denotes variables and functions that may not be used, preventing
+// the compiler from warning about it if not used.
+
+// __used forces variables and functions to be included even if it appears
+// to the compiler that they are not used (and would thust be discarded).
+
+// __cold marks code used for debugging or that is rarely taken
+// and tells the compiler to optimize for size and outline code.
+
+// __deprecated causes the compiler to produce a warning when encountering
+// code using the deprecated functionality.
+// __deprecated_msg() does the same, and compilers that support it will print
+// a message along with the deprecation warning.
+// This may require turning on such warning with the -Wdeprecated flag.
+// __deprecated_enum_msg() should be used on enums, and compilers that support
+// it will print the deprecation warning.
+// __kpi_deprecated() specifically indicates deprecation of kernel programming
+// interfaces in Kernel.framework used by KEXTs.
+
+// __unavailable causes the compiler to error out when encountering
+// code using the tagged function of variable.
+
+// Delete pseudo-keywords wherever they are not available or needed.
+
+// We use `__restrict' as a way to define the `restrict' type qualifier
+// without disturbing older software that is unaware of C99 keywords.
+
+// Compatibility with compilers and environments that don't support the
+// nullability feature.
+
+// __disable_tail_calls causes the compiler to not perform tail call
+// optimization inside the marked function.
+
+// __not_tail_called causes the compiler to prevent tail call optimization
+// on statically bound calls to the function.  It has no effect on indirect
+// calls.  Virtual functions, objective-c methods, and functions marked as
+// "always_inline" cannot be marked as __not_tail_called.
+
+// __result_use_check warns callers of a function that not using the function
+// return value is a bug, i.e. dismissing malloc() return value results in a
+// memory leak.
+
+// __swift_unavailable causes the compiler to mark a symbol as specifically
+// unavailable in Swift, regardless of any other availability in C.
+
+// __abortlike is the attribute to put on functions like abort() that are
+// typically used to mark assertions. These optimize the codegen
+// for outlining while still maintaining debugability.
+
+// Declaring inline functions within headers is error-prone due to differences
+// across various versions of the C language and extensions.  __header_inline
+// can be used to declare inline functions within system headers.  In cases
+// where you want to force inlining instead of letting the compiler make
+// the decision, you can use __header_always_inline.
+//
+// Be aware that using inline for functions which compilers may also provide
+// builtins can behave differently under various compilers.  If you intend to
+// provide an inline version of such a function, you may want to use a macro
+// instead.
+//
+// The check for !__GNUC__ || __clang__ is because gcc doesn't correctly
+// support c99 inline in some cases:
+// http://gcc.gnu.org/bugzilla/show_bug.cgi?id=55965
+
+// Compiler-dependent macros that bracket portions of code where the
+// "-Wunreachable-code" warning should be ignored. Please use sparingly.
+
+// Compiler-dependent macros to declare that functions take printf-like
+// or scanf-like arguments.  They are null except for versions of gcc
+// that are known to support the features properly.  Functions declared
+// with these attributes will cause compilation warnings if there is a
+// mismatch between the format string and subsequent function parameter
+// types.
+
+// Source compatibility only, ID string not emitted in object file
+
+// __alloc_size can be used to label function arguments that represent the
+// size of memory that the function allocates and returns. The one-argument
+// form labels a single argument that gives the allocation size (where the
+// arguments are numbered from 1):
+//
+// void	*malloc(size_t __size) __alloc_size(1);
+//
+// The two-argument form handles the case where the size is calculated as the
+// product of two arguments:
+//
+// void	*calloc(size_t __count, size_t __size) __alloc_size(1,2);
+
+// COMPILATION ENVIRONMENTS -- see compat(5) for additional detail
+//
+// DEFAULT	By default newly complied code will get POSIX APIs plus
+//		Apple API extensions in scope.
+//
+//		Most users will use this compilation environment to avoid
+//		behavioral differences between 32 and 64 bit code.
+//
+// LEGACY	Defining _NONSTD_SOURCE will get pre-POSIX APIs plus Apple
+//		API extensions in scope.
+//
+//		This is generally equivalent to the Tiger release compilation
+//		environment, except that it cannot be applied to 64 bit code;
+//		its use is discouraged.
+//
+//		We expect this environment to be deprecated in the future.
+//
+// STRICT	Defining _POSIX_C_SOURCE or _XOPEN_SOURCE restricts the
+//		available APIs to exactly the set of APIs defined by the
+//		corresponding standard, based on the value defined.
+//
+//		A correct, portable definition for _POSIX_C_SOURCE is 200112L.
+//		A correct, portable definition for _XOPEN_SOURCE is 600L.
+//
+//		Apple API extensions are not visible in this environment,
+//		which can cause Apple specific code to fail to compile,
+//		or behave incorrectly if prototypes are not in scope or
+//		warnings about missing prototypes are not enabled or ignored.
+//
+// In any compilation environment, for correct symbol resolution to occur,
+// function prototypes must be in scope.  It is recommended that all Apple
+// tools users add either the "-Wall" or "-Wimplicit-function-declaration"
+// compiler flags to their projects to be warned when a function is being
+// used without a prototype in scope.
+
+// These settings are particular to each product.
+// Platform: MacOSX
+// #undef __DARWIN_ONLY_UNIX_CONFORMANCE (automatically set for 64-bit)
+
+// The __DARWIN_ALIAS macros are used to do symbol renaming; they allow
+// legacy code to use the old symbol, thus maintaining binary compatibility
+// while new code can use a standards compliant version of the same function.
+//
+// __DARWIN_ALIAS is used by itself if the function signature has not
+// changed, it is used along with a #ifdef check for __DARWIN_UNIX03
+// if the signature has changed.  Because the __LP64__ environment
+// only supports UNIX03 semantics it causes __DARWIN_UNIX03 to be
+// defined, but causes __DARWIN_ALIAS to do no symbol mangling.
+//
+// As a special case, when XCode is used to target a specific version of the
+// OS, the manifest constant __ENVIRONMENT_MAC_OS_X_VERSION_MIN_REQUIRED__
+// will be defined by the compiler, with the digits representing major version
+// time 100 + minor version times 10 (e.g. 10.5 := 1050).  If we are targeting
+// pre-10.5, and it is the default compilation environment, revert the
+// compilation environment to pre-__DARWIN_UNIX03.

+// POSIX.1 requires that the macros we test be defined before any standard

+//  _POSIX_C_SOURCE == 1L		1003.1-1990

+//  _POSIX_C_SOURCE == 200809L		1003.1-2008
+//
+// In addition, the X/Open Portability Guide, which is now the Single UNIX
+// Specification, defines a feature-test macro which indicates the version of

+//  Public darwin-specific feature macros
+//
+
+// _DARWIN_FEATURE_64_BIT_INODE indicates that the ino_t type is 64-bit, and
+// structures modified for 64-bit inodes (like struct stat) will be used.
+
+// _DARWIN_FEATURE_64_ONLY_BIT_INODE indicates that the ino_t type may only
+// be 64-bit; there is no support for 32-bit ino_t when this macro is defined
+// (and non-zero).  There is no struct stat64 either, as the regular
+// struct stat will already be the 64-bit version.
+
+// _DARWIN_FEATURE_ONLY_VERS_1050 indicates that only those APIs updated
+// in 10.5 exists; no pre-10.5 variants are available.
+
+// _DARWIN_FEATURE_ONLY_UNIX_CONFORMANCE indicates only UNIX conforming API
+// are available (the legacy BSD APIs are not available)
+
+// _DARWIN_FEATURE_UNIX_CONFORMANCE indicates whether UNIX conformance is on,
+// and specifies the conformance level (3 is SUSv3)
+
+// This macro casts away the qualifier from the variable
+//
+// Note: use at your own risk, removing qualifiers can result in
+// catastrophic run-time failures.
+
+// __XNU_PRIVATE_EXTERN is a linkage decoration indicating that a symbol can be
+// used from other compilation units, but not other libraries or executables.
+
+// Architecture validation for current SDK
+
+// Similar to OS_ENUM/OS_CLOSED_ENUM/OS_OPTIONS/OS_CLOSED_OPTIONS
+//
+// This provides more advanced type checking on compilers supporting
+// the proper extensions, even in C.

+
+// This SDK is designed to work with clang and specific versions of
+// gcc >= 4.0 with Apple's patch sets
+
+// Compatibility with compilers and environments that don't support compiler
+// feature checking function-like macros.
+
+// The __CONCAT macro is used to concatenate parts of symbol names, e.g.
+// with "#define OLD(foo) __CONCAT(old,foo)", OLD(foo) produces oldfoo.
+// The __CONCAT macro is a bit tricky -- make sure you don't put spaces
+// in between its arguments.  __CONCAT can also concatenate double-quoted
+// strings produced by the __STRING macro, but this only works with ANSI C.
+
+// In non-ANSI C environments, new programs will want ANSI-only C keywords
+// deleted from the program and old programs will want them left alone.
+// When using a compiler other than gcc, programs using the ANSI C keywords
+// const, inline etc. as normal identifiers should define -DNO_ANSI_KEYWORDS.
+// When using "gcc -traditional", we assume that this is the intent; if
+// __GNUC__ is defined but __STDC__ is not, we leave the new keywords alone.
+
+// __pure2 can be used for functions that are only a function of their scalar
+// arguments (meaning they can't dereference pointers).
+//
+// __stateful_pure can be used for functions that have no side effects,
+// but depend on the state of the memory.
+
+// __unused denotes variables and functions that may not be used, preventing
+// the compiler from warning about it if not used.
+
+// __used forces variables and functions to be included even if it appears
+// to the compiler that they are not used (and would thust be discarded).
+
+// __cold marks code used for debugging or that is rarely taken
+// and tells the compiler to optimize for size and outline code.
+
+// __exported denotes symbols that should be exported even when symbols
+// are hidden by default.
+// __exported_push/_exported_pop are pragmas used to delimit a range of
+//  symbols that should be exported even when symbols are hidden by default.
+
+// __deprecated causes the compiler to produce a warning when encountering
+// code using the deprecated functionality.
+// __deprecated_msg() does the same, and compilers that support it will print
+// a message along with the deprecation warning.
+// This may require turning on such warning with the -Wdeprecated flag.
+// __deprecated_enum_msg() should be used on enums, and compilers that support
+// it will print the deprecation warning.
+// __kpi_deprecated() specifically indicates deprecation of kernel programming
+// interfaces in Kernel.framework used by KEXTs.
+
+// __unavailable causes the compiler to error out when encountering
+// code using the tagged function
+
+// Delete pseudo-keywords wherever they are not available or needed.
+
+// We use `__restrict' as a way to define the `restrict' type qualifier
+// without disturbing older software that is unaware of C99 keywords.
+
+// Compatibility with compilers and environments that don't support the
+// nullability feature.
+
+// __disable_tail_calls causes the compiler to not perform tail call
+// optimization inside the marked function.
+
+// __not_tail_called causes the compiler to prevent tail call optimization
+// on statically bound calls to the function.  It has no effect on indirect
+// calls.  Virtual functions, objective-c methods, and functions marked as
+// "always_inline" cannot be marked as __not_tail_called.
+
+// __result_use_check warns callers of a function that not using the function
+// return value is a bug, i.e. dismissing malloc() return value results in a
+// memory leak.
+
+// __swift_unavailable causes the compiler to mark a symbol as specifically
+// unavailable in Swift, regardless of any other availability in C.
+
+// __abortlike is the attribute to put on functions like abort() that are
+// typically used to mark assertions. These optimize the codegen
+// for outlining while still maintaining debugability.
+
+// Declaring inline functions within headers is error-prone due to differences
+// across various versions of the C language and extensions.  __header_inline
+// can be used to declare inline functions within system headers.  In cases
+// where you want to force inlining instead of letting the compiler make
+// the decision, you can use __header_always_inline.
+//
+// Be aware that using inline for functions which compilers may also provide
+// builtins can behave differently under various compilers.  If you intend to
+// provide an inline version of such a function, you may want to use a macro
+// instead.
+//
+// The check for !__GNUC__ || __clang__ is because gcc doesn't correctly
+// support c99 inline in some cases:
+// http://gcc.gnu.org/bugzilla/show_bug.cgi?id=55965
+
+// Compiler-dependent macros that bracket portions of code where the
+// "-Wunreachable-code" warning should be ignored. Please use sparingly.
+
+// Compiler-dependent macros to declare that functions take printf-like
+// or scanf-like arguments.  They are null except for versions of gcc
+// that are known to support the features properly.  Functions declared
+// with these attributes will cause compilation warnings if there is a
+// mismatch between the format string and subsequent function parameter
+// types.
+
+// Source compatibility only, ID string not emitted in object file
+
+// __alloc_size can be used to label function arguments that represent the
+// size of memory that the function allocates and returns. The one-argument
+// form labels a single argument that gives the allocation size (where the
+// arguments are numbered from 1):
+//
+// void	*malloc(size_t __size) __alloc_size(1);
+//
+// The two-argument form handles the case where the size is calculated as the
+// product of two arguments:
+//
+// void	*calloc(size_t __count, size_t __size) __alloc_size(1,2);
+
+// COMPILATION ENVIRONMENTS -- see compat(5) for additional detail
+//
+// DEFAULT	By default newly complied code will get POSIX APIs plus
+//		Apple API extensions in scope.
+//
+//		Most users will use this compilation environment to avoid
+//		behavioral differences between 32 and 64 bit code.
+//
+// LEGACY	Defining _NONSTD_SOURCE will get pre-POSIX APIs plus Apple
+//		API extensions in scope.
+//
+//		This is generally equivalent to the Tiger release compilation
+//		environment, except that it cannot be applied to 64 bit code;
+//		its use is discouraged.
+//
+//		We expect this environment to be deprecated in the future.
+//
+// STRICT	Defining _POSIX_C_SOURCE or _XOPEN_SOURCE restricts the
+//		available APIs to exactly the set of APIs defined by the
+//		corresponding standard, based on the value defined.
+//
+//		A correct, portable definition for _POSIX_C_SOURCE is 200112L.
+//		A correct, portable definition for _XOPEN_SOURCE is 600L.
+//
+//		Apple API extensions are not visible in this environment,
+//		which can cause Apple specific code to fail to compile,
+//		or behave incorrectly if prototypes are not in scope or
+//		warnings about missing prototypes are not enabled or ignored.
+//
+// In any compilation environment, for correct symbol resolution to occur,
+// function prototypes must be in scope.  It is recommended that all Apple
+// tools users add either the "-Wall" or "-Wimplicit-function-declaration"
+// compiler flags to their projects to be warned when a function is being
+// used without a prototype in scope.
+
+// These settings are particular to each product.
+// Platform: MacOSX
+
+// The __DARWIN_ALIAS macros are used to do symbol renaming; they allow
+// legacy code to use the old symbol, thus maintaining binary compatibility
+// while new code can use a standards compliant version of the same function.
+//
+// __DARWIN_ALIAS is used by itself if the function signature has not
+// changed, it is used along with a #ifdef check for __DARWIN_UNIX03
+// if the signature has changed.  Because the __LP64__ environment
+// only supports UNIX03 semantics it causes __DARWIN_UNIX03 to be
+// defined, but causes __DARWIN_ALIAS to do no symbol mangling.
+//
+// As a special case, when XCode is used to target a specific version of the
+// OS, the manifest constant __ENVIRONMENT_MAC_OS_X_VERSION_MIN_REQUIRED__
+// will be defined by the compiler, with the digits representing major version
+// time 100 + minor version times 10 (e.g. 10.5 := 1050).  If we are targeting
+// pre-10.5, and it is the default compilation environment, revert the
+// compilation environment to pre-__DARWIN_UNIX03.

+//  Public darwin-specific feature macros
+//
+
+// _DARWIN_FEATURE_64_BIT_INODE indicates that the ino_t type is 64-bit, and
+// structures modified for 64-bit inodes (like struct stat) will be used.
+
+// _DARWIN_FEATURE_64_ONLY_BIT_INODE indicates that the ino_t type may only
+// be 64-bit; there is no support for 32-bit ino_t when this macro is defined
+// (and non-zero).  There is no struct stat64 either, as the regular
+// struct stat will already be the 64-bit version.
+
+// _DARWIN_FEATURE_ONLY_VERS_1050 indicates that only those APIs updated
+// in 10.5 exists; no pre-10.5 variants are available.
+
+// _DARWIN_FEATURE_ONLY_UNIX_CONFORMANCE indicates only UNIX conforming API
+// are available (the legacy BSD APIs are not available)
+
+// _DARWIN_FEATURE_UNIX_CONFORMANCE indicates whether UNIX conformance is on,
+// and specifies the conformance level (3 is SUSv3)
+
+// This macro casts away the qualifier from the variable
+//
+// Note: use at your own risk, removing qualifiers can result in
+// catastrophic run-time failures.
+
+// __XNU_PRIVATE_EXTERN is a linkage decoration indicating that a symbol can be
+// used from other compilation units, but not other libraries or executables.
+
+// We intentionally define to nothing pointer attributes which do not have an
+// impact on the ABI. __indexable and __bidi_indexable are not defined because
+// of the ABI incompatibility that makes the diagnostic preferable.
+
+// Similarly, we intentionally define to nothing the
+// __ptrcheck_abi_assume_single and __ptrcheck_abi_assume_unsafe_indexable
+// macros because they do not lead to an ABI incompatibility. However, we do not
+// define the indexable and unsafe_indexable ones because the diagnostic is
+// better than the silent ABI break.
+
+// __unsafe_forge intrinsics are defined as regular C casts.
+
+// decay operates normally; attribute is meaningless without pointer checks.
+
+// Architecture validation for current SDK
+
+// Similar to OS_ENUM/OS_CLOSED_ENUM/OS_OPTIONS/OS_CLOSED_OPTIONS
+//
+// This provides more advanced type checking on compilers supporting
+// the proper extensions, even in C.

+
+// Testing against Clang-specific extensions.
+
+// This code has been put in place to help reduce the addition of
+// compiler specific defines in FreeBSD code.  It helps to aid in
+// having a compiler-agnostic source tree.
+
+// Compiler memory barriers, specific to gcc and clang.
+
+// XXX: if __GNUC__ >= 2: not tested everywhere originally, where replaced
+
+// Macro to test if we're using a specific version of gcc or later.
+
+// The __CONCAT macro is used to concatenate parts of symbol names, e.g.
+// with "#define OLD(foo) __CONCAT(old,foo)", OLD(foo) produces oldfoo.
+// The __CONCAT macro is a bit tricky to use if it must work in non-ANSI
+// mode -- there must be no spaces between its arguments, and for nested
+// __CONCAT's, all the __CONCAT's must be at the left.  __CONCAT can also
+// concatenate double-quoted strings produced by the __STRING macro, but
+// this only works with ANSI C.
+//
+// __XSTRING is like __STRING, but it expands any macros in its argument
+// first.  It is only available with ANSI C.
+
+// Compiler-dependent macros to help declare dead (non-returning) and
+// pure (no side effects) functions, and unused variables.  They are
+// null except for versions of gcc that are known to support the features
+// properly (old versions of gcc-2 supported the dead and pure features
+// in a different (wrong) way).  If we do not provide an implementation
+// for a given compiler, let the compile fail if it is told to use
+// a feature that we cannot live without.
+
+// Keywords added in C11.
+
+// Emulation of C11 _Generic().  Unlike the previously defined C11
+// keywords, it is not possible to implement this using exactly the same
+// syntax.  Therefore implement something similar under the name
+// __generic().  Unlike _Generic(), this macro can only distinguish
+// between a single type, so it requires nested invocations to
+// distinguish multiple cases.
+
+// C99 Static array indices in function parameter declarations.  Syntax such as:
+// void bar(int myArray[static 10]);
+// is allowed in C99 but not in C++.  Define __min_size appropriately so
+// headers using it can be compiled in either language.  Use like this:
+// void bar(int myArray[__min_size(10)]);
+
+// XXX: should use `#if __STDC_VERSION__ < 199901'.
+
+// C++11 exposes a load of C99 stuff
+
+// GCC 2.95 provides `__restrict' as an extension to C90 to support the
+// C99-specific `restrict' type qualifier.  We happen to use `__restrict' as
+// a way to define the `restrict' type qualifier without disturbing older
+// software that is unaware of C99 keywords.
+
+// GNU C version 2.96 adds explicit branch prediction so that
+// the CPU back-end can hint the processor and also so that
+// code blocks can be reordered such that the predicted path
+// sees a more linear flow, thus improving cache behavior, etc.
+//
+// The following two macros provide us with a way to utilize this
+// compiler feature.  Use __predict_true() if you expect the expression
+// to evaluate to true, and __predict_false() if you expect the
+// expression to evaluate to false.
+//
+// A few notes about usage:
+//
+//	* Generally, __predict_false() error condition checks (unless
+//	  you have some _strong_ reason to do otherwise, in which case
+//	  document it), and/or __predict_true() `no-error' condition
+//	  checks, assuming you want to optimize for the no-error case.
+//
+//	* Other than that, if you don't know the likelihood of a test
+//	  succeeding from empirical or other `hard' evidence, don't
+//	  make predictions.
+//
+//	* These are meant to be used in places that are run `a lot'.
+//	  It is wasteful to make predictions in code that is run
+//	  seldomly (e.g. at subsystem initialization time) as the
+//	  basic block reordering that this affects can often generate
+//	  larger code.
+
+// We define this here since <stddef.h>, <sys/queue.h>, and <sys/types.h>
+// require it.
+
+// Given the pointer x to the member m of the struct s, return
+// a pointer to the containing structure.  When using GCC, we first
+// assign pointer x to a local variable, to check that its type is
+// compatible with member m.
+
+// Compiler-dependent macros to declare that functions take printf-like
+// or scanf-like arguments.  They are null except for versions of gcc
+// that are known to support the features properly (old versions of gcc-2
+// didn't permit keeping the keywords out of the application namespace).
+
+// Compiler-dependent macros that rely on FreeBSD-specific extensions.
+
+// Embed the rcs id of a source file in the resulting library.  Note that in
+// more recent ELF binutils, we use .ident allowing the ID to be stripped.
+// Usage:
+//	__FBSDID("$FreeBSD$");
+
+// -
+// The following definitions are an extension of the behavior originally
+// implemented in <sys/_posix.h>, but with a different level of granularity.
+// POSIX.1 requires that the macros we test be defined before any standard
+// header file is included.
+//
+// Here's a quick run-down of the versions:
+//  defined(_POSIX_SOURCE)		1003.1-1988
+//  _POSIX_C_SOURCE == 1		1003.1-1990
+//  _POSIX_C_SOURCE == 2		1003.2-1992 C Language Binding Option
+//  _POSIX_C_SOURCE == 199309		1003.1b-1993
+//  _POSIX_C_SOURCE == 199506		1003.1c-1995, 1003.1i-1995,
+//					and the omnibus ISO/IEC 9945-1: 1996
+//  _POSIX_C_SOURCE == 200112		1003.1-2001
+//  _POSIX_C_SOURCE == 200809		1003.1-2008
+//
+// In addition, the X/Open Portability Guide, which is now the Single UNIX
+// Specification, defines a feature-test macro which indicates the version of
+// that specification, and which subsumes _POSIX_C_SOURCE.
+//
+// Our macros begin with two underscores to avoid namespace screwage.
+
+// Deal with IEEE Std. 1003.1-1990, in which _POSIX_C_SOURCE == 1.
+
+// Deal with IEEE Std. 1003.2-1992, in which _POSIX_C_SOURCE == 2.
+
+// Deal with various X/Open Portability Guides and Single UNIX Spec.
+
+// Deal with all versions of POSIX.  The ordering relative to the tests above is
+// important.
+// -
+// Deal with _ANSI_SOURCE:
+// If it is defined, and no other compilation environment is explicitly
+// requested, then define our internal feature-test macros to zero.  This
+// makes no difference to the preprocessor (undefined symbols in preprocessing
+// expressions are defined to have value zero), but makes it more convenient for
+// a test program to print out the values.
+//
+// If a program mistakenly defines _ANSI_SOURCE and some other macro such as
+// _POSIX_C_SOURCE, we will assume that it wants the broader compilation
+// environment (and in fact we will never get here).
+
+// User override __EXT1_VISIBLE
+
+// Old versions of GCC use non-standard ARM arch symbols; acle-compat.h
+// translates them to __ARM_ARCH and the modern feature symbols defined by ARM.
+
+// Nullability qualifiers: currently only supported by Clang.
+
+// Type Safety Checking
+//
+// Clang provides additional attributes to enable checking type safety
+// properties that cannot be enforced by the C type system.
+
+// Lock annotations.
+//
+// Clang provides support for doing basic thread-safety tests at
+// compile-time, by marking which locks will/should be held when
+// entering/leaving a functions.
+//
+// Furthermore, it is also possible to annotate variables and structure
+// members to enforce that they are only accessed when certain locks are
+// held.
+
+// Structure implements a lock.
+
+// Function acquires an exclusive or shared lock.
+
+// Function attempts to acquire an exclusive or shared lock.
+
+// Function releases a lock.
+
+// Function asserts that an exclusive or shared lock is held.
+
+// Function requires that an exclusive or shared lock is or is not held.
+
+// Function should not be analyzed.
+
+// Function or variable should not be sanitized, e.g., by AddressSanitizer.
+// GCC has the nosanitize attribute, but as a function attribute only, and
+// warns on use as a variable attribute.
+

+
+// Testing against Clang-specific extensions.
+
+// This code has been put in place to help reduce the addition of
+// compiler specific defines in FreeBSD code.  It helps to aid in
+// having a compiler-agnostic source tree.
+
+// Compiler memory barriers, specific to gcc and clang.
+
+// XXX: if __GNUC__ >= 2: not tested everywhere originally, where replaced
+
+// Macro to test if we're using a specific version of gcc or later.
+
+// The __CONCAT macro is used to concatenate parts of symbol names, e.g.
+// with "#define OLD(foo) __CONCAT(old,foo)", OLD(foo) produces oldfoo.
+// The __CONCAT macro is a bit tricky to use if it must work in non-ANSI
+// mode -- there must be no spaces between its arguments, and for nested
+// __CONCAT's, all the __CONCAT's must be at the left.  __CONCAT can also
+// concatenate double-quoted strings produced by the __STRING macro, but
+// this only works with ANSI C.
+//
+// __XSTRING is like __STRING, but it expands any macros in its argument
+// first.  It is only available with ANSI C.
+
+// Compiler-dependent macros to help declare dead (non-returning) and
+// pure (no side effects) functions, and unused variables.  They are
+// null except for versions of gcc that are known to support the features
+// properly (old versions of gcc-2 supported the dead and pure features
+// in a different (wrong) way).  If we do not provide an implementation
+// for a given compiler, let the compile fail if it is told to use
+// a feature that we cannot live without.
+
+// Keywords added in C11.
+
+// Emulation of C11 _Generic().  Unlike the previously defined C11
+// keywords, it is not possible to implement this using exactly the same
+// syntax.  Therefore implement something similar under the name
+// __generic().  Unlike _Generic(), this macro can only distinguish
+// between a single type, so it requires nested invocations to
+// distinguish multiple cases.
+
+// C99 Static array indices in function parameter declarations.  Syntax such as:
+// void bar(int myArray[static 10]);
+// is allowed in C99 but not in C++.  Define __min_size appropriately so
+// headers using it can be compiled in either language.  Use like this:
+// void bar(int myArray[__min_size(10)]);
+
+// XXX: should use `#if __STDC_VERSION__ < 199901'.
+
+// C++11 exposes a load of C99 stuff
+
+// GCC 2.95 provides `__restrict' as an extension to C90 to support the
+// C99-specific `restrict' type qualifier.  We happen to use `__restrict' as
+// a way to define the `restrict' type qualifier without disturbing older
+// software that is unaware of C99 keywords.
+
+// GNU C version 2.96 adds explicit branch prediction so that
+// the CPU back-end can hint the processor and also so that
+// code blocks can be reordered such that the predicted path
+// sees a more linear flow, thus improving cache behavior, etc.
+//
+// The following two macros provide us with a way to utilize this
+// compiler feature.  Use __predict_true() if you expect the expression
+// to evaluate to true, and __predict_false() if you expect the
+// expression to evaluate to false.
+//
+// A few notes about usage:
+//
+//	* Generally, __predict_false() error condition checks (unless
+//	  you have some _strong_ reason to do otherwise, in which case
+//	  document it), and/or __predict_true() `no-error' condition
+//	  checks, assuming you want to optimize for the no-error case.
+//
+//	* Other than that, if you don't know the likelihood of a test
+//	  succeeding from empirical or other `hard' evidence, don't
+//	  make predictions.
+//
+//	* These are meant to be used in places that are run `a lot'.
+//	  It is wasteful to make predictions in code that is run
+//	  seldomly (e.g. at subsystem initialization time) as the
+//	  basic block reordering that this affects can often generate
+//	  larger code.
+
+// We define this here since <stddef.h>, <sys/queue.h>, and <sys/types.h>
+// require it.
+
+// Given the pointer x to the member m of the struct s, return
+// a pointer to the containing structure.  When using GCC, we first
+// assign pointer x to a local variable, to check that its type is
+// compatible with member m.
+
+// Compiler-dependent macros to declare that functions take printf-like
+// or scanf-like arguments.  They are null except for versions of gcc
+// that are known to support the features properly (old versions of gcc-2
+// didn't permit keeping the keywords out of the application namespace).
+
+// Compiler-dependent macros that rely on FreeBSD-specific extensions.
+
+// Embed the rcs id of a source file in the resulting library.  Note that in
+// more recent ELF binutils, we use .ident allowing the ID to be stripped.
+// Usage:
+//	__FBSDID("$FreeBSD$");
+
+// -
+// The following definitions are an extension of the behavior originally
+// implemented in <sys/_posix.h>, but with a different level of granularity.
+// POSIX.1 requires that the macros we test be defined before any standard
+// header file is included.
+//
+// Here's a quick run-down of the versions:
+//  defined(_POSIX_SOURCE)		1003.1-1988
+//  _POSIX_C_SOURCE == 1		1003.1-1990
+//  _POSIX_C_SOURCE == 2		1003.2-1992 C Language Binding Option
+//  _POSIX_C_SOURCE == 199309		1003.1b-1993
+//  _POSIX_C_SOURCE == 199506		1003.1c-1995, 1003.1i-1995,
+//					and the omnibus ISO/IEC 9945-1: 1996
+//  _POSIX_C_SOURCE == 200112		1003.1-2001
+//  _POSIX_C_SOURCE == 200809		1003.1-2008
+//
+// In addition, the X/Open Portability Guide, which is now the Single UNIX
+// Specification, defines a feature-test macro which indicates the version of
+// that specification, and which subsumes _POSIX_C_SOURCE.
+//
+// Our macros begin with two underscores to avoid namespace screwage.
+
+// Deal with IEEE Std. 1003.1-1990, in which _POSIX_C_SOURCE == 1.
+
+// Deal with IEEE Std. 1003.2-1992, in which _POSIX_C_SOURCE == 2.
+
+// Deal with various X/Open Portability Guides and Single UNIX Spec.
+
+// Deal with all versions of POSIX.  The ordering relative to the tests above is
+// important.
+// -
+// Deal with _ANSI_SOURCE:
+// If it is defined, and no other compilation environment is explicitly
+// requested, then define our internal feature-test macros to zero.  This
+// makes no difference to the preprocessor (undefined symbols in preprocessing
+// expressions are defined to have value zero), but makes it more convenient for
+// a test program to print out the values.
+//
+// If a program mistakenly defines _ANSI_SOURCE and some other macro such as
+// _POSIX_C_SOURCE, we will assume that it wants the broader compilation
+// environment (and in fact we will never get here).
+
+// User override __EXT1_VISIBLE
+
+// Old versions of GCC use non-standard ARM arch symbols; acle-compat.h
+// translates them to __ARM_ARCH and the modern feature symbols defined by ARM.
+
+// Nullability qualifiers: currently only supported by Clang.
+
+// Type Safety Checking
+//
+// Clang provides additional attributes to enable checking type safety
+// properties that cannot be enforced by the C type system.
+
+// Lock annotations.
+//
+// Clang provides support for doing basic thread-safety tests at
+// compile-time, by marking which locks will/should be held when
+// entering/leaving a functions.
+//
+// Furthermore, it is also possible to annotate variables and structure
+// members to enforce that they are only accessed when certain locks are
+// held.
+
+// Structure implements a lock.
+
+// Function acquires an exclusive or shared lock.
+
+// Function attempts to acquire an exclusive or shared lock.
+
+// Function releases a lock.
+
+// Function asserts that an exclusive or shared lock is held.
+
+// Function requires that an exclusive or shared lock is or is not held.
+
+// Function should not be analyzed.
+
+// Function or variable should not be sanitized, e.g., by AddressSanitizer.
+// GCC has the nosanitize attribute, but as a function attribute only, and
+// warns on use as a variable attribute.
+
+// Guard variables and structure members by lock.
+
+// Alignment builtins for better type checking and improved code generation.
+// Provide fallback versions for other compilers (GCC/Clang < 10):

+
+// Testing against Clang-specific extensions.
+
+// This code has been put in place to help reduce the addition of
+// compiler specific defines in FreeBSD code.  It helps to aid in
+// having a compiler-agnostic source tree.
+
+// Compiler memory barriers, specific to gcc and clang.
+
+// XXX: if __GNUC__ >= 2: not tested everywhere originally, where replaced
+
+// Macro to test if we're using a specific version of gcc or later.
+
+// The __CONCAT macro is used to concatenate parts of symbol names, e.g.
+// with "#define OLD(foo) __CONCAT(old,foo)", OLD(foo) produces oldfoo.
+// The __CONCAT macro is a bit tricky to use if it must work in non-ANSI
+// mode -- there must be no spaces between its arguments, and for nested
+// __CONCAT's, all the __CONCAT's must be at the left.  __CONCAT can also
+// concatenate double-quoted strings produced by the __STRING macro, but
+// this only works with ANSI C.
+//
+// __XSTRING is like __STRING, but it expands any macros in its argument
+// first.  It is only available with ANSI C.
+
+// Compiler-dependent macros to help declare dead (non-returning) and
+// pure (no side effects) functions, and unused variables.  They are
+// null except for versions of gcc that are known to support the features
+// properly (old versions of gcc-2 supported the dead and pure features
+// in a different (wrong) way).  If we do not provide an implementation
+// for a given compiler, let the compile fail if it is told to use
+// a feature that we cannot live without.
+
+// Keywords added in C11.
+
+// Emulation of C11 _Generic().  Unlike the previously defined C11
+// keywords, it is not possible to implement this using exactly the same
+// syntax.  Therefore implement something similar under the name
+// __generic().  Unlike _Generic(), this macro can only distinguish
+// between a single type, so it requires nested invocations to
+// distinguish multiple cases.
+
+// C99 Static array indices in function parameter declarations.  Syntax such as:
+// void bar(int myArray[static 10]);
+// is allowed in C99 but not in C++.  Define __min_size appropriately so
+// headers using it can be compiled in either language.  Use like this:
+// void bar(int myArray[__min_size(10)]);
+
+// XXX: should use `#if __STDC_VERSION__ < 199901'.
+
+// C++11 exposes a load of C99 stuff
+
+// GCC 2.95 provides `__restrict' as an extension to C90 to support the
+// C99-specific `restrict' type qualifier.  We happen to use `__restrict' as
+// a way to define the `restrict' type qualifier without disturbing older
+// software that is unaware of C99 keywords.
+
+// GNU C version 2.96 adds explicit branch prediction so that
+// the CPU back-end can hint the processor and also so that
+// code blocks can be reordered such that the predicted path
+// sees a more linear flow, thus improving cache behavior, etc.
+//
+// The following two macros provide us with a way to utilize this
+// compiler feature.  Use __predict_true() if you expect the expression
+// to evaluate to true, and __predict_false() if you expect the
+// expression to evaluate to false.
+//
+// A few notes about usage:
+//
+//	* Generally, __predict_false() error condition checks (unless
+//	  you have some _strong_ reason to do otherwise, in which case
+//	  document it), and/or __predict_true() `no-error' condition
+//	  checks, assuming you want to optimize for the no-error case.
+//
+//	* Other than that, if you don't know the likelihood of a test
+//	  succeeding from empirical or other `hard' evidence, don't
+//	  make predictions.
+//
+//	* These are meant to be used in places that are run `a lot'.
+//	  It is wasteful to make predictions in code that is run
+//	  seldomly (e.g. at subsystem initialization time) as the
+//	  basic block reordering that this affects can often generate
+//	  larger code.
+
+// We define this here since <stddef.h>, <sys/queue.h>, and <sys/types.h>
+// require it.
+
+// Given the pointer x to the member m of the struct s, return
+// a pointer to the containing structure.  When using GCC, we first
+// assign pointer x to a local variable, to check that its type is
+// compatible with member m.
+
+// Compiler-dependent macros to declare that functions take printf-like
+// or scanf-like arguments.  They are null except for versions of gcc
+// that are known to support the features properly (old versions of gcc-2
+// didn't permit keeping the keywords out of the application namespace).
+
+// Compiler-dependent macros that rely on FreeBSD-specific extensions.
+
+// Embed the rcs id of a source file in the resulting library.  Note that in
+// more recent ELF binutils, we use .ident allowing the ID to be stripped.
+// Usage:
+//	__FBSDID("$FreeBSD$");
+
+// -
+// The following definitions are an extension of the behavior originally
+// implemented in <sys/_posix.h>, but with a different level of granularity.
+// POSIX.1 requires that the macros we test be defined before any standard
+// header file is included.
+//
+// Here's a quick run-down of the versions:
+//  defined(_POSIX_SOURCE)		1003.1-1988
+//  _POSIX_C_SOURCE == 1		1003.1-1990
+//  _POSIX_C_SOURCE == 2		1003.2-1992 C Language Binding Option
+//  _POSIX_C_SOURCE == 199309		1003.1b-1993
+//  _POSIX_C_SOURCE == 199506		1003.1c-1995, 1003.1i-1995,
+//					and the omnibus ISO/IEC 9945-1: 1996
+//  _POSIX_C_SOURCE == 200112		1003.1-2001
+//  _POSIX_C_SOURCE == 200809		1003.1-2008
+//
+// In addition, the X/Open Portability Guide, which is now the Single UNIX
+// Specification, defines a feature-test macro which indicates the version of
+// that specification, and which subsumes _POSIX_C_SOURCE.
+//
+// Our macros begin with two underscores to avoid namespace screwage.
+
+// Deal with IEEE Std. 1003.1-1990, in which _POSIX_C_SOURCE == 1.
+
+// Deal with IEEE Std. 1003.2-1992, in which _POSIX_C_SOURCE == 2.
+
+// Deal with various X/Open Portability Guides and Single UNIX Spec.
+
+// Deal with all versions of POSIX.  The ordering relative to the tests above is
+// important.
+// -
+// Deal with _ANSI_SOURCE:
+// If it is defined, and no other compilation environment is explicitly
+// requested, then define our internal feature-test macros to zero.  This
+// makes no difference to the preprocessor (undefined symbols in preprocessing
+// expressions are defined to have value zero), but makes it more convenient for
+// a test program to print out the values.
+//
+// If a program mistakenly defines _ANSI_SOURCE and some other macro such as
+// _POSIX_C_SOURCE, we will assume that it wants the broader compilation
+// environment (and in fact we will never get here).
+
+// User override __EXT1_VISIBLE
+
+// Old versions of GCC use non-standard ARM arch symbols; acle-compat.h
+// translates them to __ARM_ARCH and the modern feature symbols defined by ARM.
+
+// Nullability qualifiers: currently only supported by Clang.
+
+// Type Safety Checking
+//
+// Clang provides additional attributes to enable checking type safety
+// properties that cannot be enforced by the C type system.
+
+// Lock annotations.
+//
+// Clang provides support for doing basic thread-safety tests at
+// compile-time, by marking which locks will/should be held when
+// entering/leaving a functions.
+//
+// Furthermore, it is also possible to annotate variables and structure
+// members to enforce that they are only accessed when certain locks are
+// held.
+
+// Structure implements a lock.
+
+// Function acquires an exclusive or shared lock.
+
+// Function attempts to acquire an exclusive or shared lock.
+
+// Function releases a lock.
+
+// Function asserts that an exclusive or shared lock is held.
+
+// Function requires that an exclusive or shared lock is or is not held.
+
+// Function should not be analyzed.
+
+// Function or variable should not be sanitized, e.g., by AddressSanitizer.
+// GCC has the nosanitize attribute, but as a function attribute only, and
+// warns on use as a variable attribute.
+
+// Guard variables and structure members by lock.
+
+// Alignment builtins for better type checking and improved code generation.
+// Provide fallback versions for other compilers (GCC/Clang < 10):

+//
+// NOTE: rune_t is not covered by ANSI nor other standards, and should not
+// be instantiated outside of lib/libc/locale.  Use wchar_t.  wint_t and

+
+// Testing against Clang-specific extensions.
+
+// This code has been put in place to help reduce the addition of
+// compiler specific defines in FreeBSD code.  It helps to aid in
+// having a compiler-agnostic source tree.
+
+// Compiler memory barriers, specific to gcc and clang.
+
+// XXX: if __GNUC__ >= 2: not tested everywhere originally, where replaced
+
+// Macro to test if we're using a specific version of gcc or later.
+
+// The __CONCAT macro is used to concatenate parts of symbol names, e.g.
+// with "#define OLD(foo) __CONCAT(old,foo)", OLD(foo) produces oldfoo.
+// The __CONCAT macro is a bit tricky to use if it must work in non-ANSI
+// mode -- there must be no spaces between its arguments, and for nested
+// __CONCAT's, all the __CONCAT's must be at the left.  __CONCAT can also
+// concatenate double-quoted strings produced by the __STRING macro, but
+// this only works with ANSI C.
+//
+// __XSTRING is like __STRING, but it expands any macros in its argument
+// first.  It is only available with ANSI C.
+
+// Compiler-dependent macros to help declare dead (non-returning) and
+// pure (no side effects) functions, and unused variables.  They are
+// null except for versions of gcc that are known to support the features
+// properly (old versions of gcc-2 supported the dead and pure features
+// in a different (wrong) way).  If we do not provide an implementation
+// for a given compiler, let the compile fail if it is told to use
+// a feature that we cannot live without.
+
+// Keywords added in C11.
+
+// Emulation of C11 _Generic().  Unlike the previously defined C11
+// keywords, it is not possible to implement this using exactly the same
+// syntax.  Therefore implement something similar under the name
+// __generic().  Unlike _Generic(), this macro can only distinguish
+// between a single type, so it requires nested invocations to
+// distinguish multiple cases.
+
+// C99 Static array indices in function parameter declarations.  Syntax such as:
+// void bar(int myArray[static 10]);
+// is allowed in C99 but not in C++.  Define __min_size appropriately so
+// headers using it can be compiled in either language.  Use like this:
+// void bar(int myArray[__min_size(10)]);
+
+// XXX: should use `#if __STDC_VERSION__ < 199901'.
+
+// C++11 exposes a load of C99 stuff
+
+// GCC 2.95 provides `__restrict' as an extension to C90 to support the
+// C99-specific `restrict' type qualifier.  We happen to use `__restrict' as
+// a way to define the `restrict' type qualifier without disturbing older
+// software that is unaware of C99 keywords.
+
+// GNU C version 2.96 adds explicit branch prediction so that
+// the CPU back-end can hint the processor and also so that
+// code blocks can be reordered such that the predicted path
+// sees a more linear flow, thus improving cache behavior, etc.
+//
+// The following two macros provide us with a way to utilize this
+// compiler feature.  Use __predict_true() if you expect the expression
+// to evaluate to true, and __predict_false() if you expect the
+// expression to evaluate to false.
+//
+// A few notes about usage:
+//
+//	* Generally, __predict_false() error condition checks (unless
+//	  you have some _strong_ reason to do otherwise, in which case
+//	  document it), and/or __predict_true() `no-error' condition
+//	  checks, assuming you want to optimize for the no-error case.
+//
+//	* Other than that, if you don't know the likelihood of a test
+//	  succeeding from empirical or other `hard' evidence, don't
+//	  make predictions.
+//
+//	* These are meant to be used in places that are run `a lot'.
+//	  It is wasteful to make predictions in code that is run
+//	  seldomly (e.g. at subsystem initialization time) as the
+//	  basic block reordering that this affects can often generate
+//	  larger code.
+
+// We define this here since <stddef.h>, <sys/queue.h>, and <sys/types.h>
+// require it.
+
+// Given the pointer x to the member m of the struct s, return
+// a pointer to the containing structure.  When using GCC, we first
+// assign pointer x to a local variable, to check that its type is
+// compatible with member m.
+
+// Compiler-dependent macros to declare that functions take printf-like
+// or scanf-like arguments.  They are null except for versions of gcc
+// that are known to support the features properly (old versions of gcc-2
+// didn't permit keeping the keywords out of the application namespace).
+
+// Compiler-dependent macros that rely on FreeBSD-specific extensions.
+
+// Embed the rcs id of a source file in the resulting library.  Note that in
+// more recent ELF binutils, we use .ident allowing the ID to be stripped.
+// Usage:
+//	__FBSDID("$FreeBSD$");
+
+// -
+// The following definitions are an extension of the behavior originally
+// implemented in <sys/_posix.h>, but with a different level of granularity.
+// POSIX.1 requires that the macros we test be defined before any standard
+// header file is included.
+//
+// Here's a quick run-down of the versions:
+//  defined(_POSIX_SOURCE)		1003.1-1988
+//  _POSIX_C_SOURCE == 1		1003.1-1990
+//  _POSIX_C_SOURCE == 2		1003.2-1992 C Language Binding Option
+//  _POSIX_C_SOURCE == 199309		1003.1b-1993
+//  _POSIX_C_SOURCE == 199506		1003.1c-1995, 1003.1i-1995,
+//					and the omnibus ISO/IEC 9945-1: 1996
+//  _POSIX_C_SOURCE == 200112		1003.1-2001
+//  _POSIX_C_SOURCE == 200809		1003.1-2008
+//
+// In addition, the X/Open Portability Guide, which is now the Single UNIX
+// Specification, defines a feature-test macro which indicates the version of
+// that specification, and which subsumes _POSIX_C_SOURCE.
+//
+// Our macros begin with two underscores to avoid namespace screwage.
+
+// Deal with IEEE Std. 1003.1-1990, in which _POSIX_C_SOURCE == 1.
+
+// Deal with IEEE Std. 1003.2-1992, in which _POSIX_C_SOURCE == 2.
+
+// Deal with various X/Open Portability Guides and Single UNIX Spec.
+
+// Deal with all versions of POSIX.  The ordering relative to the tests above is
+// important.
+// -
+// Deal with _ANSI_SOURCE:
+// If it is defined, and no other compilation environment is explicitly
+// requested, then define our internal feature-test macros to zero.  This
+// makes no difference to the preprocessor (undefined symbols in preprocessing
+// expressions are defined to have value zero), but makes it more convenient for
+// a test program to print out the values.
+//
+// If a program mistakenly defines _ANSI_SOURCE and some other macro such as
+// _POSIX_C_SOURCE, we will assume that it wants the broader compilation
+// environment (and in fact we will never get here).
+
+// User override __EXT1_VISIBLE
+
+// Old versions of GCC use non-standard ARM arch symbols; acle-compat.h
+// translates them to __ARM_ARCH and the modern feature symbols defined by ARM.
+
+// Nullability qualifiers: currently only supported by Clang.
+
+// Type Safety Checking
+//
+// Clang provides additional attributes to enable checking type safety
+// properties that cannot be enforced by the C type system.
+
+// Lock annotations.
+//
+// Clang provides support for doing basic thread-safety tests at
+// compile-time, by marking which locks will/should be held when
+// entering/leaving a functions.
+//
+// Furthermore, it is also possible to annotate variables and structure
+// members to enforce that they are only accessed when certain locks are
+// held.
+
+// Structure implements a lock.
+
+// Function acquires an exclusive or shared lock.
+
+// Function attempts to acquire an exclusive or shared lock.
+
+// Function releases a lock.
+
+// Function asserts that an exclusive or shared lock is held.
+
+// Function requires that an exclusive or shared lock is or is not held.
+
+// Function should not be analyzed.
+
+// Function or variable should not be sanitized, e.g., by AddressSanitizer.
+// GCC has the nosanitize attribute, but as a function attribute only, and
+// warns on use as a variable attribute.
+
+// Guard variables and structure members by lock.
+
+// Alignment builtins for better type checking and improved code generation.
+// Provide fallback versions for other compilers (GCC/Clang < 10):

+
+// This header file serves to group a set of well known defines and to
+// set these for each instruction set architecture.  These defines may
+// be divided into two groups;  characteristics of the processor and
+// implementation choices for Solaris on a processor.
+//
+// Processor Characteristics:
+//
+// _LITTLE_ENDIAN / _BIG_ENDIAN:
+//	The natural byte order of the processor.  A pointer to an int points
+//	to the least/most significant byte of that int.
+//
+// _STACK_GROWS_UPWARD / _STACK_GROWS_DOWNWARD:
+//	The processor specific direction of stack growth.  A push onto the
+//	stack increases/decreases the stack pointer, so it stores data at
+//	successively higher/lower addresses.  (Stackless machines ignored
+//	without regrets).
+//
+// _LONG_LONG_HTOL / _LONG_LONG_LTOH:
+//	A pointer to a long long points to the most/least significant long
+//	within that long long.
+//
+// _BIT_FIELDS_HTOL / _BIT_FIELDS_LTOH:
+//	The C compiler assigns bit fields from the high/low to the low/high end
+//	of an int (most to least significant vs. least to most significant).
+//
+// _IEEE_754:
+//	The processor (or supported implementations of the processor)
+//	supports the ieee-754 floating point standard.  No other floating
+//	point standards are supported (or significant).  Any other supported
+//	floating point formats are expected to be cased on the ISA processor
+//	symbol.
+//
+// _CHAR_IS_UNSIGNED / _CHAR_IS_SIGNED:
+//	The C Compiler implements objects of type `char' as `unsigned' or
+//	`signed' respectively.  This is really an implementation choice of
+//	the compiler writer, but it is specified in the ABI and tends to
+//	be uniform across compilers for an instruction set architecture.
+//	Hence, it has the properties of a processor characteristic.
+//
+// _CHAR_ALIGNMENT / _SHORT_ALIGNMENT / _INT_ALIGNMENT / _LONG_ALIGNMENT /
+// _LONG_LONG_ALIGNMENT / _DOUBLE_ALIGNMENT / _LONG_DOUBLE_ALIGNMENT /
+// _POINTER_ALIGNMENT / _FLOAT_ALIGNMENT:
+//	The ABI defines alignment requirements of each of the primitive
+//	object types.  Some, if not all, may be hardware requirements as
+// 	well.  The values are expressed in "byte-alignment" units.
+//
+// _MAX_ALIGNMENT:
+//	The most stringent alignment requirement as specified by the ABI.
+//	Equal to the maximum of all the above _XXX_ALIGNMENT values.
+//
+// _MAX_ALIGNMENT_TYPE:
+// 	The name of the C type that has the value descried in _MAX_ALIGNMENT.
+//
+// _ALIGNMENT_REQUIRED:
+//	True or false (1 or 0) whether or not the hardware requires the ABI
+//	alignment.
+//
+// _LONG_LONG_ALIGNMENT_32
+//	The 32-bit ABI supported by a 64-bit kernel may have different
+//	alignment requirements for primitive object types.  The value of this
+//	identifier is expressed in "byte-alignment" units.
+//
+// _HAVE_CPUID_INSN
+//	This indicates that the architecture supports the 'cpuid'
+//	instruction as defined by Intel.  (Intel allows other vendors
+//	to extend the instruction for their own purposes.)
+//
+//
+// Implementation Choices:
+//
+// _ILP32 / _LP64:
+//	This specifies the compiler data type implementation as specified in
+//	the relevant ABI.  The choice between these is strongly influenced
+//	by the underlying hardware, but is not absolutely tied to it.
+//	Currently only two data type models are supported:
+//
+//	_ILP32:
+//		Int/Long/Pointer are 32 bits.  This is the historical UNIX
+//		and Solaris implementation.  Due to its historical standing,
+//		this is the default case.
+//
+//	_LP64:
+//		Long/Pointer are 64 bits, Int is 32 bits.  This is the chosen
+//		implementation for 64-bit ABIs such as SPARC V9.
+//
+//	_I32LPx:
+//		A compilation environment where 'int' is 32-bit, and
+//		longs and pointers are simply the same size.
+//
+//	In all cases, Char is 8 bits and Short is 16 bits.
+//
+// _SUNOS_VTOC_8 / _SUNOS_VTOC_16 / _SVR4_VTOC_16:
+//	This specifies the form of the disk VTOC (or label):
+//
+//	_SUNOS_VTOC_8:
+//		This is a VTOC form which is upwardly compatible with the
+//		SunOS 4.x disk label and allows 8 partitions per disk.
+//
+//	_SUNOS_VTOC_16:
+//		In this format the incore vtoc image matches the ondisk
+//		version.  It allows 16 slices per disk, and is not
+//		compatible with the SunOS 4.x disk label.
+//
+//	Note that these are not the only two VTOC forms possible and
+//	additional forms may be added.  One possible form would be the
+//	SVr4 VTOC form.  The symbol for that is reserved now, although
+//	it is not implemented.
+//
+//	_SVR4_VTOC_16:
+//		This VTOC form is compatible with the System V Release 4
+//		VTOC (as implemented on the SVr4 Intel and 3b ports) with
+//		16 partitions per disk.
+//
+//
+// _DMA_USES_PHYSADDR / _DMA_USES_VIRTADDR
+//	This describes the type of addresses used by system DMA:
+//
+//	_DMA_USES_PHYSADDR:
+//		This type of DMA, used in the x86 implementation,
+//		requires physical addresses for DMA buffers.  The 24-bit
+//		addresses used by some legacy boards is the source of the
+//		"low-memory" (<16MB) requirement for some devices using DMA.
+//
+//	_DMA_USES_VIRTADDR:
+//		This method of DMA allows the use of virtual addresses for
+//		DMA transfers.
+//
+// _FIRMWARE_NEEDS_FDISK / _NO_FDISK_PRESENT
+//      This indicates the presence/absence of an fdisk table.
+//
+//      _FIRMWARE_NEEDS_FDISK
+//              The fdisk table is required by system firmware.  If present,
+//              it allows a disk to be subdivided into multiple fdisk
+//              partitions, each of which is equivalent to a separate,
+//              virtual disk.  This enables the co-existence of multiple
+//              operating systems on a shared hard disk.
+//
+//      _NO_FDISK_PRESENT
+//              If the fdisk table is absent, it is assumed that the entire
+//              media is allocated for a single operating system.
+//
+// _HAVE_TEM_FIRMWARE
+//	Defined if this architecture has the (fallback) option of
+//	using prom_* calls for doing I/O if a suitable kernel driver
+//	is not available to do it.
+//
+// _DONT_USE_1275_GENERIC_NAMES
+//		Controls whether or not device tree node names should
+//		comply with the IEEE 1275 "Generic Names" Recommended
+//		Practice. With _DONT_USE_GENERIC_NAMES, device-specific
+//		names identifying the particular device will be used.
+//
+// __i386_COMPAT
+//	This indicates whether the i386 ABI is supported as a *non-native*
+//	mode for the platform.  When this symbol is defined:
+//	-	32-bit xstat-style system calls are enabled
+//	-	32-bit xmknod-style system calls are enabled
+//	-	32-bit system calls use i386 sizes -and- alignments
+//
+//	Note that this is NOT defined for the i386 native environment!
+//
+// __x86
+//	This is ONLY a synonym for defined(__i386) || defined(__amd64)
+//	which is useful only insofar as these two architectures share
+//	common attributes.  Analogous to __sparc.
+//
+// _PSM_MODULES
+//	This indicates whether or not the implementation uses PSM
+//	modules for processor support, reading /etc/mach from inside
+//	the kernel to extract a list.
+//
+// _RTC_CONFIG
+//	This indicates whether or not the implementation uses /etc/rtc_config
+//	to configure the real-time clock in the kernel.
+//
+// _UNIX_KRTLD
+//	This indicates that the implementation uses a dynamically
+//	linked unix + krtld to form the core kernel image at boot
+//	time, or (in the absence of this symbol) a prelinked kernel image.
+//
+// _OBP
+//	This indicates the firmware interface is OBP.
+//
+// _SOFT_HOSTID
+//	This indicates that the implementation obtains the hostid
+//	from the file /etc/hostid, rather than from hardware.
+
+// The following set of definitions characterize Solaris on AMD's
+// 64-bit systems.
+
+// Define the appropriate "processor characteristics"
+
+// Different alignment constraints for the i386 ABI in compatibility mode
+
+// Define the appropriate "implementation choices".
+
+// The feature test macro __i386 is generic for all processors implementing
+// the Intel 386 instruction set or a superset of it.  Specifically, this
+// includes all members of the 386, 486, and Pentium family of processors.
+
+// Values of _POSIX_C_SOURCE
+//
+//		undefined   not a POSIX compilation
+//		1	    POSIX.1-1990 compilation
+//		2	    POSIX.2-1992 compilation
+//		199309L	    POSIX.1b-1993 compilation (Real Time)
+//		199506L	    POSIX.1c-1995 compilation (POSIX Threads)
+//		200112L	    POSIX.1-2001 compilation (Austin Group Revision)
+//		200809L     POSIX.1-2008 compilation
+
+// The feature test macros __XOPEN_OR_POSIX, _STRICT_STDC, _STRICT_SYMBOLS,
+// and _STDC_C99 are Sun implementation specific macros created in order to
+// compress common standards specified feature test macros for easier reading.
+// These macros should not be used by the application developer as
+// unexpected results may occur. Instead, the user should reference
+// standards(7) for correct usage of the standards feature test macros.
+//
+// __XOPEN_OR_POSIX     Used in cases where a symbol is defined by both
+//                      X/Open or POSIX or in the negative, when neither
+//                      X/Open or POSIX defines a symbol.
+//
+// _STRICT_STDC         __STDC__ is specified by the C Standards and defined
+//                      by the compiler. For Sun compilers the value of
+//                      __STDC__ is either 1, 0, or not defined based on the
+//                      compilation mode (see cc(1)). When the value of
+//                      __STDC__ is 1 and in the absence of any other feature
+//                      test macros, the namespace available to the application
+//                      is limited to only those symbols defined by the C
+//                      Standard. _STRICT_STDC provides a more readable means
+//                      of identifying symbols defined by the standard, or in
+//                      the negative, symbols that are extensions to the C
+//                      Standard. See additional comments for GNU C differences.
+//
+// _STDC_C99            __STDC_VERSION__ is specified by the C standards and
+//                      defined by the compiler and indicates the version of
+//                      the C standard. A value of 199901L indicates a
+//                      compiler that complies with ISO/IEC 9899:1999, other-
+//                      wise known as the C99 standard.
+//
+// _STDC_C11		Like _STDC_C99 except that the value of __STDC_VERSION__
+//                      is 201112L indicating a compiler that compiles with
+//                      ISO/IEC 9899:2011, otherwise known as the C11 standard.
+//
+// _STRICT_SYMBOLS	Used in cases where symbol visibility is restricted
+//                      by the standards, and the user has not explicitly
+//                      relaxed the strictness via __EXTENSIONS__.
+
+// ISO/IEC 9899:1990 and it's revisions, ISO/IEC 9899:1999 and ISO/IEC
+// 99899:2011 specify the following predefined macro name:
+//
+// __STDC__	The integer constant 1, intended to indicate a conforming
+//		implementation.
+//
+// Furthermore, a strictly conforming program shall use only those features
+// of the language and library specified in these standards. A conforming
+// implementation shall accept any strictly conforming program.
+//
+// Based on these requirements, Sun's C compiler defines __STDC__ to 1 for
+// strictly conforming environments and __STDC__ to 0 for environments that
+// use ANSI C semantics but allow extensions to the C standard. For non-ANSI
+// C semantics, Sun's C compiler does not define __STDC__.
+//
+// The GNU C project interpretation is that __STDC__ should always be defined
+// to 1 for compilation modes that accept ANSI C syntax regardless of whether
+// or not extensions to the C standard are used. Violations of conforming
+// behavior are conditionally flagged as warnings via the use of the
+// -pedantic option. In addition to defining __STDC__ to 1, the GNU C
+// compiler also defines __STRICT_ANSI__ as a means of specifying strictly
+// conforming environments using the -ansi or -std=<standard> options.
+//
+// In the absence of any other compiler options, Sun and GNU set the value
+// of __STDC__ as follows when using the following options:
+//
+//				Value of __STDC__  __STRICT_ANSI__
+//
+// cc -Xa (default)			0	      undefined
+// cc -Xt (transitional)		0             undefined
+// cc -Xc (strictly conforming)		1	      undefined
+// cc -Xs (K&R C)		    undefined	      undefined
+//
+// gcc (default)			1	      undefined
+// gcc -ansi, -std={c89, c99,...)	1               defined
+// gcc -traditional (K&R)	    undefined	      undefined
+//
+// The default compilation modes for Sun C compilers versus GNU C compilers
+// results in a differing value for __STDC__ which results in a more
+// restricted namespace when using Sun compilers. To allow both GNU and Sun
+// interpretations to peacefully co-exist, we use the following Sun
+// implementation _STRICT_STDC_ macro:
+
+// Compiler complies with ISO/IEC 9899:1999 or ISO/IEC 9989:2011
+
+// Use strict symbol visibility.
+
+// This is a variant of _STRICT_SYMBOLS that is meant to cover headers that are
+// governed by POSIX, but have not been governed by ISO C. One can go two ways
+// on what should happen if an application actively includes (not transitively)
+// a header that isn't part of the ISO C spec, we opt to say that if someone has
+// gone out of there way then they're doing it for a reason and that is an act
+// of non-compliance and therefore it's not up to us to hide away every symbol.
+//
+// In general, prefer using _STRICT_SYMBOLS, but this is here in particular for
+// cases where in the past we have only used a POSIX related check and we don't
+// wish to make something stricter. Often applications are relying on the
+// ability to, or more realistically unwittingly, have _STRICT_STDC declared and
+// still use these interfaces.
+
+// Large file interfaces:
+//
+//	_LARGEFILE_SOURCE
+//		1		large file-related additions to POSIX
+//				interfaces requested (fseeko, etc.)
+//	_LARGEFILE64_SOURCE
+//		1		transitional large-file-related interfaces
+//				requested (seek64, stat64, etc.)
+//
+// The corresponding announcement macros are respectively:
+//	_LFS_LARGEFILE
+//	_LFS64_LARGEFILE
+// (These are set in <unistd.h>.)
+//
+// Requesting _LARGEFILE64_SOURCE implies requesting _LARGEFILE_SOURCE as
+// well.
+//
+// The large file interfaces are made visible regardless of the initial values
+// of the feature test macros under certain circumstances:
+//    -	If no explicit standards-conforming environment is requested (neither
+//	of _POSIX_SOURCE nor _XOPEN_SOURCE is defined and the value of
+//	__STDC__ does not imply standards conformance).
+//    -	Extended system interfaces are explicitly requested (__EXTENSIONS__
+//	is defined).
+//    -	Access to in-kernel interfaces is requested (_KERNEL or _KMEMUSER is
+//	defined).  (Note that this dependency is an artifact of the current
+//	kernel implementation and may change in future releases.)
+
+// Large file compilation environment control:
+//
+// The setting of _FILE_OFFSET_BITS controls the size of various file-related
+// types and governs the mapping between file-related source function symbol
+// names and the corresponding binary entry points.
+//
+// In the 32-bit environment, the default value is 32; if not set, set it to
+// the default here, to simplify tests in other headers.
+//
+// In the 64-bit compilation environment, the only value allowed is 64.
+
+// Use of _XOPEN_SOURCE
+//
+// The following X/Open specifications are supported:

+// Open Group Technical Standard, Issue 7 (XPG7), also referred to as
+//    IEEE Std. 1003.1-2008 and ISO/IEC 9945:2009.
+//
+// XPG4v2 is also referred to as UNIX 95 (SUS or SUSv1).
+// XPG5 is also referred to as UNIX 98 or the Single Unix Specification,
+//     Version 2 (SUSv2)
+// XPG6 is the result of a merge of the X/Open and POSIX specifications
+//     and as such is also referred to as IEEE Std. 1003.1-2001 in
+//     addition to UNIX 03 and SUSv3.
+// XPG7 is also referred to as UNIX 08 and SUSv4.
+//
+// When writing a conforming X/Open application, as per the specification
+// requirements, the appropriate feature test macros must be defined at
+// compile time. These are as follows. For more info, see standards(7).
+//
+// Feature Test Macro				     Specification
+// ------------------------------------------------  -------------
+// _XOPEN_SOURCE                                         XPG3
+// _XOPEN_SOURCE && _XOPEN_VERSION = 4                   XPG4
+// _XOPEN_SOURCE && _XOPEN_SOURCE_EXTENDED = 1           XPG4v2
+// _XOPEN_SOURCE = 500                                   XPG5
+// _XOPEN_SOURCE = 600  (or POSIX_C_SOURCE=200112L)      XPG6
+// _XOPEN_SOURCE = 700  (or POSIX_C_SOURCE=200809L)      XPG7
+//
+// In order to simplify the guards within the headers, the following
+// implementation private test macros have been created. Applications
+// must NOT use these private test macros as unexpected results will
+// occur.
+//
+// Note that in general, the use of these private macros is cumulative.
+// For example, the use of _XPG3 with no other restrictions on the X/Open
+// namespace will make the symbols visible for XPG3 through XPG6
+// compilation environments. The use of _XPG4_2 with no other X/Open
+// namespace restrictions indicates that the symbols were introduced in
+// XPG4v2 and are therefore visible for XPG4v2 through XPG6 compilation
+// environments, but not for XPG3 or XPG4 compilation environments.
+//
+// _XPG3    X/Open Portability Guide, Issue 3 (XPG3)
+// _XPG4    X/Open CAE Specification, Issue 4 (XPG4)
+// _XPG4_2  X/Open CAE Specification, Issue 4, Version 2 (XPG4v2/UNIX 95/SUS)
+// _XPG5    X/Open CAE Specification, Issue 5 (XPG5/UNIX 98/SUSv2)
+// _XPG6    Open Group Technical Standard, Issue 6 (XPG6/UNIX 03/SUSv3)
+// _XPG7    Open Group Technical Standard, Issue 7 (XPG7/UNIX 08/SUSv4)
+
+// X/Open Portability Guide, Issue 3
+
+// _XOPEN_VERSION is defined by the X/Open specifications and is not
+// normally defined by the application, except in the case of an XPG4
+// application.  On the implementation side, _XOPEN_VERSION defined with
+// the value of 3 indicates an XPG3 application. _XOPEN_VERSION defined
+// with the value of 4 indicates an XPG4 or XPG4v2 (UNIX 95) application.
+// _XOPEN_VERSION  defined with a value of 500 indicates an XPG5 (UNIX 98)
+// application and with a value of 600 indicates an XPG6 (UNIX 03)
+// application and with a value of 700 indicates an XPG7 (UNIX 08).
+// The appropriate version is determined by the use of the
+// feature test macros described earlier.  The value of _XOPEN_VERSION
+// defaults to 3 otherwise indicating support for XPG3 applications.
+
+// ANSI C and ISO 9899:1990 say the type long long doesn't exist in strictly
+// conforming environments.  ISO 9899:1999 says it does.
+//
+// The presence of _LONGLONG_TYPE says "long long exists" which is therefore
+// defined in all but strictly conforming environments that disallow it.
+
+// The following macro defines a value for the ISO C99 restrict
+// keyword so that _RESTRICT_KYWD resolves to "restrict" if
+// an ISO C99 compiler is used, "__restrict" for c++ and "" (null string)
+// if any other compiler is used. This allows for the use of single
+// prototype declarations regardless of compiler version.
+
+// The following macro defines a value for the ISO C11 _Noreturn
+// keyword so that _NORETURN_KYWD resolves to "_Noreturn" if
+// an ISO C11 compiler is used and "" (null string) if any other
+// compiler is used. This allows for the use of single prototype
+// declarations regardless of compiler version.
+
+// ISO/IEC 9899:2011 Annex K
+
+// The following macro indicates header support for the ANSI C++
+// standard.  The ISO/IEC designation for this is ISO/IEC FDIS 14882.
+
+// The following macro indicates header support for the C99 standard,
+// ISO/IEC 9899:1999, Programming Languages - C.
+
+// The following macro indicates header support for the C11 standard,
+// ISO/IEC 9899:2011, Programming Languages - C.
+
+// The following macro indicates header support for the C11 standard,
+// ISO/IEC 9899:2011 Annex K, Programming Languages - C.
+
+// The following macro indicates header support for DTrace. The value is an
+// integer that corresponds to the major version number for DTrace.

+
+// This header file serves to group a set of well known defines and to
+// set these for each instruction set architecture.  These defines may
+// be divided into two groups;  characteristics of the processor and
+// implementation choices for Solaris on a processor.
+//
+// Processor Characteristics:
+//
+// _LITTLE_ENDIAN / _BIG_ENDIAN:
+//	The natural byte order of the processor.  A pointer to an int points
+//	to the least/most significant byte of that int.
+//
+// _STACK_GROWS_UPWARD / _STACK_GROWS_DOWNWARD:
+//	The processor specific direction of stack growth.  A push onto the
+//	stack increases/decreases the stack pointer, so it stores data at
+//	successively higher/lower addresses.  (Stackless machines ignored
+//	without regrets).
+//
+// _LONG_LONG_HTOL / _LONG_LONG_LTOH:
+//	A pointer to a long long points to the most/least significant long
+//	within that long long.
+//
+// _BIT_FIELDS_HTOL / _BIT_FIELDS_LTOH:
+//	The C compiler assigns bit fields from the high/low to the low/high end
+//	of an int (most to least significant vs. least to most significant).
+//
+// _IEEE_754:
+//	The processor (or supported implementations of the processor)
+//	supports the ieee-754 floating point standard.  No other floating
+//	point standards are supported (or significant).  Any other supported
+//	floating point formats are expected to be cased on the ISA processor
+//	symbol.
+//
+// _CHAR_IS_UNSIGNED / _CHAR_IS_SIGNED:
+//	The C Compiler implements objects of type `char' as `unsigned' or
+//	`signed' respectively.  This is really an implementation choice of
+//	the compiler writer, but it is specified in the ABI and tends to
+//	be uniform across compilers for an instruction set architecture.
+//	Hence, it has the properties of a processor characteristic.
+//
+// _CHAR_ALIGNMENT / _SHORT_ALIGNMENT / _INT_ALIGNMENT / _LONG_ALIGNMENT /
+// _LONG_LONG_ALIGNMENT / _DOUBLE_ALIGNMENT / _LONG_DOUBLE_ALIGNMENT /
+// _POINTER_ALIGNMENT / _FLOAT_ALIGNMENT:
+//	The ABI defines alignment requirements of each of the primitive
+//	object types.  Some, if not all, may be hardware requirements as
+// 	well.  The values are expressed in "byte-alignment" units.
+//
+// _MAX_ALIGNMENT:
+//	The most stringent alignment requirement as specified by the ABI.
+//	Equal to the maximum of all the above _XXX_ALIGNMENT values.
+//
+// _MAX_ALIGNMENT_TYPE:
+// 	The name of the C type that has the value descried in _MAX_ALIGNMENT.
+//
+// _ALIGNMENT_REQUIRED:
+//	True or false (1 or 0) whether or not the hardware requires the ABI
+//	alignment.
+//
+// _LONG_LONG_ALIGNMENT_32
+//	The 32-bit ABI supported by a 64-bit kernel may have different
+//	alignment requirements for primitive object types.  The value of this
+//	identifier is expressed in "byte-alignment" units.
+//
+// _HAVE_CPUID_INSN
+//	This indicates that the architecture supports the 'cpuid'
+//	instruction as defined by Intel.  (Intel allows other vendors
+//	to extend the instruction for their own purposes.)
+//
+//
+// Implementation Choices:
+//
+// _ILP32 / _LP64:
+//	This specifies the compiler data type implementation as specified in
+//	the relevant ABI.  The choice between these is strongly influenced
+//	by the underlying hardware, but is not absolutely tied to it.
+//	Currently only two data type models are supported:
+//
+//	_ILP32:
+//		Int/Long/Pointer are 32 bits.  This is the historical UNIX
+//		and Solaris implementation.  Due to its historical standing,
+//		this is the default case.
+//
+//	_LP64:
+//		Long/Pointer are 64 bits, Int is 32 bits.  This is the chosen
+//		implementation for 64-bit ABIs such as SPARC V9.
+//
+//	_I32LPx:
+//		A compilation environment where 'int' is 32-bit, and
+//		longs and pointers are simply the same size.
+//
+//	In all cases, Char is 8 bits and Short is 16 bits.
+//
+// _SUNOS_VTOC_8 / _SUNOS_VTOC_16 / _SVR4_VTOC_16:
+//	This specifies the form of the disk VTOC (or label):
+//
+//	_SUNOS_VTOC_8:
+//		This is a VTOC form which is upwardly compatible with the
+//		SunOS 4.x disk label and allows 8 partitions per disk.
+//
+//	_SUNOS_VTOC_16:
+//		In this format the incore vtoc image matches the ondisk
+//		version.  It allows 16 slices per disk, and is not
+//		compatible with the SunOS 4.x disk label.
+//
+//	Note that these are not the only two VTOC forms possible and
+//	additional forms may be added.  One possible form would be the
+//	SVr4 VTOC form.  The symbol for that is reserved now, although
+//	it is not implemented.
+//
+//	_SVR4_VTOC_16:
+//		This VTOC form is compatible with the System V Release 4
+//		VTOC (as implemented on the SVr4 Intel and 3b ports) with
+//		16 partitions per disk.
+//
+//
+// _DMA_USES_PHYSADDR / _DMA_USES_VIRTADDR
+//	This describes the type of addresses used by system DMA:
+//
+//	_DMA_USES_PHYSADDR:
+//		This type of DMA, used in the x86 implementation,
+//		requires physical addresses for DMA buffers.  The 24-bit
+//		addresses used by some legacy boards is the source of the
+//		"low-memory" (<16MB) requirement for some devices using DMA.
+//
+//	_DMA_USES_VIRTADDR:
+//		This method of DMA allows the use of virtual addresses for
+//		DMA transfers.
+//
+// _FIRMWARE_NEEDS_FDISK / _NO_FDISK_PRESENT
+//      This indicates the presence/absence of an fdisk table.
+//
+//      _FIRMWARE_NEEDS_FDISK
+//              The fdisk table is required by system firmware.  If present,
+//              it allows a disk to be subdivided into multiple fdisk
+//              partitions, each of which is equivalent to a separate,
+//              virtual disk.  This enables the co-existence of multiple
+//              operating systems on a shared hard disk.
+//
+//      _NO_FDISK_PRESENT
+//              If the fdisk table is absent, it is assumed that the entire
+//              media is allocated for a single operating system.
+//
+// _HAVE_TEM_FIRMWARE
+//	Defined if this architecture has the (fallback) option of
+//	using prom_* calls for doing I/O if a suitable kernel driver
+//	is not available to do it.
+//
+// _DONT_USE_1275_GENERIC_NAMES
+//		Controls whether or not device tree node names should
+//		comply with the IEEE 1275 "Generic Names" Recommended
+//		Practice. With _DONT_USE_GENERIC_NAMES, device-specific
+//		names identifying the particular device will be used.
+//
+// __i386_COMPAT
+//	This indicates whether the i386 ABI is supported as a *non-native*
+//	mode for the platform.  When this symbol is defined:
+//	-	32-bit xstat-style system calls are enabled
+//	-	32-bit xmknod-style system calls are enabled
+//	-	32-bit system calls use i386 sizes -and- alignments
+//
+//	Note that this is NOT defined for the i386 native environment!
+//
+// __x86
+//	This is ONLY a synonym for defined(__i386) || defined(__amd64)
+//	which is useful only insofar as these two architectures share
+//	common attributes.  Analogous to __sparc.
+//
+// _PSM_MODULES
+//	This indicates whether or not the implementation uses PSM
+//	modules for processor support, reading /etc/mach from inside
+//	the kernel to extract a list.
+//
+// _RTC_CONFIG
+//	This indicates whether or not the implementation uses /etc/rtc_config
+//	to configure the real-time clock in the kernel.
+//
+// _UNIX_KRTLD
+//	This indicates that the implementation uses a dynamically

+// The feature test macros __XOPEN_OR_POSIX, _STRICT_STDC, _STRICT_SYMBOLS,
+// and _STDC_C99 are Sun implementation specific macros created in order to
+// compress common standards specified feature test macros for easier reading.
+// These macros should not be used by the application developer as
+// unexpected results may occur. Instead, the user should reference
+// standards(7) for correct usage of the standards feature test macros.
+//
+// __XOPEN_OR_POSIX     Used in cases where a symbol is defined by both
+//                      X/Open or POSIX or in the negative, when neither
+//                      X/Open or POSIX defines a symbol.
+//
+// _STRICT_STDC         __STDC__ is specified by the C Standards and defined
+//                      by the compiler. For Sun compilers the value of
+//                      __STDC__ is either 1, 0, or not defined based on the
+//                      compilation mode (see cc(1)). When the value of
+//                      __STDC__ is 1 and in the absence of any other feature
+//                      test macros, the namespace available to the application
+//                      is limited to only those symbols defined by the C
+//                      Standard. _STRICT_STDC provides a more readable means
+//                      of identifying symbols defined by the standard, or in
+//                      the negative, symbols that are extensions to the C
+//                      Standard. See additional comments for GNU C differences.
+//
+// _STDC_C99            __STDC_VERSION__ is specified by the C standards and
+//                      defined by the compiler and indicates the version of
+//                      the C standard. A value of 199901L indicates a
+//                      compiler that complies with ISO/IEC 9899:1999, other-
+//                      wise known as the C99 standard.
+//
+// _STDC_C11		Like _STDC_C99 except that the value of __STDC_VERSION__
+//                      is 201112L indicating a compiler that compiles with
+//                      ISO/IEC 9899:2011, otherwise known as the C11 standard.
+//
+// _STRICT_SYMBOLS	Used in cases where symbol visibility is restricted
+//                      by the standards, and the user has not explicitly
+//                      relaxed the strictness via __EXTENSIONS__.
+
+// ISO/IEC 9899:1990 and it's revisions, ISO/IEC 9899:1999 and ISO/IEC
+// 99899:2011 specify the following predefined macro name:
+//
+// __STDC__	The integer constant 1, intended to indicate a conforming
+//		implementation.
+//
+// Furthermore, a strictly conforming program shall use only those features
+// of the language and library specified in these standards. A conforming
+// implementation shall accept any strictly conforming program.
+//
+// Based on these requirements, Sun's C compiler defines __STDC__ to 1 for
+// strictly conforming environments and __STDC__ to 0 for environments that
+// use ANSI C semantics but allow extensions to the C standard. For non-ANSI
+// C semantics, Sun's C compiler does not define __STDC__.
+//
+// The GNU C project interpretation is that __STDC__ should always be defined
+// to 1 for compilation modes that accept ANSI C syntax regardless of whether
+// or not extensions to the C standard are used. Violations of conforming
+// behavior are conditionally flagged as warnings via the use of the
+// -pedantic option. In addition to defining __STDC__ to 1, the GNU C
+// compiler also defines __STRICT_ANSI__ as a means of specifying strictly
+// conforming environments using the -ansi or -std=<standard> options.
+//
+// In the absence of any other compiler options, Sun and GNU set the value
+// of __STDC__ as follows when using the following options:
+//
+//				Value of __STDC__  __STRICT_ANSI__
+//
+// cc -Xa (default)			0	      undefined
+// cc -Xt (transitional)		0             undefined
+// cc -Xc (strictly conforming)		1	      undefined
+// cc -Xs (K&R C)		    undefined	      undefined
+//
+// gcc (default)			1	      undefined
+// gcc -ansi, -std={c89, c99,...)	1               defined
+// gcc -traditional (K&R)	    undefined	      undefined
+//
+// The default compilation modes for Sun C compilers versus GNU C compilers
+// results in a differing value for __STDC__ which results in a more
+// restricted namespace when using Sun compilers. To allow both GNU and Sun
+// interpretations to peacefully co-exist, we use the following Sun
+// implementation _STRICT_STDC_ macro:
+
+// Compiler complies with ISO/IEC 9899:1999 or ISO/IEC 9989:2011
+
+// Use strict symbol visibility.
+
+// This is a variant of _STRICT_SYMBOLS that is meant to cover headers that are
+// governed by POSIX, but have not been governed by ISO C. One can go two ways
+// on what should happen if an application actively includes (not transitively)
+// a header that isn't part of the ISO C spec, we opt to say that if someone has
+// gone out of there way then they're doing it for a reason and that is an act
+// of non-compliance and therefore it's not up to us to hide away every symbol.
+//
+// In general, prefer using _STRICT_SYMBOLS, but this is here in particular for
+// cases where in the past we have only used a POSIX related check and we don't
+// wish to make something stricter. Often applications are relying on the
+// ability to, or more realistically unwittingly, have _STRICT_STDC declared and
+// still use these interfaces.
+
+// Large file interfaces:
+//
+//	_LARGEFILE_SOURCE
+//		1		large file-related additions to POSIX
+//				interfaces requested (fseeko, etc.)
+//	_LARGEFILE64_SOURCE
+//		1		transitional large-file-related interfaces
+//				requested (seek64, stat64, etc.)
+//
+// The corresponding announcement macros are respectively:
+//	_LFS_LARGEFILE
+//	_LFS64_LARGEFILE
+// (These are set in <unistd.h>.)
+//
+// Requesting _LARGEFILE64_SOURCE implies requesting _LARGEFILE_SOURCE as
+// well.
+//
+// The large file interfaces are made visible regardless of the initial values
+// of the feature test macros under certain circumstances:
+//    -	If no explicit standards-conforming environment is requested (neither
+//	of _POSIX_SOURCE nor _XOPEN_SOURCE is defined and the value of
+//	__STDC__ does not imply standards conformance).
+//    -	Extended system interfaces are explicitly requested (__EXTENSIONS__
+//	is defined).
+//    -	Access to in-kernel interfaces is requested (_KERNEL or _KMEMUSER is
+//	defined).  (Note that this dependency is an artifact of the current
+//	kernel implementation and may change in future releases.)
+
+// Large file compilation environment control:
+//
+// The setting of _FILE_OFFSET_BITS controls the size of various file-related
+// types and governs the mapping between file-related source function symbol
+// names and the corresponding binary entry points.
+//
+// In the 32-bit environment, the default value is 32; if not set, set it to
+// the default here, to simplify tests in other headers.
+//
+// In the 64-bit compilation environment, the only value allowed is 64.
+
+// Use of _XOPEN_SOURCE

+// Feature Test Macro				     Specification
+// ------------------------------------------------  -------------
+// _XOPEN_SOURCE                                         XPG3
+// _XOPEN_SOURCE && _XOPEN_VERSION = 4                   XPG4
+// _XOPEN_SOURCE && _XOPEN_SOURCE_EXTENDED = 1           XPG4v2
+// _XOPEN_SOURCE = 500                                   XPG5
+// _XOPEN_SOURCE = 600  (or POSIX_C_SOURCE=200112L)      XPG6

+//
+// In order to simplify the guards within the headers, the following
+// implementation private test macros have been created. Applications
+// must NOT use these private test macros as unexpected results will
+// occur.
+//
+// Note that in general, the use of these private macros is cumulative.
+// For example, the use of _XPG3 with no other restrictions on the X/Open
+// namespace will make the symbols visible for XPG3 through XPG6
+// compilation environments. The use of _XPG4_2 with no other X/Open
+// namespace restrictions indicates that the symbols were introduced in
+// XPG4v2 and are therefore visible for XPG4v2 through XPG6 compilation
+// environments, but not for XPG3 or XPG4 compilation environments.
+//
+// _XPG3    X/Open Portability Guide, Issue 3 (XPG3)
+// _XPG4    X/Open CAE Specification, Issue 4 (XPG4)
+// _XPG4_2  X/Open CAE Specification, Issue 4, Version 2 (XPG4v2/UNIX 95/SUS)
+// _XPG5    X/Open CAE Specification, Issue 5 (XPG5/UNIX 98/SUSv2)
+// _XPG6    Open Group Technical Standard, Issue 6 (XPG6/UNIX 03/SUSv3)
+// _XPG7    Open Group Technical Standard, Issue 7 (XPG7/UNIX 08/SUSv4)
+
+// X/Open Portability Guide, Issue 3
+
+// _XOPEN_VERSION is defined by the X/Open specifications and is not
+// normally defined by the application, except in the case of an XPG4
+// application.  On the implementation side, _XOPEN_VERSION defined with
+// the value of 3 indicates an XPG3 application. _XOPEN_VERSION defined
+// with the value of 4 indicates an XPG4 or XPG4v2 (UNIX 95) application.
+// _XOPEN_VERSION  defined with a value of 500 indicates an XPG5 (UNIX 98)
+// application and with a value of 600 indicates an XPG6 (UNIX 03)
+// application and with a value of 700 indicates an XPG7 (UNIX 08).
+// The appropriate version is determined by the use of the
+// feature test macros described earlier.  The value of _XOPEN_VERSION
+// defaults to 3 otherwise indicating support for XPG3 applications.
+
+// ANSI C and ISO 9899:1990 say the type long long doesn't exist in strictly
+// conforming environments.  ISO 9899:1999 says it does.
+//
+// The presence of _LONGLONG_TYPE says "long long exists" which is therefore
+// defined in all but strictly conforming environments that disallow it.
+
+// The following macro defines a value for the ISO C99 restrict
+// keyword so that _RESTRICT_KYWD resolves to "restrict" if
+// an ISO C99 compiler is used, "__restrict" for c++ and "" (null string)
+// if any other compiler is used. This allows for the use of single
+// prototype declarations regardless of compiler version.
+
+// The following macro defines a value for the ISO C11 _Noreturn
+// keyword so that _NORETURN_KYWD resolves to "_Noreturn" if
+// an ISO C11 compiler is used and "" (null string) if any other
+// compiler is used. This allows for the use of single prototype
+// declarations regardless of compiler version.

+//    only for compatibility.  All new code should use the other symbols
+//    to test for features.
+//
+//    All macros listed above as possibly being defined by this file are
+//    explicitly undefined if they are not explicitly defined.
+//    Feature-test macros that are not defined by the user or compiler
+//    but are implied by the other feature-test macros defined (or by the
+//    lack of any definitions) are defined by the file.
+//
+//    ISO C feature test macros depend on the definition of the macro
+//    when an affected header is included, not when the first system
+//    header is included, and so they are handled in
+//    <bits/libc-header-start.h>, which does not have a multiple include
+//    guard.  Feature test macros that can be handled from the first

+//    #endif
+//    Note: only works for GCC 2.0 and later, because __GNUC_MINOR__ was
+//    added in 2.0.
+
+// Similarly for clang.  Features added to GCC after version 4.2 may
+//    or may not also be available in clang, and clang's definitions of

+//    issue a warning; the expectation is that the source is being
+//    transitioned to use the new macro.
+
+// If _GNU_SOURCE was defined by the user, turn on all the other features.
+
+// If nothing (other than _GNU_SOURCE and _DEFAULT_SOURCE) is defined,

+
+// If none of the ANSI/POSIX macros are defined, or if _DEFAULT_SOURCE
+//    is defined, use POSIX.1-2008 (or another version depending on
+//    _XOPEN_SOURCE).
+
+// Some C libraries once required _REENTRANT and/or _THREAD_SAFE to be
+//    defined in all multithreaded code.  GNU libc has not required this
+//    for many years.  We now treat them as compatibility synonyms for
+//    _POSIX_C_SOURCE=199506L, which is the earliest level of POSIX with
+//    comprehensive support for multithreaded code.  Using them never
+//    lowers the selected level of POSIX conformance, only raises it.
+
+// The function 'gets' existed in C89, but is impossible to use
+//    safely.  It has been removed from ISO C11 and ISO C++14.  Note: for
+//    compatibility with various implementations of <cstdio>, this test
+//    must consider only the value of __cplusplus when compiling C++.
+
+// GNU formerly extended the scanf functions with modified format
+//    specifiers %as, %aS, and %a[...] that allocate a buffer for the
+//    input using malloc.  This extension conflicts with ISO C99, which
+//    defines %a as a standalone format specifier that reads a floating-
+//    point number; moreover, POSIX.1-2008 provides the same feature
+//    using the modifier letter 'm' instead (%ms, %mS, %m[...]).
+//
+//    We now follow C99 unless GNU extensions are active and the compiler
+//    is specifically in C89 or C++98 mode (strict or not).  For
+//    instance, with GCC, -std=gnu11 will have C99-compliant scanf with
+//    or without -D_GNU_SOURCE, but -std=c89 -D_GNU_SOURCE will have the
+//    old extension.

+// We are almost always included from features.h.
+
+// The GNU libc does not support any K&R compilers or the traditional mode
+//    of ISO C compilers anymore.  Check for some of the combinations not
+//    anymore supported.
+
+// Some user header file might have defined this before.
+
+// All functions, except those with callbacks or those that
+//    synchronize memory, are leaf functions.
+
+// GCC can always grok prototypes.  For C++ programs we add throw()
+//    to help it optimize the function calls.  But this works only with
+//    gcc 2.8.x and egcs.  For gcc 3.2 and up we even mark C functions
+//    as non-throwing using a function attribute since programs can use
+//    the -fexceptions options for C code as well.
+
+// Compilers that are not clang may object to
+//        #if defined __clang__ && __has_extension(...)
+//    even though they do not need to evaluate the right-hand side of the &&.
+
+// These two macros are not used in glibc anymore.  They are kept here
+//    only because some other projects expect the macros to be defined.
+
+// For these things, GCC behaves the ANSI way normally,
+//    and the non-ANSI way under -traditional.
+
+// This is not a typedef so `const __ptr_t' does the right thing.
+
+// C++ needs to know that types and declarations are C, not C++.
+
+// Fortify support.
+
+// Support for flexible arrays.
+//    Headers that should use flexible arrays only if they're "real"
+//    (e.g. only if they won't affect sizeof()) should test
+//    #if __glibc_c99_flexarr_available.
+
+// __asm__ ("xyz") is used throughout the headers to rename functions
+//    at the assembly language level.  This is wrapped by the __REDIRECT
+//    macro, in order to support compilers that can do this some other
+//    way.  When compilers don't support asm-names at all, we have to do
+//    preprocessor tricks instead (which don't have exactly the right
+//    semantics, but it's the best we can do).
+//
+//    Example:
+//    int __REDIRECT(setpgrp, (__pid_t pid, __pid_t pgrp), setpgid);
+
+//
+// #elif __SOME_OTHER_COMPILER__
+//
+// # define __REDIRECT(name, proto, alias) name proto; 	_Pragma("let " #name " = " #alias)
+
+// GCC has various useful declarations that can be made with the
+//    `__attribute__' syntax.  All of the ways we use this do fine if
+//    they are omitted for compilers that don't understand it.
+
+// At some point during the gcc 2.96 development the `malloc' attribute
+//    for functions was introduced.  We don't want to use it unconditionally
+//    (although this would be possible) since it generates warnings.
+
+// Tell the compiler which arguments to an allocation function
+//    indicate the size of the allocation.
+
+// At some point during the gcc 2.96 development the `pure' attribute
+//    for functions was introduced.  We don't want to use it unconditionally
+//    (although this would be possible) since it generates warnings.
+
+// This declaration tells the compiler that the value is constant.
+
+// At some point during the gcc 3.1 development the `used' attribute
+//    for functions was introduced.  We don't want to use it unconditionally
+//    (although this would be possible) since it generates warnings.
+
+// Since version 3.2, gcc allows marking deprecated functions.
+
+// Since version 4.5, gcc also allows one to specify the message printed
+//    when a deprecated function is used.  clang claims to be gcc 4.2, but
+//    may also support this feature.
+
+// At some point during the gcc 2.8 development the `format_arg' attribute
+//    for functions was introduced.  We don't want to use it unconditionally
+//    (although this would be possible) since it generates warnings.
+//    If several `format_arg' attributes are given for the same function, in
+//    gcc-3.0 and older, all but the last one are ignored.  In newer gccs,
+//    all designated arguments are considered.
+
+// At some point during the gcc 2.97 development the `strfmon' format
+//    attribute for functions was introduced.  We don't want to use it
+//    unconditionally (although this would be possible) since it
+//    generates warnings.
+
+// The nonull function attribute allows to mark pointer parameters which
+//    must not be NULL.
+
+// If fortification mode, we warn about unused results of certain
+//    function calls which can lead to problems.
+
+// Forces a function to be always inlined.
+// The Linux kernel defines __always_inline in stddef.h (283d7573), and
+//    it conflicts with this definition.  Therefore undefine it first to
+//    allow either header to be included first.
+
+// Associate error messages with the source location of the call site rather
+//    than with the source location inside the function.
+
+// GCC 4.3 and above with -std=c99 or -std=gnu99 implements ISO C99
+//    inline semantics, unless -fgnu89-inline is used.  Using __GNUC_STDC_INLINE__
+//    or __GNUC_GNU_INLINE is not a good enough check for gcc because gcc versions
+//    older than 4.3 may define these macros and still not guarantee GNU inlining
+//    semantics.
+//
+//    clang++ identifies itself as gcc-4.2, but has support for GNU inlining
+//    semantics, that can be checked for by using the __GNUC_STDC_INLINE_ and
+//    __GNUC_GNU_INLINE__ macro definitions.
+
+// GCC 4.3 and above allow passing all anonymous arguments of an
+//    __extern_always_inline function to some other vararg function.
+
+// It is possible to compile containing GCC extensions even if GCC is
+//    run in pedantic mode if the uses are carefully marked using the
+//    `__extension__' keyword.  But this is not generally available before
+//    version 2.8.
+
+// __restrict is known in EGCS 1.2 and above.

+// 	16		-- "natural" 16-bit type (always short)

+//
+//    Here we assume what is presently the case in all the GCC configurations

+//
+//    These are defined by this file and are used by the

+//    __GLIBC_USE (F)	Define things from feature set F.  This is defined

+//    __USE_ISOC95		Define ISO C90 AMD1 (C95) things.
+//    __USE_ISOCXX11	Define ISO C++11 things.

+//    __USE_POSIX199309	Define IEEE Std 1003.1, and .1b things.

+//    __USE_MISC		Define things from 4.3BSD or System V Unix.
+//    __USE_ATFILE		Define *at interfaces and AT_* constants for them.
+//    __USE_GNU		Define GNU extensions.
+//    __USE_FORTIFY_LEVEL	Additional security measures used, according to level.
+//
+//    The macros `__GNU_LIBRARY__', `__GLIBC__', and `__GLIBC_MINOR__' are
+//    defined by this file unconditionally.  `__GNU_LIBRARY__' is provided
+//    only for compatibility.  All new code should use the other symbols
+//    to test for features.
+//
+//    All macros listed above as possibly being defined by this file are
+//    explicitly undefined if they are not explicitly defined.
+//    Feature-test macros that are not defined by the user or compiler
+//    but are implied by the other feature-test macros defined (or by the
+//    lack of any definitions) are defined by the file.
+//
+//    ISO C feature test macros depend on the definition of the macro
+//    when an affected header is included, not when the first system
+//    header is included, and so they are handled in
+//    <bits/libc-header-start.h>, which does not have a multiple include
+//    guard.  Feature test macros that can be handled from the first
+//    system header included are handled here.
+
+// Undefine everything, so we get a clean slate.
+
+// Suppress kernel-name space pollution unless user expressedly asks
+//    for it.
+
+// Convenience macro to test the version of gcc.
+//    Use like this:
+//    #if __GNUC_PREREQ (2,8)
+//    ... code requiring gcc 2.8 or later ...
+//    #endif
+//    Note: only works for GCC 2.0 and later, because __GNUC_MINOR__ was
+//    added in 2.0.
+
+// Similarly for clang.  Features added to GCC after version 4.2 may
+//    or may not also be available in clang, and clang's definitions of
+//    __GNUC(_MINOR)__ are fixed at 4 and 2 respectively.  Not all such
+//    features can be queried via __has_extension/__has_feature.
+
+// Whether to use feature set F.
+
+// _BSD_SOURCE and _SVID_SOURCE are deprecated aliases for
+//    _DEFAULT_SOURCE.  If _DEFAULT_SOURCE is present we do not
+//    issue a warning; the expectation is that the source is being
+//    transitioned to use the new macro.
+
+// If _GNU_SOURCE was defined by the user, turn on all the other features.
+
+// If nothing (other than _GNU_SOURCE and _DEFAULT_SOURCE) is defined,
+//    define _DEFAULT_SOURCE.
+
+// This is to enable the ISO C2X extension.
+
+// This is to enable the ISO C11 extension.
+
+// This is to enable the ISO C99 extension.
+
+// This is to enable the ISO C90 Amendment 1:1995 extension.
+
+// If none of the ANSI/POSIX macros are defined, or if _DEFAULT_SOURCE
+//    is defined, use POSIX.1-2008 (or another version depending on
+//    _XOPEN_SOURCE).
+
+// Some C libraries once required _REENTRANT and/or _THREAD_SAFE to be
+//    defined in all multithreaded code.  GNU libc has not required this
+//    for many years.  We now treat them as compatibility synonyms for
+//    _POSIX_C_SOURCE=199506L, which is the earliest level of POSIX with
+//    comprehensive support for multithreaded code.  Using them never
+//    lowers the selected level of POSIX conformance, only raises it.
+
+// The function 'gets' existed in C89, but is impossible to use
+//    safely.  It has been removed from ISO C11 and ISO C++14.  Note: for
+//    compatibility with various implementations of <cstdio>, this test
+//    must consider only the value of __cplusplus when compiling C++.
+
+// GNU formerly extended the scanf functions with modified format
+//    specifiers %as, %aS, and %a[...] that allocate a buffer for the
+//    input using malloc.  This extension conflicts with ISO C99, which
+//    defines %a as a standalone format specifier that reads a floating-
+//    point number; moreover, POSIX.1-2008 provides the same feature
+//    using the modifier letter 'm' instead (%ms, %mS, %m[...]).
+//
+//    We now follow C99 unless GNU extensions are active and the compiler
+//    is specifically in C89 or C++98 mode (strict or not).  For
+//    instance, with GCC, -std=gnu11 will have C99-compliant scanf with
+//    or without -D_GNU_SOURCE, but -std=c89 -D_GNU_SOURCE will have the
+//    old extension.

+
+// Compilers that are not clang may object to

+
+// These two macros are not used in glibc anymore.  They are kept here
+//    only because some other projects expect the macros to be defined.
+
+// For these things, GCC behaves the ANSI way normally,
+//    and the non-ANSI way under -traditional.
+
+// This is not a typedef so `const __ptr_t' does the right thing.
+
+// C++ needs to know that types and declarations are C, not C++.
+
+// Fortify support.
+
+// Support for flexible arrays.
+//    Headers that should use flexible arrays only if they're "real"
+//    (e.g. only if they won't affect sizeof()) should test
+//    #if __glibc_c99_flexarr_available.
+
+// __asm__ ("xyz") is used throughout the headers to rename functions
+//    at the assembly language level.  This is wrapped by the __REDIRECT
+//    macro, in order to support compilers that can do this some other
+//    way.  When compilers don't support asm-names at all, we have to do
+//    preprocessor tricks instead (which don't have exactly the right
+//    semantics, but it's the best we can do).
+//
+//    Example:
+//    int __REDIRECT(setpgrp, (__pid_t pid, __pid_t pgrp), setpgid);
+
+//
+// #elif __SOME_OTHER_COMPILER__
+//
+// # define __REDIRECT(name, proto, alias) name proto; 	_Pragma("let " #name " = " #alias)
+
+// GCC has various useful declarations that can be made with the
+//    `__attribute__' syntax.  All of the ways we use this do fine if
+//    they are omitted for compilers that don't understand it.
+
+// At some point during the gcc 2.96 development the `malloc' attribute
+//    for functions was introduced.  We don't want to use it unconditionally
+//    (although this would be possible) since it generates warnings.
+
+// Tell the compiler which arguments to an allocation function
+//    indicate the size of the allocation.
+
+// At some point during the gcc 2.96 development the `pure' attribute
+//    for functions was introduced.  We don't want to use it unconditionally
+//    (although this would be possible) since it generates warnings.
+
+// This declaration tells the compiler that the value is constant.
+
+// At some point during the gcc 3.1 development the `used' attribute
+//    for functions was introduced.  We don't want to use it unconditionally
+//    (although this would be possible) since it generates warnings.
+
+// Since version 3.2, gcc allows marking deprecated functions.
+
+// Since version 4.5, gcc also allows one to specify the message printed
+//    when a deprecated function is used.  clang claims to be gcc 4.2, but
+//    may also support this feature.
+
+// At some point during the gcc 2.8 development the `format_arg' attribute
+//    for functions was introduced.  We don't want to use it unconditionally
+//    (although this would be possible) since it generates warnings.
+//    If several `format_arg' attributes are given for the same function, in
+//    gcc-3.0 and older, all but the last one are ignored.  In newer gccs,
+//    all designated arguments are considered.
+
+// At some point during the gcc 2.97 development the `strfmon' format
+//    attribute for functions was introduced.  We don't want to use it
+//    unconditionally (although this would be possible) since it
+//    generates warnings.
+
+// The nonull function attribute allows to mark pointer parameters which
+//    must not be NULL.
+
+// If fortification mode, we warn about unused results of certain
+//    function calls which can lead to problems.
+
+// Forces a function to be always inlined.
+// The Linux kernel defines __always_inline in stddef.h (283d7573), and
+//    it conflicts with this definition.  Therefore undefine it first to
+//    allow either header to be included first.
+
+// Associate error messages with the source location of the call site rather
+//    than with the source location inside the function.
+
+// GCC 4.3 and above with -std=c99 or -std=gnu99 implements ISO C99
+//    inline semantics, unless -fgnu89-inline is used.  Using __GNUC_STDC_INLINE__
+//    or __GNUC_GNU_INLINE is not a good enough check for gcc because gcc versions
+//    older than 4.3 may define these macros and still not guarantee GNU inlining
+//    semantics.
+//
+//    clang++ identifies itself as gcc-4.2, but has support for GNU inlining
+//    semantics, that can be checked for by using the __GNUC_STDC_INLINE_ and
+//    __GNUC_GNU_INLINE__ macro definitions.
+
+// GCC 4.3 and above allow passing all anonymous arguments of an
+//    __extern_always_inline function to some other vararg function.
+
+// It is possible to compile containing GCC extensions even if GCC is
+//    run in pedantic mode if the uses are carefully marked using the
+//    `__extension__' keyword.  But this is not generally available before
+//    version 2.8.
+
+// __restrict is known in EGCS 1.2 and above.
+
+// ISO C99 also allows to declare arrays as non-overlapping.  The syntax is

+//
+//    ISO C feature test macros depend on the definition of the macro

+//    header is included, and so they are handled in
+//    <bits/libc-header-start.h>, which does not have a multiple include

+

+//    _XOPEN_SOURCE).
+
+// Some C libraries once required _REENTRANT and/or _THREAD_SAFE to be
+//    defined in all multithreaded code.  GNU libc has not required this
+//    for many years.  We now treat them as compatibility synonyms for
+//    _POSIX_C_SOURCE=199506L, which is the earliest level of POSIX with
+//    comprehensive support for multithreaded code.  Using them never
+//    lowers the selected level of POSIX conformance, only raises it.

+// The function 'gets' existed in C89, but is impossible to use
+//    safely.  It has been removed from ISO C11 and ISO C++14.  Note: for
+//    compatibility with various implementations of <cstdio>, this test
+//    must consider only the value of __cplusplus when compiling C++.
+
+// GNU formerly extended the scanf functions with modified format
+//    specifiers %as, %aS, and %a[...] that allocate a buffer for the
+//    input using malloc.  This extension conflicts with ISO C99, which
+//    defines %a as a standalone format specifier that reads a floating-
+//    point number; moreover, POSIX.1-2008 provides the same feature
+//    using the modifier letter 'm' instead (%ms, %mS, %m[...]).
+//
+//    We now follow C99 unless GNU extensions are active and the compiler
+//    is specifically in C89 or C++98 mode (strict or not).  For
+//    instance, with GCC, -std=gnu11 will have C99-compliant scanf with
+//    or without -D_GNU_SOURCE, but -std=c89 -D_GNU_SOURCE will have the
+//    old extension.

+// We are almost always included from features.h.
+
+// The GNU libc does not support any K&R compilers or the traditional mode
+//    of ISO C compilers anymore.  Check for some of the combinations not
+//    anymore supported.
+
+// Some user header file might have defined this before.
+
+// All functions, except those with callbacks or those that
+//    synchronize memory, are leaf functions.
+
+// GCC can always grok prototypes.  For C++ programs we add throw()
+//    to help it optimize the function calls.  But this works only with
+//    gcc 2.8.x and egcs.  For gcc 3.2 and up we even mark C functions
+//    as non-throwing using a function attribute since programs can use
+//    the -fexceptions options for C code as well.
+
+// Compilers that are not clang may object to
+//        #if defined __clang__ && __has_extension(...)
+//    even though they do not need to evaluate the right-hand side of the &&.
+
+// These two macros are not used in glibc anymore.  They are kept here
+//    only because some other projects expect the macros to be defined.
+
+// For these things, GCC behaves the ANSI way normally,
+//    and the non-ANSI way under -traditional.
+
+// This is not a typedef so `const __ptr_t' does the right thing.
+
+// C++ needs to know that types and declarations are C, not C++.
+
+// Fortify support.
+
+// Support for flexible arrays.
+//    Headers that should use flexible arrays only if they're "real"
+//    (e.g. only if they won't affect sizeof()) should test
+//    #if __glibc_c99_flexarr_available.
+
+// __asm__ ("xyz") is used throughout the headers to rename functions
+//    at the assembly language level.  This is wrapped by the __REDIRECT
+//    macro, in order to support compilers that can do this some other
+//    way.  When compilers don't support asm-names at all, we have to do
+//    preprocessor tricks instead (which don't have exactly the right
+//    semantics, but it's the best we can do).
+//
+//    Example:
+//    int __REDIRECT(setpgrp, (__pid_t pid, __pid_t pgrp), setpgid);
+
+//
+// #elif __SOME_OTHER_COMPILER__
+//
+// # define __REDIRECT(name, proto, alias) name proto; 	_Pragma("let " #name " = " #alias)
+
+// GCC has various useful declarations that can be made with the
+//    `__attribute__' syntax.  All of the ways we use this do fine if
+//    they are omitted for compilers that don't understand it.
+
+// At some point during the gcc 2.96 development the `malloc' attribute
+//    for functions was introduced.  We don't want to use it unconditionally
+//    (although this would be possible) since it generates warnings.
+
+// Tell the compiler which arguments to an allocation function
+//    indicate the size of the allocation.
+
+// At some point during the gcc 2.96 development the `pure' attribute
+//    for functions was introduced.  We don't want to use it unconditionally
+//    (although this would be possible) since it generates warnings.
+
+// This declaration tells the compiler that the value is constant.
+
+// At some point during the gcc 3.1 development the `used' attribute
+//    for functions was introduced.  We don't want to use it unconditionally
+//    (although this would be possible) since it generates warnings.
+
+// Since version 3.2, gcc allows marking deprecated functions.
+
+// Since version 4.5, gcc also allows one to specify the message printed
+//    when a deprecated function is used.  clang claims to be gcc 4.2, but
+//    may also support this feature.
+
+// At some point during the gcc 2.8 development the `format_arg' attribute
+//    for functions was introduced.  We don't want to use it unconditionally
+//    (although this would be possible) since it generates warnings.
+//    If several `format_arg' attributes are given for the same function, in
+//    gcc-3.0 and older, all but the last one are ignored.  In newer gccs,
+//    all designated arguments are considered.
+
+// At some point during the gcc 2.97 development the `strfmon' format
+//    attribute for functions was introduced.  We don't want to use it
+//    unconditionally (although this would be possible) since it
+//    generates warnings.
+
+// The nonull function attribute allows to mark pointer parameters which
+//    must not be NULL.
+
+// If fortification mode, we warn about unused results of certain
+//    function calls which can lead to problems.
+
+// Forces a function to be always inlined.
+// The Linux kernel defines __always_inline in stddef.h (283d7573), and
+//    it conflicts with this definition.  Therefore undefine it first to
+//    allow either header to be included first.
+
+// Associate error messages with the source location of the call site rather
+//    than with the source location inside the function.
+
+// GCC 4.3 and above with -std=c99 or -std=gnu99 implements ISO C99
+//    inline semantics, unless -fgnu89-inline is used.  Using __GNUC_STDC_INLINE__
+//    or __GNUC_GNU_INLINE is not a good enough check for gcc because gcc versions
+//    older than 4.3 may define these macros and still not guarantee GNU inlining
+//    semantics.
+//
+//    clang++ identifies itself as gcc-4.2, but has support for GNU inlining
+//    semantics, that can be checked for by using the __GNUC_STDC_INLINE_ and
+//    __GNUC_GNU_INLINE__ macro definitions.
+
+// GCC 4.3 and above allow passing all anonymous arguments of an
+//    __extern_always_inline function to some other vararg function.
+
+// It is possible to compile containing GCC extensions even if GCC is
+//    run in pedantic mode if the uses are carefully marked using the
+//    `__extension__' keyword.  But this is not generally available before
+//    version 2.8.
+
+// __restrict is known in EGCS 1.2 and above.
+
+// ISO C99 also allows to declare arrays as non-overlapping.  The syntax is
+//      array_name[restrict]
+//    GCC 3.1 supports this.

+// The machine-dependent file <bits/typesizes.h> defines __*_T_TYPE
+//    macros for each of the OS types we define below.  The definitions
+//    of those macros must use the following macros for underlying types.
+//    We define __S<SIZE>_TYPE and __U<SIZE>_TYPE for the signed and unsigned
+//    variants of each of the following integer types on this machine.
+//
+// 	16		-- "natural" 16-bit type (always short)
+// 	32		-- "natural" 32-bit type (always int)
+// 	64		-- "natural" 64-bit type (long or long long)
+// 	LONG32		-- 32-bit type, traditionally long
+// 	QUAD		-- 64-bit type, traditionally long long
+// 	WORD		-- natural type of __WORDSIZE bits (int or long)
+// 	LONGWORD	-- type of __WORDSIZE bits, traditionally long
+//
+//    We distinguish WORD/LONGWORD, 32/LONG32, and 64/QUAD so that the
+//    conventional uses of `long' or `long long' type modifiers match the
+//    types we define, even when a less-adorned type would be the same size.
+//    This matters for (somewhat) portably writing printf/scanf formats for
+//    these types, where using the appropriate l or ll format modifiers can
+//    make the typedefs and the formats match up across all GNU platforms.  If
+//    we used `long' when it's 64 bits where `long long' is expected, then the
+//    compiler would warn about the formats not matching the argument types,
+//    and the programmer changing them to shut up the compiler would break the
+//    program's portability.
+//
+//    Here we assume what is presently the case in all the GCC configurations
+//    we support: long long is always 64 bits, long is always word/address size,
+//    and int is always 32 bits.
+
+// We want __extension__ before typedef's that use nonstandard base types
+//    such as `long long' in C89 mode.

+//
+//    These are defined by this file and are used by the

+//
+//    __GLIBC_USE (F)	Define things from feature set F.  This is defined

+//    __USE_POSIX199309	Define IEEE Std 1003.1, and .1b things.

+//    __USE_FILE_OFFSET64	Define 64bit interface as default.
+//    __USE_MISC		Define things from 4.3BSD or System V Unix.
+//    __USE_ATFILE		Define *at interfaces and AT_* constants for them.
+//    __USE_GNU		Define GNU extensions.
+//    __USE_FORTIFY_LEVEL	Additional security measures used, according to level.
+//
+//    The macros `__GNU_LIBRARY__', `__GLIBC__', and `__GLIBC_MINOR__' are
+//    defined by this file unconditionally.  `__GNU_LIBRARY__' is provided
+//    only for compatibility.  All new code should use the other symbols
+//    to test for features.
+//
+//    All macros listed above as possibly being defined by this file are
+//    explicitly undefined if they are not explicitly defined.
+//    Feature-test macros that are not defined by the user or compiler
+//    but are implied by the other feature-test macros defined (or by the
+//    lack of any definitions) are defined by the file.
+//
+//    ISO C feature test macros depend on the definition of the macro
+//    when an affected header is included, not when the first system
+//    header is included, and so they are handled in
+//    <bits/libc-header-start.h>, which does not have a multiple include
+//    guard.  Feature test macros that can be handled from the first
+//    system header included are handled here.
+
+// Undefine everything, so we get a clean slate.
+
+// Suppress kernel-name space pollution unless user expressedly asks
+//    for it.
+
+// Convenience macro to test the version of gcc.
+//    Use like this:
+//    #if __GNUC_PREREQ (2,8)
+//    ... code requiring gcc 2.8 or later ...
+//    #endif
+//    Note: only works for GCC 2.0 and later, because __GNUC_MINOR__ was
+//    added in 2.0.
+
+// Similarly for clang.  Features added to GCC after version 4.2 may
+//    or may not also be available in clang, and clang's definitions of
+//    __GNUC(_MINOR)__ are fixed at 4 and 2 respectively.  Not all such
+//    features can be queried via __has_extension/__has_feature.
+
+// Whether to use feature set F.
+
+// _BSD_SOURCE and _SVID_SOURCE are deprecated aliases for
+//    _DEFAULT_SOURCE.  If _DEFAULT_SOURCE is present we do not
+//    issue a warning; the expectation is that the source is being
+//    transitioned to use the new macro.
+
+// If _GNU_SOURCE was defined by the user, turn on all the other features.
+
+// If nothing (other than _GNU_SOURCE and _DEFAULT_SOURCE) is defined,
+//    define _DEFAULT_SOURCE.
+
+// This is to enable the ISO C2X extension.
+
+// This is to enable the ISO C11 extension.
+
+// This is to enable the ISO C99 extension.
+
+// This is to enable the ISO C90 Amendment 1:1995 extension.
+
+// If none of the ANSI/POSIX macros are defined, or if _DEFAULT_SOURCE
+//    is defined, use POSIX.1-2008 (or another version depending on
+//    _XOPEN_SOURCE).
+
+// Some C libraries once required _REENTRANT and/or _THREAD_SAFE to be
+//    defined in all multithreaded code.  GNU libc has not required this
+//    for many years.  We now treat them as compatibility synonyms for
+//    _POSIX_C_SOURCE=199506L, which is the earliest level of POSIX with
+//    comprehensive support for multithreaded code.  Using them never
+//    lowers the selected level of POSIX conformance, only raises it.
+
+// The function 'gets' existed in C89, but is impossible to use
+//    safely.  It has been removed from ISO C11 and ISO C++14.  Note: for
+//    compatibility with various implementations of <cstdio>, this test
+//    must consider only the value of __cplusplus when compiling C++.
+
+// GNU formerly extended the scanf functions with modified format
+//    specifiers %as, %aS, and %a[...] that allocate a buffer for the
+//    input using malloc.  This extension conflicts with ISO C99, which
+//    defines %a as a standalone format specifier that reads a floating-
+//    point number; moreover, POSIX.1-2008 provides the same feature
+//    using the modifier letter 'm' instead (%ms, %mS, %m[...]).
+//
+//    We now follow C99 unless GNU extensions are active and the compiler
+//    is specifically in C89 or C++98 mode (strict or not).  For
+//    instance, with GCC, -std=gnu11 will have C99-compliant scanf with
+//    or without -D_GNU_SOURCE, but -std=c89 -D_GNU_SOURCE will have the
+//    old extension.

+// The GNU libc does not support any K&R compilers or the traditional mode
+//    of ISO C compilers anymore.  Check for some of the combinations not
+//    anymore supported.
+
+// Some user header file might have defined this before.
+
+// All functions, except those with callbacks or those that
+//    synchronize memory, are leaf functions.
+
+// GCC can always grok prototypes.  For C++ programs we add throw()
+//    to help it optimize the function calls.  But this works only with
+//    gcc 2.8.x and egcs.  For gcc 3.2 and up we even mark C functions
+//    as non-throwing using a function attribute since programs can use
+//    the -fexceptions options for C code as well.
+
+// Compilers that are not clang may object to
+//        #if defined __clang__ && __has_extension(...)
+//    even though they do not need to evaluate the right-hand side of the &&.
+
+// These two macros are not used in glibc anymore.  They are kept here
+//    only because some other projects expect the macros to be defined.
+
+// For these things, GCC behaves the ANSI way normally,
+//    and the non-ANSI way under -traditional.
+
+// This is not a typedef so `const __ptr_t' does the right thing.
+
+// C++ needs to know that types and declarations are C, not C++.
+
+// Fortify support.
+
+// Support for flexible arrays.
+//    Headers that should use flexible arrays only if they're "real"
+//    (e.g. only if they won't affect sizeof()) should test
+//    #if __glibc_c99_flexarr_available.
+
+// __asm__ ("xyz") is used throughout the headers to rename functions
+//    at the assembly language level.  This is wrapped by the __REDIRECT
+//    macro, in order to support compilers that can do this some other
+//    way.  When compilers don't support asm-names at all, we have to do
+//    preprocessor tricks instead (which don't have exactly the right
+//    semantics, but it's the best we can do).
+//
+//    Example:
+//    int __REDIRECT(setpgrp, (__pid_t pid, __pid_t pgrp), setpgid);
+
+//
+// #elif __SOME_OTHER_COMPILER__
+//
+// # define __REDIRECT(name, proto, alias) name proto; 	_Pragma("let " #name " = " #alias)
+
+// GCC has various useful declarations that can be made with the
+//    `__attribute__' syntax.  All of the ways we use this do fine if
+//    they are omitted for compilers that don't understand it.
+
+// At some point during the gcc 2.96 development the `malloc' attribute
+//    for functions was introduced.  We don't want to use it unconditionally
+//    (although this would be possible) since it generates warnings.
+
+// Tell the compiler which arguments to an allocation function
+//    indicate the size of the allocation.
+
+// At some point during the gcc 2.96 development the `pure' attribute
+//    for functions was introduced.  We don't want to use it unconditionally
+//    (although this would be possible) since it generates warnings.
+
+// This declaration tells the compiler that the value is constant.
+
+// At some point during the gcc 3.1 development the `used' attribute
+//    for functions was introduced.  We don't want to use it unconditionally
+//    (although this would be possible) since it generates warnings.
+
+// Since version 3.2, gcc allows marking deprecated functions.
+
+// Since version 4.5, gcc also allows one to specify the message printed
+//    when a deprecated function is used.  clang claims to be gcc 4.2, but
+//    may also support this feature.
+
+// At some point during the gcc 2.8 development the `format_arg' attribute
+//    for functions was introduced.  We don't want to use it unconditionally
+//    (although this would be possible) since it generates warnings.
+//    If several `format_arg' attributes are given for the same function, in
+//    gcc-3.0 and older, all but the last one are ignored.  In newer gccs,
+//    all designated arguments are considered.
+
+// At some point during the gcc 2.97 development the `strfmon' format
+//    attribute for functions was introduced.  We don't want to use it
+//    unconditionally (although this would be possible) since it
+//    generates warnings.
+
+// The nonull function attribute allows to mark pointer parameters which
+//    must not be NULL.
+
+// If fortification mode, we warn about unused results of certain
+//    function calls which can lead to problems.
+
+// Forces a function to be always inlined.
+// The Linux kernel defines __always_inline in stddef.h (283d7573), and
+//    it conflicts with this definition.  Therefore undefine it first to
+//    allow either header to be included first.
+
+// Associate error messages with the source location of the call site rather
+//    than with the source location inside the function.
+
+// GCC 4.3 and above with -std=c99 or -std=gnu99 implements ISO C99
+//    inline semantics, unless -fgnu89-inline is used.  Using __GNUC_STDC_INLINE__
+//    or __GNUC_GNU_INLINE is not a good enough check for gcc because gcc versions
+//    older than 4.3 may define these macros and still not guarantee GNU inlining
+//    semantics.
+//
+//    clang++ identifies itself as gcc-4.2, but has support for GNU inlining
+//    semantics, that can be checked for by using the __GNUC_STDC_INLINE_ and
+//    __GNUC_GNU_INLINE__ macro definitions.
+
+// GCC 4.3 and above allow passing all anonymous arguments of an
+//    __extern_always_inline function to some other vararg function.

+//    We define __S<SIZE>_TYPE and __U<SIZE>_TYPE for the signed and unsigned

+//
+// 	16		-- "natural" 16-bit type (always short)

+// 	64		-- "natural" 64-bit type (long or long long)
+// 	LONG32		-- 32-bit type, traditionally long
+// 	QUAD		-- 64-bit type, traditionally long long
+// 	WORD		-- natural type of __WORDSIZE bits (int or long)
+// 	LONGWORD	-- type of __WORDSIZE bits, traditionally long
+//
+//    We distinguish WORD/LONGWORD, 32/LONG32, and 64/QUAD so that the
+//    conventional uses of `long' or `long long' type modifiers match the
+//    types we define, even when a less-adorned type would be the same size.
+//    This matters for (somewhat) portably writing printf/scanf formats for
+//    these types, where using the appropriate l or ll format modifiers can
+//    make the typedefs and the formats match up across all GNU platforms.  If
+//    we used `long' when it's 64 bits where `long long' is expected, then the
+//    compiler would warn about the formats not matching the argument types,
+//    and the programmer changing them to shut up the compiler would break the
+//    program's portability.
+//
+//    Here we assume what is presently the case in all the GCC configurations
+//    we support: long long is always 64 bits, long is always word/address size,
+//    and int is always 32 bits.

+//
+//    The macros `__GNU_LIBRARY__', `__GLIBC__', and `__GLIBC_MINOR__' are
+//    defined by this file unconditionally.  `__GNU_LIBRARY__' is provided
+//    only for compatibility.  All new code should use the other symbols
+//    to test for features.
+//
+//    All macros listed above as possibly being defined by this file are
+//    explicitly undefined if they are not explicitly defined.
+//    Feature-test macros that are not defined by the user or compiler
+//    but are implied by the other feature-test macros defined (or by the
+//    lack of any definitions) are defined by the file.
+//
+//    ISO C feature test macros depend on the definition of the macro
+//    when an affected header is included, not when the first system
+//    header is included, and so they are handled in
+//    <bits/libc-header-start.h>, which does not have a multiple include
+//    guard.  Feature test macros that can be handled from the first
+//    system header included are handled here.

+//    #endif
+//    Note: only works for GCC 2.0 and later, because __GNUC_MINOR__ was
+//    added in 2.0.
+
+// Similarly for clang.  Features added to GCC after version 4.2 may
+//    or may not also be available in clang, and clang's definitions of
+//    __GNUC(_MINOR)__ are fixed at 4 and 2 respectively.  Not all such

+
+// If _GNU_SOURCE was defined by the user, turn on all the other features.
+
+// If nothing (other than _GNU_SOURCE and _DEFAULT_SOURCE) is defined,

+
+// Some C libraries once required _REENTRANT and/or _THREAD_SAFE to be

+
+// We are almost always included from features.h.
+
+// The GNU libc does not support any K&R compilers or the traditional mode
+//    of ISO C compilers anymore.  Check for some of the combinations not
+//    supported anymore.
+
+// Some user header file might have defined this before.
+
+// Compilers that lack __has_attribute may object to
+//        #if defined __has_attribute && __has_attribute (...)
+//    even though they do not need to evaluate the right-hand side of the &&.
+//    Similarly for __has_builtin, etc.
+
+// All functions, except those with callbacks or those that
+//    synchronize memory, are leaf functions.
+
+// GCC can always grok prototypes.  For C++ programs we add throw()
+//    to help it optimize the function calls.  But this only works with
+//    gcc 2.8.x and egcs.  For gcc 3.4 and up we even mark C functions
+//    as non-throwing using a function attribute since programs can use
+//    the -fexceptions options for C code as well.
+
+// These two macros are not used in glibc anymore.  They are kept here
+//    only because some other projects expect the macros to be defined.
+
+// For these things, GCC behaves the ANSI way normally,
+//    and the non-ANSI way under -traditional.
+
+// This is not a typedef so `const __ptr_t' does the right thing.
+
+// C++ needs to know that types and declarations are C, not C++.
+
+// Fortify support.
+
+// Use __builtin_dynamic_object_size at _FORTIFY_SOURCE=3 when available.
+
+// Support for flexible arrays.
+//    Headers that should use flexible arrays only if they're "real"
+//    (e.g. only if they won't affect sizeof()) should test
+//    #if __glibc_c99_flexarr_available.
+
+// __asm__ ("xyz") is used throughout the headers to rename functions
+//    at the assembly language level.  This is wrapped by the __REDIRECT
+//    macro, in order to support compilers that can do this some other
+//    way.  When compilers don't support asm-names at all, we have to do
+//    preprocessor tricks instead (which don't have exactly the right
+//    semantics, but it's the best we can do).
+//
+//    Example:
+//    int __REDIRECT(setpgrp, (__pid_t pid, __pid_t pgrp), setpgid);
+
+//
+// #elif __SOME_OTHER_COMPILER__
+//
+// # define __REDIRECT(name, proto, alias) name proto; 	_Pragma("let " #name " = " #alias)
+
+// GCC and clang have various useful declarations that can be made with
+//    the '__attribute__' syntax.  All of the ways we use this do fine if
+//    they are omitted for compilers that don't understand it.
+
+// At some point during the gcc 2.96 development the `malloc' attribute
+//    for functions was introduced.  We don't want to use it unconditionally
+//    (although this would be possible) since it generates warnings.
+
+// Tell the compiler which arguments to an allocation function
+//    indicate the size of the allocation.
+
+// Tell the compiler which argument to an allocation function
+//    indicates the alignment of the allocation.
+
+// At some point during the gcc 2.96 development the `pure' attribute
+//    for functions was introduced.  We don't want to use it unconditionally
+//    (although this would be possible) since it generates warnings.
+
+// This declaration tells the compiler that the value is constant.
+
+// At some point during the gcc 3.1 development the `used' attribute
+//    for functions was introduced.  We don't want to use it unconditionally
+//    (although this would be possible) since it generates warnings.
+
+// Since version 3.2, gcc allows marking deprecated functions.
+
+// Since version 4.5, gcc also allows one to specify the message printed
+//    when a deprecated function is used.  clang claims to be gcc 4.2, but
+//    may also support this feature.
+
+// At some point during the gcc 2.8 development the `format_arg' attribute
+//    for functions was introduced.  We don't want to use it unconditionally
+//    (although this would be possible) since it generates warnings.
+//    If several `format_arg' attributes are given for the same function, in
+//    gcc-3.0 and older, all but the last one are ignored.  In newer gccs,
+//    all designated arguments are considered.
+
+// At some point during the gcc 2.97 development the `strfmon' format
+//    attribute for functions was introduced.  We don't want to use it
+//    unconditionally (although this would be possible) since it
+//    generates warnings.
+
+// The nonnull function attribute marks pointer parameters that
+//    must not be NULL.  This has the name __nonnull in glibc,
+//    and __attribute_nonnull__ in files shared with Gnulib to avoid
+//    collision with a different __nonnull in DragonFlyBSD 5.9.
+
+// The returns_nonnull function attribute marks the return type of the function
+//    as always being non-null.
+
+// If fortification mode, we warn about unused results of certain
+//    function calls which can lead to problems.
+
+// Forces a function to be always inlined.
+// The Linux kernel defines __always_inline in stddef.h (283d7573), and
+//    it conflicts with this definition.  Therefore undefine it first to
+//    allow either header to be included first.
+
+// Associate error messages with the source location of the call site rather
+//    than with the source location inside the function.
+
+// GCC 4.3 and above with -std=c99 or -std=gnu99 implements ISO C99
+//    inline semantics, unless -fgnu89-inline is used.  Using __GNUC_STDC_INLINE__
+//    or __GNUC_GNU_INLINE is not a good enough check for gcc because gcc versions
+//    older than 4.3 may define these macros and still not guarantee GNU inlining
+//    semantics.
+//
+//    clang++ identifies itself as gcc-4.2, but has support for GNU inlining
+//    semantics, that can be checked for by using the __GNUC_STDC_INLINE_ and
+//    __GNUC_GNU_INLINE__ macro definitions.
+
+// GCC 4.3 and above allow passing all anonymous arguments of an
+//    __extern_always_inline function to some other vararg function.
+
+// It is possible to compile containing GCC extensions even if GCC is
+//    run in pedantic mode if the uses are carefully marked using the
+//    `__extension__' keyword.  But this is not generally available before
+//    version 2.8.
+
+// __restrict is known in EGCS 1.2 and above, and in clang.
+//    It works also in C++ mode (outside of arrays), but only when spelled
+//    as '__restrict', not 'restrict'.
+
+// ISO C99 also allows to declare arrays as non-overlapping.  The syntax is
+//      array_name[restrict]
+//    GCC 3.1 and clang support this.
+//    This syntax is not usable in C++ mode.
+
+// Describes a char array whose address can safely be passed as the first
+//    argument to strncpy and strncat, as the char array is not necessarily
+//    a NUL-terminated string.
+
+// Undefine (also defined in libc-symbols.h).
+// Copies attributes from the declaration or type referenced by
+//    the argument.
+
+// Gnulib avoids including these, as they don't work on non-glibc or
+//    older glibc platforms.

+//
+//    These are defined by this file and are used by the

+//
+//    __GLIBC_USE (F)	Define things from feature set F.  This is defined
+// 			to 1 or 0; the subsequent macros are either defined
+// 			or undefined, and those tests should be moved to

+//    __USE_ISOC11		Define ISO C11 things.
+//    __USE_ISOC99		Define ISO C99 things.
+//    __USE_ISOC95		Define ISO C90 AMD1 (C95) things.
+//    __USE_ISOCXX11	Define ISO C++11 things.
+//    __USE_POSIX		Define IEEE Std 1003.1 things.
+//    __USE_POSIX2		Define IEEE Std 1003.2 things.
+//    __USE_POSIX199309	Define IEEE Std 1003.1, and .1b things.
+//    __USE_POSIX199506	Define IEEE Std 1003.1, .1b, .1c and .1i things.

+//    __USE_FILE_OFFSET64	Define 64bit interface as default.
+//    __USE_MISC		Define things from 4.3BSD or System V Unix.
+//    __USE_ATFILE		Define *at interfaces and AT_* constants for them.
+//    __USE_GNU		Define GNU extensions.
+//    __USE_FORTIFY_LEVEL	Additional security measures used, according to level.
+//
+//    The macros `__GNU_LIBRARY__', `__GLIBC__', and `__GLIBC_MINOR__' are
+//    defined by this file unconditionally.  `__GNU_LIBRARY__' is provided
+//    only for compatibility.  All new code should use the other symbols
+//    to test for features.
+//
+//    All macros listed above as possibly being defined by this file are
+//    explicitly undefined if they are not explicitly defined.
+//    Feature-test macros that are not defined by the user or compiler
+//    but are implied by the other feature-test macros defined (or by the
+//    lack of any definitions) are defined by the file.
+//
+//    ISO C feature test macros depend on the definition of the macro
+//    when an affected header is included, not when the first system
+//    header is included, and so they are handled in
+//    <bits/libc-header-start.h>, which does not have a multiple include
+//    guard.  Feature test macros that can be handled from the first
+//    system header included are handled here.
+
+// Undefine everything, so we get a clean slate.
+
+// Suppress kernel-name space pollution unless user expressedly asks
+//    for it.
+
+// Convenience macro to test the version of gcc.
+//    Use like this:
+//    #if __GNUC_PREREQ (2,8)
+//    ... code requiring gcc 2.8 or later ...
+//    #endif
+//    Note: only works for GCC 2.0 and later, because __GNUC_MINOR__ was
+//    added in 2.0.
+
+// Similarly for clang.  Features added to GCC after version 4.2 may
+//    or may not also be available in clang, and clang's definitions of
+//    __GNUC(_MINOR)__ are fixed at 4 and 2 respectively.  Not all such
+//    features can be queried via __has_extension/__has_feature.
+
+// Whether to use feature set F.
+
+// _BSD_SOURCE and _SVID_SOURCE are deprecated aliases for
+//    _DEFAULT_SOURCE.  If _DEFAULT_SOURCE is present we do not
+//    issue a warning; the expectation is that the source is being
+//    transitioned to use the new macro.
+
+// If _GNU_SOURCE was defined by the user, turn on all the other features.
+
+// If nothing (other than _GNU_SOURCE and _DEFAULT_SOURCE) is defined,
+//    define _DEFAULT_SOURCE.
+
+// This is to enable the ISO C2X extension.
+
+// This is to enable the ISO C11 extension.
+
+// This is to enable the ISO C99 extension.
+
+// This is to enable the ISO C90 Amendment 1:1995 extension.
+
+// If none of the ANSI/POSIX macros are defined, or if _DEFAULT_SOURCE
+//    is defined, use POSIX.1-2008 (or another version depending on
+//    _XOPEN_SOURCE).
+
+// Some C libraries once required _REENTRANT and/or _THREAD_SAFE to be
+//    defined in all multithreaded code.  GNU libc has not required this
+//    for many years.  We now treat them as compatibility synonyms for
+//    _POSIX_C_SOURCE=199506L, which is the earliest level of POSIX with
+//    comprehensive support for multithreaded code.  Using them never
+//    lowers the selected level of POSIX conformance, only raises it.
+
+// The function 'gets' existed in C89, but is impossible to use
+//    safely.  It has been removed from ISO C11 and ISO C++14.  Note: for
+//    compatibility with various implementations of <cstdio>, this test
+//    must consider only the value of __cplusplus when compiling C++.
+
+// GNU formerly extended the scanf functions with modified format
+//    specifiers %as, %aS, and %a[...] that allocate a buffer for the
+//    input using malloc.  This extension conflicts with ISO C99, which
+//    defines %a as a standalone format specifier that reads a floating-
+//    point number; moreover, POSIX.1-2008 provides the same feature
+//    using the modifier letter 'm' instead (%ms, %mS, %m[...]).
+//
+//    We now follow C99 unless GNU extensions are active and the compiler
+//    is specifically in C89 or C++98 mode (strict or not).  For
+//    instance, with GCC, -std=gnu11 will have C99-compliant scanf with
+//    or without -D_GNU_SOURCE, but -std=c89 -D_GNU_SOURCE will have the
+//    old extension.

+// We are almost always included from features.h.
+
+// The GNU libc does not support any K&R compilers or the traditional mode
+//    of ISO C compilers anymore.  Check for some of the combinations not
+//    anymore supported.
+
+// Some user header file might have defined this before.
+
+// All functions, except those with callbacks or those that
+//    synchronize memory, are leaf functions.
+
+// GCC can always grok prototypes.  For C++ programs we add throw()
+//    to help it optimize the function calls.  But this works only with
+//    gcc 2.8.x and egcs.  For gcc 3.2 and up we even mark C functions
+//    as non-throwing using a function attribute since programs can use
+//    the -fexceptions options for C code as well.
+
+// Compilers that are not clang may object to
+//        #if defined __clang__ && __has_extension(...)
+//    even though they do not need to evaluate the right-hand side of the &&.
+
+// These two macros are not used in glibc anymore.  They are kept here
+//    only because some other projects expect the macros to be defined.
+
+// For these things, GCC behaves the ANSI way normally,
+//    and the non-ANSI way under -traditional.
+
+// This is not a typedef so `const __ptr_t' does the right thing.
+
+// C++ needs to know that types and declarations are C, not C++.
+
+// Fortify support.
+
+// Support for flexible arrays.
+//    Headers that should use flexible arrays only if they're "real"
+//    (e.g. only if they won't affect sizeof()) should test
+//    #if __glibc_c99_flexarr_available.
+
+// __asm__ ("xyz") is used throughout the headers to rename functions
+//    at the assembly language level.  This is wrapped by the __REDIRECT
+//    macro, in order to support compilers that can do this some other
+//    way.  When compilers don't support asm-names at all, we have to do
+//    preprocessor tricks instead (which don't have exactly the right
+//    semantics, but it's the best we can do).
+//
+//    Example:
+//    int __REDIRECT(setpgrp, (__pid_t pid, __pid_t pgrp), setpgid);
+
+//
+// #elif __SOME_OTHER_COMPILER__
+//
+// # define __REDIRECT(name, proto, alias) name proto; 	_Pragma("let " #name " = " #alias)
+
+// GCC has various useful declarations that can be made with the
+//    `__attribute__' syntax.  All of the ways we use this do fine if
+//    they are omitted for compilers that don't understand it.
+
+// At some point during the gcc 2.96 development the `malloc' attribute
+//    for functions was introduced.  We don't want to use it unconditionally
+//    (although this would be possible) since it generates warnings.
+
+// Tell the compiler which arguments to an allocation function
+//    indicate the size of the allocation.
+
+// At some point during the gcc 2.96 development the `pure' attribute
+//    for functions was introduced.  We don't want to use it unconditionally
+//    (although this would be possible) since it generates warnings.
+
+// This declaration tells the compiler that the value is constant.
+
+// At some point during the gcc 3.1 development the `used' attribute
+//    for functions was introduced.  We don't want to use it unconditionally
+//    (although this would be possible) since it generates warnings.
+
+// Since version 3.2, gcc allows marking deprecated functions.
+
+// Since version 4.5, gcc also allows one to specify the message printed
+//    when a deprecated function is used.  clang claims to be gcc 4.2, but
+//    may also support this feature.
+
+// At some point during the gcc 2.8 development the `format_arg' attribute
+//    for functions was introduced.  We don't want to use it unconditionally
+//    (although this would be possible) since it generates warnings.
+//    If several `format_arg' attributes are given for the same function, in
+//    gcc-3.0 and older, all but the last one are ignored.  In newer gccs,
+//    all designated arguments are considered.
+
+// At some point during the gcc 2.97 development the `strfmon' format
+//    attribute for functions was introduced.  We don't want to use it
+//    unconditionally (although this would be possible) since it
+//    generates warnings.
+
+// The nonull function attribute allows to mark pointer parameters which
+//    must not be NULL.
+
+// If fortification mode, we warn about unused results of certain
+//    function calls which can lead to problems.
+
+// Forces a function to be always inlined.
+// The Linux kernel defines __always_inline in stddef.h (283d7573), and
+//    it conflicts with this definition.  Therefore undefine it first to
+//    allow either header to be included first.
+
+// Associate error messages with the source location of the call site rather
+//    than with the source location inside the function.
+
+// GCC 4.3 and above with -std=c99 or -std=gnu99 implements ISO C99
+//    inline semantics, unless -fgnu89-inline is used.  Using __GNUC_STDC_INLINE__
+//    or __GNUC_GNU_INLINE is not a good enough check for gcc because gcc versions
+//    older than 4.3 may define these macros and still not guarantee GNU inlining
+//    semantics.
+//
+//    clang++ identifies itself as gcc-4.2, but has support for GNU inlining
+//    semantics, that can be checked for by using the __GNUC_STDC_INLINE_ and
+//    __GNUC_GNU_INLINE__ macro definitions.
+
+// GCC 4.3 and above allow passing all anonymous arguments of an
+//    __extern_always_inline function to some other vararg function.
+
+// It is possible to compile containing GCC extensions even if GCC is
+//    run in pedantic mode if the uses are carefully marked using the
+//    `__extension__' keyword.  But this is not generally available before
+//    version 2.8.
+
+// __restrict is known in EGCS 1.2 and above.
+
+// ISO C99 also allows to declare arrays as non-overlapping.  The syntax is
+//      array_name[restrict]
+//    GCC 3.1 supports this.

+//
+//    These are defined by this file and are used by the

+//
+//    __GLIBC_USE (F)	Define things from feature set F.  This is defined

+//    __USE_POSIX199309	Define IEEE Std 1003.1, and .1b things.

+//    __USE_FILE_OFFSET64	Define 64bit interface as default.
+//    __USE_MISC		Define things from 4.3BSD or System V Unix.
+//    __USE_ATFILE		Define *at interfaces and AT_* constants for them.
+//    __USE_GNU		Define GNU extensions.
+//    __USE_FORTIFY_LEVEL	Additional security measures used, according to level.
+//
+//    The macros `__GNU_LIBRARY__', `__GLIBC__', and `__GLIBC_MINOR__' are
+//    defined by this file unconditionally.  `__GNU_LIBRARY__' is provided
+//    only for compatibility.  All new code should use the other symbols
+//    to test for features.
+//
+//    All macros listed above as possibly being defined by this file are
+//    explicitly undefined if they are not explicitly defined.
+//    Feature-test macros that are not defined by the user or compiler
+//    but are implied by the other feature-test macros defined (or by the
+//    lack of any definitions) are defined by the file.
+//
+//    ISO C feature test macros depend on the definition of the macro
+//    when an affected header is included, not when the first system
+//    header is included, and so they are handled in
+//    <bits/libc-header-start.h>, which does not have a multiple include
+//    guard.  Feature test macros that can be handled from the first
+//    system header included are handled here.
+
+// Undefine everything, so we get a clean slate.
+
+// Suppress kernel-name space pollution unless user expressedly asks
+//    for it.
+
+// Convenience macro to test the version of gcc.
+//    Use like this:
+//    #if __GNUC_PREREQ (2,8)
+//    ... code requiring gcc 2.8 or later ...
+//    #endif
+//    Note: only works for GCC 2.0 and later, because __GNUC_MINOR__ was
+//    added in 2.0.
+
+// Similarly for clang.  Features added to GCC after version 4.2 may
+//    or may not also be available in clang, and clang's definitions of
+//    __GNUC(_MINOR)__ are fixed at 4 and 2 respectively.  Not all such
+//    features can be queried via __has_extension/__has_feature.
+
+// Whether to use feature set F.
+
+// _BSD_SOURCE and _SVID_SOURCE are deprecated aliases for
+//    _DEFAULT_SOURCE.  If _DEFAULT_SOURCE is present we do not
+//    issue a warning; the expectation is that the source is being
+//    transitioned to use the new macro.
+
+// If _GNU_SOURCE was defined by the user, turn on all the other features.
+
+// If nothing (other than _GNU_SOURCE and _DEFAULT_SOURCE) is defined,
+//    define _DEFAULT_SOURCE.
+
+// This is to enable the ISO C2X extension.
+
+// This is to enable the ISO C11 extension.
+
+// This is to enable the ISO C99 extension.
+
+// This is to enable the ISO C90 Amendment 1:1995 extension.
+
+// If none of the ANSI/POSIX macros are defined, or if _DEFAULT_SOURCE
+//    is defined, use POSIX.1-2008 (or another version depending on
+//    _XOPEN_SOURCE).
+
+// Some C libraries once required _REENTRANT and/or _THREAD_SAFE to be
+//    defined in all multithreaded code.  GNU libc has not required this
+//    for many years.  We now treat them as compatibility synonyms for
+//    _POSIX_C_SOURCE=199506L, which is the earliest level of POSIX with
+//    comprehensive support for multithreaded code.  Using them never
+//    lowers the selected level of POSIX conformance, only raises it.
+
+// The function 'gets' existed in C89, but is impossible to use
+//    safely.  It has been removed from ISO C11 and ISO C++14.  Note: for
+//    compatibility with various implementations of <cstdio>, this test
+//    must consider only the value of __cplusplus when compiling C++.
+
+// GNU formerly extended the scanf functions with modified format
+//    specifiers %as, %aS, and %a[...] that allocate a buffer for the
+//    input using malloc.  This extension conflicts with ISO C99, which
+//    defines %a as a standalone format specifier that reads a floating-
+//    point number; moreover, POSIX.1-2008 provides the same feature
+//    using the modifier letter 'm' instead (%ms, %mS, %m[...]).
+//
+//    We now follow C99 unless GNU extensions are active and the compiler
+//    is specifically in C89 or C++98 mode (strict or not).  For
+//    instance, with GCC, -std=gnu11 will have C99-compliant scanf with
+//    or without -D_GNU_SOURCE, but -std=c89 -D_GNU_SOURCE will have the
+//    old extension.

+// The GNU libc does not support any K&R compilers or the traditional mode
+//    of ISO C compilers anymore.  Check for some of the combinations not
+//    anymore supported.
+
+// Some user header file might have defined this before.
+
+// All functions, except those with callbacks or those that
+//    synchronize memory, are leaf functions.
+
+// GCC can always grok prototypes.  For C++ programs we add throw()
+//    to help it optimize the function calls.  But this works only with
+//    gcc 2.8.x and egcs.  For gcc 3.2 and up we even mark C functions
+//    as non-throwing using a function attribute since programs can use
+//    the -fexceptions options for C code as well.
+
+// Compilers that are not clang may object to
+//        #if defined __clang__ && __has_extension(...)
+//    even though they do not need to evaluate the right-hand side of the &&.
+
+// These two macros are not used in glibc anymore.  They are kept here
+//    only because some other projects expect the macros to be defined.
+
+// For these things, GCC behaves the ANSI way normally,
+//    and the non-ANSI way under -traditional.
+
+// This is not a typedef so `const __ptr_t' does the right thing.
+
+// C++ needs to know that types and declarations are C, not C++.
+
+// Fortify support.
+
+// Support for flexible arrays.
+//    Headers that should use flexible arrays only if they're "real"
+//    (e.g. only if they won't affect sizeof()) should test
+//    #if __glibc_c99_flexarr_available.
+
+// __asm__ ("xyz") is used throughout the headers to rename functions
+//    at the assembly language level.  This is wrapped by the __REDIRECT
+//    macro, in order to support compilers that can do this some other
+//    way.  When compilers don't support asm-names at all, we have to do
+//    preprocessor tricks instead (which don't have exactly the right
+//    semantics, but it's the best we can do).
+//
+//    Example:
+//    int __REDIRECT(setpgrp, (__pid_t pid, __pid_t pgrp), setpgid);
+
+//
+// #elif __SOME_OTHER_COMPILER__
+//
+// # define __REDIRECT(name, proto, alias) name proto; 	_Pragma("let " #name " = " #alias)
+
+// GCC has various useful declarations that can be made with the
+//    `__attribute__' syntax.  All of the ways we use this do fine if
+//    they are omitted for compilers that don't understand it.
+
+// At some point during the gcc 2.96 development the `malloc' attribute
+//    for functions was introduced.  We don't want to use it unconditionally
+//    (although this would be possible) since it generates warnings.
+
+// Tell the compiler which arguments to an allocation function
+//    indicate the size of the allocation.
+
+// At some point during the gcc 2.96 development the `pure' attribute
+//    for functions was introduced.  We don't want to use it unconditionally
+//    (although this would be possible) since it generates warnings.
+
+// This declaration tells the compiler that the value is constant.
+
+// At some point during the gcc 3.1 development the `used' attribute
+//    for functions was introduced.  We don't want to use it unconditionally
+//    (although this would be possible) since it generates warnings.
+
+// Since version 3.2, gcc allows marking deprecated functions.
+
+// Since version 4.5, gcc also allows one to specify the message printed
+//    when a deprecated function is used.  clang claims to be gcc 4.2, but
+//    may also support this feature.
+
+// At some point during the gcc 2.8 development the `format_arg' attribute
+//    for functions was introduced.  We don't want to use it unconditionally
+//    (although this would be possible) since it generates warnings.
+//    If several `format_arg' attributes are given for the same function, in
+//    gcc-3.0 and older, all but the last one are ignored.  In newer gccs,
+//    all designated arguments are considered.
+
+// At some point during the gcc 2.97 development the `strfmon' format
+//    attribute for functions was introduced.  We don't want to use it
+//    unconditionally (although this would be possible) since it
+//    generates warnings.
+
+// The nonull function attribute allows to mark pointer parameters which
+//    must not be NULL.
+
+// If fortification mode, we warn about unused results of certain
+//    function calls which can lead to problems.
+
+// Forces a function to be always inlined.
+// The Linux kernel defines __always_inline in stddef.h (283d7573), and
+//    it conflicts with this definition.  Therefore undefine it first to
+//    allow either header to be included first.
+
+// Associate error messages with the source location of the call site rather
+//    than with the source location inside the function.
+
+// GCC 4.3 and above with -std=c99 or -std=gnu99 implements ISO C99
+//    inline semantics, unless -fgnu89-inline is used.  Using __GNUC_STDC_INLINE__
+//    or __GNUC_GNU_INLINE is not a good enough check for gcc because gcc versions
+//    older than 4.3 may define these macros and still not guarantee GNU inlining
+//    semantics.
+//
+//    clang++ identifies itself as gcc-4.2, but has support for GNU inlining
+//    semantics, that can be checked for by using the __GNUC_STDC_INLINE_ and
+//    __GNUC_GNU_INLINE__ macro definitions.
+
+// GCC 4.3 and above allow passing all anonymous arguments of an
+//    __extern_always_inline function to some other vararg function.
+
+// It is possible to compile containing GCC extensions even if GCC is
+//    run in pedantic mode if the uses are carefully marked using the
+//    `__extension__' keyword.  But this is not generally available before
+//    version 2.8.
+
+// __restrict is known in EGCS 1.2 and above.
+
+// ISO C99 also allows to declare arrays as non-overlapping.  The syntax is
+//      array_name[restrict]
+//    GCC 3.1 supports this.
+
+// Describes a char array whose address can safely be passed as the first

+// __glibc_macro_warning (MESSAGE) issues warning MESSAGE.  This is

+// Generic selection (ISO C11) is a C-only feature, available in GCC
+//    since version 4.9.  Previous versions do not provide generic
+//    selection, even though they might set __STDC_VERSION__ to 201112L,
+//    when in -std=c11 mode.  Thus, we must check for !defined __GNUC__
+//    when testing __STDC_VERSION__ for generic selection support.
+//    On the other hand, Clang also defines __GNUC__, so a clang-specific
+//    check is required to enable the use of generic selection.
+
+// If we don't have __REDIRECT, prototypes will be missing if
+//    __USE_FILE_OFFSET64 but not __USE_LARGEFILE[64].

+//    We define __S<SIZE>_TYPE and __U<SIZE>_TYPE for the signed and unsigned
+//    variants of each of the following integer types on this machine.
+//
+// 	16		-- "natural" 16-bit type (always short)
+// 	32		-- "natural" 32-bit type (always int)
+// 	64		-- "natural" 64-bit type (long or long long)
+// 	LONG32		-- 32-bit type, traditionally long
+// 	QUAD		-- 64-bit type, traditionally long long
+// 	WORD		-- natural type of __WORDSIZE bits (int or long)
+// 	LONGWORD	-- type of __WORDSIZE bits, traditionally long
+//
+//    We distinguish WORD/LONGWORD, 32/LONG32, and 64/QUAD so that the
+//    conventional uses of `long' or `long long' type modifiers match the
+//    types we define, even when a less-adorned type would be the same size.
+//    This matters for (somewhat) portably writing printf/scanf formats for
+//    these types, where using the appropriate l or ll format modifiers can
+//    make the typedefs and the formats match up across all GNU platforms.  If
+//    we used `long' when it's 64 bits where `long long' is expected, then the
+//    compiler would warn about the formats not matching the argument types,
+//    and the programmer changing them to shut up the compiler would break the
+//    program's portability.
+//
+//    Here we assume what is presently the case in all the GCC configurations
+//    we support: long long is always 64 bits, long is always word/address size,
+//    and int is always 32 bits.

+//    __USE_FILE_OFFSET64	Define 64bit interface as default.
+//    __USE_MISC		Define things from 4.3BSD or System V Unix.

+//    __USE_DYNAMIC_STACK_SIZE Define correct (but non compile-time constant)
+// 			MINSIGSTKSZ, SIGSTKSZ and PTHREAD_STACK_MIN.
+//    __USE_GNU		Define GNU extensions.
+//    __USE_FORTIFY_LEVEL	Additional security measures used, according to level.
+//
+//    The macros `__GNU_LIBRARY__', `__GLIBC__', and `__GLIBC_MINOR__' are
+//    defined by this file unconditionally.  `__GNU_LIBRARY__' is provided
+//    only for compatibility.  All new code should use the other symbols
+//    to test for features.
+//
+//    All macros listed above as possibly being defined by this file are
+//    explicitly undefined if they are not explicitly defined.
+//    Feature-test macros that are not defined by the user or compiler
+//    but are implied by the other feature-test macros defined (or by the
+//    lack of any definitions) are defined by the file.
+//
+//    ISO C feature test macros depend on the definition of the macro
+//    when an affected header is included, not when the first system
+//    header is included, and so they are handled in
+//    <bits/libc-header-start.h>, which does not have a multiple include
+//    guard.  Feature test macros that can be handled from the first
+//    system header included are handled here.
+

+//    #if __GNUC_PREREQ (2,8)
+//    ... code requiring gcc 2.8 or later ...
+//    #endif
+//    Note: only works for GCC 2.0 and later, because __GNUC_MINOR__ was
+//    added in 2.0.
+
+// Similarly for clang.  Features added to GCC after version 4.2 may
+//    or may not also be available in clang, and clang's definitions of
+//    __GNUC(_MINOR)__ are fixed at 4 and 2 respectively.  Not all such
+//    features can be queried via __has_extension/__has_feature.
+
+// Whether to use feature set F.
+
+// _BSD_SOURCE and _SVID_SOURCE are deprecated aliases for
+//    _DEFAULT_SOURCE.  If _DEFAULT_SOURCE is present we do not
+//    issue a warning; the expectation is that the source is being
+//    transitioned to use the new macro.
+
+// If _GNU_SOURCE was defined by the user, turn on all the other features.
+
+// If nothing (other than _GNU_SOURCE and _DEFAULT_SOURCE) is defined,
+//    define _DEFAULT_SOURCE.
+
+// This is to enable the ISO C2X extension.
+
+// This is to enable the ISO C11 extension.
+
+// This is to enable the ISO C99 extension.
+
+// This is to enable the ISO C90 Amendment 1:1995 extension.
+
+// If none of the ANSI/POSIX macros are defined, or if _DEFAULT_SOURCE
+//    is defined, use POSIX.1-2008 (or another version depending on
+//    _XOPEN_SOURCE).
+
+// Some C libraries once required _REENTRANT and/or _THREAD_SAFE to be
+//    defined in all multithreaded code.  GNU libc has not required this
+//    for many years.  We now treat them as compatibility synonyms for
+//    _POSIX_C_SOURCE=199506L, which is the earliest level of POSIX with

+//
+//    We now follow C99 unless GNU extensions are active and the compiler

+// We are almost always included from features.h.
+
+// The GNU libc does not support any K&R compilers or the traditional mode
+//    of ISO C compilers anymore.  Check for some of the combinations not
+//    supported anymore.
+
+// Some user header file might have defined this before.
+
+// Compilers that lack __has_attribute may object to
+//        #if defined __has_attribute && __has_attribute (...)
+//    even though they do not need to evaluate the right-hand side of the &&.
+//    Similarly for __has_builtin, etc.
+
+// All functions, except those with callbacks or those that
+//    synchronize memory, are leaf functions.
+
+// GCC can always grok prototypes.  For C++ programs we add throw()
+//    to help it optimize the function calls.  But this only works with
+//    gcc 2.8.x and egcs.  For gcc 3.4 and up we even mark C functions
+//    as non-throwing using a function attribute since programs can use
+//    the -fexceptions options for C code as well.
+
+// These two macros are not used in glibc anymore.  They are kept here
+//    only because some other projects expect the macros to be defined.
+
+// For these things, GCC behaves the ANSI way normally,
+//    and the non-ANSI way under -traditional.
+
+// This is not a typedef so `const __ptr_t' does the right thing.
+
+// C++ needs to know that types and declarations are C, not C++.
+
+// Fortify support.
+
+// Use __builtin_dynamic_object_size at _FORTIFY_SOURCE=3 when available.
+
+// Support for flexible arrays.
+//    Headers that should use flexible arrays only if they're "real"
+//    (e.g. only if they won't affect sizeof()) should test
+//    #if __glibc_c99_flexarr_available.
+
+// __asm__ ("xyz") is used throughout the headers to rename functions
+//    at the assembly language level.  This is wrapped by the __REDIRECT
+//    macro, in order to support compilers that can do this some other
+//    way.  When compilers don't support asm-names at all, we have to do
+//    preprocessor tricks instead (which don't have exactly the right
+//    semantics, but it's the best we can do).
+//
+//    Example:
+//    int __REDIRECT(setpgrp, (__pid_t pid, __pid_t pgrp), setpgid);
+
+//
+// #elif __SOME_OTHER_COMPILER__
+//
+// # define __REDIRECT(name, proto, alias) name proto; 	_Pragma("let " #name " = " #alias)
+
+// GCC and clang have various useful declarations that can be made with
+//    the '__attribute__' syntax.  All of the ways we use this do fine if
+//    they are omitted for compilers that don't understand it.
+
+// At some point during the gcc 2.96 development the `malloc' attribute
+//    for functions was introduced.  We don't want to use it unconditionally
+//    (although this would be possible) since it generates warnings.
+
+// Tell the compiler which arguments to an allocation function
+//    indicate the size of the allocation.
+
+// At some point during the gcc 2.96 development the `pure' attribute
+//    for functions was introduced.  We don't want to use it unconditionally
+//    (although this would be possible) since it generates warnings.
+
+// This declaration tells the compiler that the value is constant.
+
+// At some point during the gcc 3.1 development the `used' attribute
+//    for functions was introduced.  We don't want to use it unconditionally
+//    (although this would be possible) since it generates warnings.
+
+// Since version 3.2, gcc allows marking deprecated functions.
+
+// Since version 4.5, gcc also allows one to specify the message printed
+//    when a deprecated function is used.  clang claims to be gcc 4.2, but
+//    may also support this feature.
+
+// At some point during the gcc 2.8 development the `format_arg' attribute
+//    for functions was introduced.  We don't want to use it unconditionally
+//    (although this would be possible) since it generates warnings.
+//    If several `format_arg' attributes are given for the same function, in
+//    gcc-3.0 and older, all but the last one are ignored.  In newer gccs,
+//    all designated arguments are considered.
+
+// At some point during the gcc 2.97 development the `strfmon' format
+//    attribute for functions was introduced.  We don't want to use it
+//    unconditionally (although this would be possible) since it
+//    generates warnings.
+
+// The nonnull function attribute marks pointer parameters that
+//    must not be NULL.
+
+// The returns_nonnull function attribute marks the return type of the function
+//    as always being non-null.
+
+// If fortification mode, we warn about unused results of certain
+//    function calls which can lead to problems.
+
+// Forces a function to be always inlined.
+// The Linux kernel defines __always_inline in stddef.h (283d7573), and
+//    it conflicts with this definition.  Therefore undefine it first to
+//    allow either header to be included first.
+
+// Associate error messages with the source location of the call site rather
+//    than with the source location inside the function.
+
+// GCC 4.3 and above with -std=c99 or -std=gnu99 implements ISO C99
+//    inline semantics, unless -fgnu89-inline is used.  Using __GNUC_STDC_INLINE__
+//    or __GNUC_GNU_INLINE is not a good enough check for gcc because gcc versions
+//    older than 4.3 may define these macros and still not guarantee GNU inlining
+//    semantics.
+//
+//    clang++ identifies itself as gcc-4.2, but has support for GNU inlining
+//    semantics, that can be checked for by using the __GNUC_STDC_INLINE_ and
+//    __GNUC_GNU_INLINE__ macro definitions.
+
+// GCC 4.3 and above allow passing all anonymous arguments of an
+//    __extern_always_inline function to some other vararg function.
+
+// It is possible to compile containing GCC extensions even if GCC is
+//    run in pedantic mode if the uses are carefully marked using the
+//    `__extension__' keyword.  But this is not generally available before
+//    version 2.8.
+
+// __restrict is known in EGCS 1.2 and above, and in clang.
+//    It works also in C++ mode (outside of arrays), but only when spelled
+//    as '__restrict', not 'restrict'.
+
+// ISO C99 also allows to declare arrays as non-overlapping.  The syntax is
+//      array_name[restrict]
+//    GCC 3.1 and clang support this.
+//    This syntax is not usable in C++ mode.
+
+// Describes a char array whose address can safely be passed as the first
+//    argument to strncpy and strncat, as the char array is not necessarily
+//    a NUL-terminated string.

+// The machine-dependent file <bits/typesizes.h> defines __*_T_TYPE
+//    macros for each of the OS types we define below.  The definitions
+//    of those macros must use the following macros for underlying types.
+//    We define __S<SIZE>_TYPE and __U<SIZE>_TYPE for the signed and unsigned
+//    variants of each of the following integer types on this machine.
+//
+// 	16		-- "natural" 16-bit type (always short)
+// 	32		-- "natural" 32-bit type (always int)
+// 	64		-- "natural" 64-bit type (long or long long)
+// 	LONG32		-- 32-bit type, traditionally long
+// 	QUAD		-- 64-bit type, traditionally long long
+// 	WORD		-- natural type of __WORDSIZE bits (int or long)
+// 	LONGWORD	-- type of __WORDSIZE bits, traditionally long
+//
+//    We distinguish WORD/LONGWORD, 32/LONG32, and 64/QUAD so that the
+//    conventional uses of `long' or `long long' type modifiers match the
+//    types we define, even when a less-adorned type would be the same size.
+//    This matters for (somewhat) portably writing printf/scanf formats for
+//    these types, where using the appropriate l or ll format modifiers can
+//    make the typedefs and the formats match up across all GNU platforms.  If
+//    we used `long' when it's 64 bits where `long long' is expected, then the
+//    compiler would warn about the formats not matching the argument types,
+//    and the programmer changing them to shut up the compiler would break the
+//    program's portability.
+//
+//    Here we assume what is presently the case in all the GCC configurations
+//    we support: long long is always 64 bits, long is always word/address size,
+//    and int is always 32 bits.
+
+// No need to mark the typedef with __extension__.

+//    The `-ansi' switch to the GNU C compiler, and standards conformance

+//    give you ISO C, 1003.1, and 1003.2, but nothing else.
+//
+//    These are defined by this file and are used by the
+//    header files to decide what to declare or define:
+//
+//    __GLIBC_USE (F)	Define things from feature set F.  This is defined
+// 			to 1 or 0; the subsequent macros are either defined
+// 			or undefined, and those tests should be moved to
+// 			__GLIBC_USE.
+//    __USE_ISOC11		Define ISO C11 things.
+//    __USE_ISOC99		Define ISO C99 things.
+//    __USE_ISOC95		Define ISO C90 AMD1 (C95) things.
+//    __USE_ISOCXX11	Define ISO C++11 things.
+//    __USE_POSIX		Define IEEE Std 1003.1 things.
+//    __USE_POSIX2		Define IEEE Std 1003.2 things.
+//    __USE_POSIX199309	Define IEEE Std 1003.1, and .1b things.
+//    __USE_POSIX199506	Define IEEE Std 1003.1, .1b, .1c and .1i things.
+//    __USE_XOPEN		Define XPG things.
+//    __USE_XOPEN_EXTENDED	Define X/Open Unix things.
+//    __USE_UNIX98		Define Single Unix V2 things.
+//    __USE_XOPEN2K        Define XPG6 things.

+//    __USE_XOPEN2K8       Define XPG7 things.
+//    __USE_XOPEN2K8XSI    Define XPG7 XSI things.
+//    __USE_LARGEFILE	Define correct standard I/O things.
+//    __USE_LARGEFILE64	Define LFS things with separate names.
+//    __USE_FILE_OFFSET64	Define 64bit interface as default.
+//    __USE_MISC		Define things from 4.3BSD or System V Unix.
+//    __USE_ATFILE		Define *at interfaces and AT_* constants for them.
+//    __USE_GNU		Define GNU extensions.
+//    __USE_FORTIFY_LEVEL	Additional security measures used, according to level.
+//
+//    The macros `__GNU_LIBRARY__', `__GLIBC__', and `__GLIBC_MINOR__' are
+//    defined by this file unconditionally.  `__GNU_LIBRARY__' is provided
+//    only for compatibility.  All new code should use the other symbols
+//    to test for features.
+//
+//    All macros listed above as possibly being defined by this file are
+//    explicitly undefined if they are not explicitly defined.
+//    Feature-test macros that are not defined by the user or compiler
+//    but are implied by the other feature-test macros defined (or by the
+//    lack of any definitions) are defined by the file.
+//
+//    ISO C feature test macros depend on the definition of the macro
+//    when an affected header is included, not when the first system
+//    header is included, and so they are handled in
+//    <bits/libc-header-start.h>, which does not have a multiple include
+//    guard.  Feature test macros that can be handled from the first
+//    system header included are handled here.
+
+// Undefine everything, so we get a clean slate.
+
+// Suppress kernel-name space pollution unless user expressedly asks
+//    for it.
+
+// Convenience macro to test the version of gcc.
+//    Use like this:
+//    #if __GNUC_PREREQ (2,8)
+//    ... code requiring gcc 2.8 or later ...
+//    #endif
+//    Note: only works for GCC 2.0 and later, because __GNUC_MINOR__ was
+//    added in 2.0.
+
+// Similarly for clang.  Features added to GCC after version 4.2 may
+//    or may not also be available in clang, and clang's definitions of
+//    __GNUC(_MINOR)__ are fixed at 4 and 2 respectively.  Not all such
+//    features can be queried via __has_extension/__has_feature.
+
+// Whether to use feature set F.
+
+// _BSD_SOURCE and _SVID_SOURCE are deprecated aliases for
+//    _DEFAULT_SOURCE.  If _DEFAULT_SOURCE is present we do not
+//    issue a warning; the expectation is that the source is being
+//    transitioned to use the new macro.
+
+// If _GNU_SOURCE was defined by the user, turn on all the other features.
+
+// If nothing (other than _GNU_SOURCE and _DEFAULT_SOURCE) is defined,
+//    define _DEFAULT_SOURCE.
+
+// This is to enable the ISO C2X extension.
+
+// This is to enable the ISO C11 extension.
+
+// This is to enable the ISO C99 extension.
+
+// This is to enable the ISO C90 Amendment 1:1995 extension.
+
+// If none of the ANSI/POSIX macros are defined, or if _DEFAULT_SOURCE
+//    is defined, use POSIX.1-2008 (or another version depending on
+//    _XOPEN_SOURCE).
+
+// Some C libraries once required _REENTRANT and/or _THREAD_SAFE to be
+//    defined in all multithreaded code.  GNU libc has not required this
+//    for many years.  We now treat them as compatibility synonyms for
+//    _POSIX_C_SOURCE=199506L, which is the earliest level of POSIX with
+//    comprehensive support for multithreaded code.  Using them never
+//    lowers the selected level of POSIX conformance, only raises it.
+
+// The function 'gets' existed in C89, but is impossible to use
+//    safely.  It has been removed from ISO C11 and ISO C++14.  Note: for
+//    compatibility with various implementations of <cstdio>, this test
+//    must consider only the value of __cplusplus when compiling C++.
+
+// GNU formerly extended the scanf functions with modified format
+//    specifiers %as, %aS, and %a[...] that allocate a buffer for the
+//    input using malloc.  This extension conflicts with ISO C99, which
+//    defines %a as a standalone format specifier that reads a floating-
+//    point number; moreover, POSIX.1-2008 provides the same feature
+//    using the modifier letter 'm' instead (%ms, %mS, %m[...]).
+//
+//    We now follow C99 unless GNU extensions are active and the compiler
+//    is specifically in C89 or C++98 mode (strict or not).  For
+//    instance, with GCC, -std=gnu11 will have C99-compliant scanf with
+//    or without -D_GNU_SOURCE, but -std=c89 -D_GNU_SOURCE will have the
+//    old extension.
+
+// Get definitions of __STDC_* predefined macros, if the compiler has
+//    not preincluded this header automatically.

+//    to help it optimize the function calls.  But this works only with
+//    gcc 2.8.x and egcs.  For gcc 3.2 and up we even mark C functions
+//    as non-throwing using a function attribute since programs can use
+//    the -fexceptions options for C code as well.
+
+// Compilers that are not clang may object to
+//        #if defined __clang__ && __has_extension(...)
+//    even though they do not need to evaluate the right-hand side of the &&.
+
+// These two macros are not used in glibc anymore.  They are kept here
+//    only because some other projects expect the macros to be defined.
+
+// For these things, GCC behaves the ANSI way normally,
+//    and the non-ANSI way under -traditional.
+
+// This is not a typedef so `const __ptr_t' does the right thing.
+
+// C++ needs to know that types and declarations are C, not C++.
+
+// Fortify support.
+
+// Support for flexible arrays.
+//    Headers that should use flexible arrays only if they're "real"
+//    (e.g. only if they won't affect sizeof()) should test
+//    #if __glibc_c99_flexarr_available.
+
+// __asm__ ("xyz") is used throughout the headers to rename functions
+//    at the assembly language level.  This is wrapped by the __REDIRECT
+//    macro, in order to support compilers that can do this some other
+//    way.  When compilers don't support asm-names at all, we have to do
+//    preprocessor tricks instead (which don't have exactly the right
+//    semantics, but it's the best we can do).
+//
+//    Example:
+//    int __REDIRECT(setpgrp, (__pid_t pid, __pid_t pgrp), setpgid);
+
+//
+// #elif __SOME_OTHER_COMPILER__
+//
+// # define __REDIRECT(name, proto, alias) name proto; 	_Pragma("let " #name " = " #alias)
+
+// GCC has various useful declarations that can be made with the
+//    `__attribute__' syntax.  All of the ways we use this do fine if
+//    they are omitted for compilers that don't understand it.
+
+// At some point during the gcc 2.96 development the `malloc' attribute
+//    for functions was introduced.  We don't want to use it unconditionally
+//    (although this would be possible) since it generates warnings.
+
+// Tell the compiler which arguments to an allocation function
+//    indicate the size of the allocation.
+
+// At some point during the gcc 2.96 development the `pure' attribute
+//    for functions was introduced.  We don't want to use it unconditionally
+//    (although this would be possible) since it generates warnings.
+
+// This declaration tells the compiler that the value is constant.
+
+// At some point during the gcc 3.1 development the `used' attribute
+//    for functions was introduced.  We don't want to use it unconditionally
+//    (although this would be possible) since it generates warnings.
+
+// Since version 3.2, gcc allows marking deprecated functions.
+
+// Since version 4.5, gcc also allows one to specify the message printed
+//    when a deprecated function is used.  clang claims to be gcc 4.2, but
+//    may also support this feature.
+
+// At some point during the gcc 2.8 development the `format_arg' attribute
+//    for functions was introduced.  We don't want to use it unconditionally
+//    (although this would be possible) since it generates warnings.
+//    If several `format_arg' attributes are given for the same function, in
+//    gcc-3.0 and older, all but the last one are ignored.  In newer gccs,
+//    all designated arguments are considered.
+
+// At some point during the gcc 2.97 development the `strfmon' format
+//    attribute for functions was introduced.  We don't want to use it
+//    unconditionally (although this would be possible) since it
+//    generates warnings.
+
+// The nonull function attribute allows to mark pointer parameters which
+//    must not be NULL.
+
+// If fortification mode, we warn about unused results of certain
+//    function calls which can lead to problems.
+
+// Forces a function to be always inlined.
+// The Linux kernel defines __always_inline in stddef.h (283d7573), and
+//    it conflicts with this definition.  Therefore undefine it first to
+//    allow either header to be included first.
+
+// Associate error messages with the source location of the call site rather
+//    than with the source location inside the function.
+
+// GCC 4.3 and above with -std=c99 or -std=gnu99 implements ISO C99
+//    inline semantics, unless -fgnu89-inline is used.  Using __GNUC_STDC_INLINE__
+//    or __GNUC_GNU_INLINE is not a good enough check for gcc because gcc versions
+//    older than 4.3 may define these macros and still not guarantee GNU inlining
+//    semantics.
+//
+//    clang++ identifies itself as gcc-4.2, but has support for GNU inlining
+//    semantics, that can be checked for by using the __GNUC_STDC_INLINE_ and
+//    __GNUC_GNU_INLINE__ macro definitions.
+
+// GCC 4.3 and above allow passing all anonymous arguments of an
+//    __extern_always_inline function to some other vararg function.
+
+// It is possible to compile containing GCC extensions even if GCC is
+//    run in pedantic mode if the uses are carefully marked using the
+//    `__extension__' keyword.  But this is not generally available before
+//    version 2.8.
+
+// __restrict is known in EGCS 1.2 and above.
+
+// ISO C99 also allows to declare arrays as non-overlapping.  The syntax is
+//      array_name[restrict]
+//    GCC 3.1 supports this.

+//
+// NOTE: Do not protect this header against multiple inclusion.  Doing
+// so can have subtle side-effects due to header file inclusion order
+// and testing of e.g. _POSIX_SOURCE vs. _POSIX_C_SOURCE.  Instead,
+// protect each CPP macro that we want to supply.
+
+// Feature-test macros are defined by several standards, and allow an
+// application to specify what symbols they want the system headers to
+// expose, and hence what standard they want them to conform to.
+// There are two classes of feature-test macros.  The first class
+// specify complete standards, and if one of these is defined, header
+// files will try to conform to the relevant standard.  They are:
+//
+// ANSI macros:
+// _ANSI_SOURCE			ANSI C89
+//
+// POSIX macros:
+// _POSIX_SOURCE == 1		IEEE Std 1003.1 (version?)
+// _POSIX_C_SOURCE == 1		IEEE Std 1003.1-1990
+// _POSIX_C_SOURCE == 2		IEEE Std 1003.2-1992
+// _POSIX_C_SOURCE == 199309L	IEEE Std 1003.1b-1993
+// _POSIX_C_SOURCE == 199506L	ISO/IEC 9945-1:1996
+// _POSIX_C_SOURCE == 200112L	IEEE Std 1003.1-2001
+// _POSIX_C_SOURCE == 200809L   IEEE Std 1003.1-2008
+//
+// X/Open macros:
+// _XOPEN_SOURCE		System Interfaces and Headers, Issue 4, Ver 2
+// _XOPEN_SOURCE_EXTENDED == 1	XSH4.2 UNIX extensions
+// _XOPEN_SOURCE == 500		System Interfaces and Headers, Issue 5
+// _XOPEN_SOURCE == 520		Networking Services (XNS), Issue 5.2
+// _XOPEN_SOURCE == 600		IEEE Std 1003.1-2001, XSI option
+// _XOPEN_SOURCE == 700		IEEE Std 1003.1-2008, XSI option
+//
+// NetBSD macros:
+// _NETBSD_SOURCE == 1		Make all NetBSD features available.
+//
+// If more than one of these "major" feature-test macros is defined,
+// then the set of facilities provided (and namespace used) is the
+// union of that specified by the relevant standards, and in case of
+// conflict, the earlier standard in the above list has precedence (so
+// if both _POSIX_C_SOURCE and _NETBSD_SOURCE are defined, the version
+// of rename() that's used is the POSIX one).  If none of the "major"
+// feature-test macros is defined, _NETBSD_SOURCE is assumed.
+//
+// There are also "minor" feature-test macros, which enable extra
+// functionality in addition to some base standard.  They should be
+// defined along with one of the "major" macros.  The "minor" macros
+// are:
+//
+// _REENTRANT
+// _ISOC99_SOURCE

+// Written by Klaus Klein <kleink@NetBSD.org>, February 2, 1998.
+// Public domain.
+//
+// NOTE: Do not protect this header against multiple inclusion.  Doing
+// so can have subtle side-effects due to header file inclusion order
+// and testing of e.g. _POSIX_SOURCE vs. _POSIX_C_SOURCE.  Instead,
+// protect each CPP macro that we want to supply.
+
+// Feature-test macros are defined by several standards, and allow an
+// application to specify what symbols they want the system headers to
+// expose, and hence what standard they want them to conform to.
+// There are two classes of feature-test macros.  The first class
+// specify complete standards, and if one of these is defined, header
+// files will try to conform to the relevant standard.  They are:
+//
+// ANSI macros:
+// _ANSI_SOURCE			ANSI C89
+//
+// POSIX macros:
+// _POSIX_SOURCE == 1		IEEE Std 1003.1 (version?)
+// _POSIX_C_SOURCE == 1		IEEE Std 1003.1-1990
+// _POSIX_C_SOURCE == 2		IEEE Std 1003.2-1992
+// _POSIX_C_SOURCE == 199309L	IEEE Std 1003.1b-1993
+// _POSIX_C_SOURCE == 199506L	ISO/IEC 9945-1:1996
+// _POSIX_C_SOURCE == 200112L	IEEE Std 1003.1-2001
+// _POSIX_C_SOURCE == 200809L   IEEE Std 1003.1-2008
+//
+// X/Open macros:
+// _XOPEN_SOURCE		System Interfaces and Headers, Issue 4, Ver 2
+// _XOPEN_SOURCE_EXTENDED == 1	XSH4.2 UNIX extensions
+// _XOPEN_SOURCE == 500		System Interfaces and Headers, Issue 5
+// _XOPEN_SOURCE == 520		Networking Services (XNS), Issue 5.2
+// _XOPEN_SOURCE == 600		IEEE Std 1003.1-2001, XSI option
+// _XOPEN_SOURCE == 700		IEEE Std 1003.1-2008, XSI option
+//
+// NetBSD macros:
+// _NETBSD_SOURCE == 1		Make all NetBSD features available.
+//
+// If more than one of these "major" feature-test macros is defined,
+// then the set of facilities provided (and namespace used) is the
+// union of that specified by the relevant standards, and in case of
+// conflict, the earlier standard in the above list has precedence (so
+// if both _POSIX_C_SOURCE and _NETBSD_SOURCE are defined, the version
+// of rename() that's used is the POSIX one).  If none of the "major"
+// feature-test macros is defined, _NETBSD_SOURCE is assumed.
+//
+// There are also "minor" feature-test macros, which enable extra
+// functionality in addition to some base standard.  They should be
+// defined along with one of the "major" macros.  The "minor" macros
+// are:
+//
+// _REENTRANT
+// _ISOC99_SOURCE
+// _ISOC11_SOURCE
+// _LARGEFILE_SOURCE		Large File Support
+//		<http://ftp.sas.com/standards/large.file/x_open.20Mar96.html>
+
+// Definitions for byte order, according to byte significance from low
+// address to high.

+// Public domain.
+//
+// NOTE: Do not protect this header against multiple inclusion.  Doing
+// so can have subtle side-effects due to header file inclusion order
+// and testing of e.g. _POSIX_SOURCE vs. _POSIX_C_SOURCE.  Instead,
+// protect each CPP macro that we want to supply.
+
+// Feature-test macros are defined by several standards, and allow an
+// application to specify what symbols they want the system headers to
+// expose, and hence what standard they want them to conform to.
+// There are two classes of feature-test macros.  The first class
+// specify complete standards, and if one of these is defined, header
+// files will try to conform to the relevant standard.  They are:
+//
+// ANSI macros:
+// _ANSI_SOURCE			ANSI C89
+//
+// POSIX macros:
+// _POSIX_SOURCE == 1		IEEE Std 1003.1 (version?)
+// _POSIX_C_SOURCE == 1		IEEE Std 1003.1-1990
+// _POSIX_C_SOURCE == 2		IEEE Std 1003.2-1992
+// _POSIX_C_SOURCE == 199309L	IEEE Std 1003.1b-1993
+// _POSIX_C_SOURCE == 199506L	ISO/IEC 9945-1:1996
+// _POSIX_C_SOURCE == 200112L	IEEE Std 1003.1-2001
+// _POSIX_C_SOURCE == 200809L   IEEE Std 1003.1-2008
+//
+// X/Open macros:
+// _XOPEN_SOURCE		System Interfaces and Headers, Issue 4, Ver 2
+// _XOPEN_SOURCE_EXTENDED == 1	XSH4.2 UNIX extensions
+// _XOPEN_SOURCE == 500		System Interfaces and Headers, Issue 5
+// _XOPEN_SOURCE == 520		Networking Services (XNS), Issue 5.2
+// _XOPEN_SOURCE == 600		IEEE Std 1003.1-2001, XSI option
+// _XOPEN_SOURCE == 700		IEEE Std 1003.1-2008, XSI option
+//
+// NetBSD macros:
+// _NETBSD_SOURCE == 1		Make all NetBSD features available.
+//
+// If more than one of these "major" feature-test macros is defined,
+// then the set of facilities provided (and namespace used) is the
+// union of that specified by the relevant standards, and in case of
+// conflict, the earlier standard in the above list has precedence (so
+// if both _POSIX_C_SOURCE and _NETBSD_SOURCE are defined, the version
+// of rename() that's used is the POSIX one).  If none of the "major"
+// feature-test macros is defined, _NETBSD_SOURCE is assumed.
+//
+// There are also "minor" feature-test macros, which enable extra
+// functionality in addition to some base standard.  They should be
+// defined along with one of the "major" macros.  The "minor" macros
+// are:
+//
+// _REENTRANT
+// _ISOC99_SOURCE
+// _ISOC11_SOURCE
+// _LARGEFILE_SOURCE		Large File Support
+//		<http://ftp.sas.com/standards/large.file/x_open.20Mar96.html>

+// Feature-test macros are defined by several standards, and allow an
+// application to specify what symbols they want the system headers to
+// expose, and hence what standard they want them to conform to.
+// There are two classes of feature-test macros.  The first class
+// specify complete standards, and if one of these is defined, header
+// files will try to conform to the relevant standard.  They are:
+//
+// ANSI macros:
+// _ANSI_SOURCE			ANSI C89

+// Feature-test macros are defined by several standards, and allow an

+// There are two classes of feature-test macros.  The first class

+// ANSI macros:

+//
+// POSIX macros:
+// _POSIX_SOURCE == 1		IEEE Std 1003.1 (version?)
+// _POSIX_C_SOURCE == 1		IEEE Std 1003.1-1990
+// _POSIX_C_SOURCE == 2		IEEE Std 1003.2-1992

+// _POSIX_C_SOURCE == 200112L	IEEE Std 1003.1-2001
+// _POSIX_C_SOURCE == 200809L   IEEE Std 1003.1-2008
+//
+// X/Open macros:
+// _XOPEN_SOURCE		System Interfaces and Headers, Issue 4, Ver 2
+// _XOPEN_SOURCE_EXTENDED == 1	XSH4.2 UNIX extensions
+// _XOPEN_SOURCE == 500		System Interfaces and Headers, Issue 5
+// _XOPEN_SOURCE == 520		Networking Services (XNS), Issue 5.2
+// _XOPEN_SOURCE == 600		IEEE Std 1003.1-2001, XSI option
+// _XOPEN_SOURCE == 700		IEEE Std 1003.1-2008, XSI option
+//
+// NetBSD macros:
+// _NETBSD_SOURCE == 1		Make all NetBSD features available.
+//
+// If more than one of these "major" feature-test macros is defined,
+// then the set of facilities provided (and namespace used) is the
+// union of that specified by the relevant standards, and in case of
+// conflict, the earlier standard in the above list has precedence (so
+// if both _POSIX_C_SOURCE and _NETBSD_SOURCE are defined, the version
+// of rename() that's used is the POSIX one).  If none of the "major"
+// feature-test macros is defined, _NETBSD_SOURCE is assumed.
+//
+// There are also "minor" feature-test macros, which enable extra
+// functionality in addition to some base standard.  They should be
+// defined along with one of the "major" macros.  The "minor" macros

+// Public domain.
+//
+// NOTE: Do not protect this header against multiple inclusion.  Doing
+// so can have subtle side-effects due to header file inclusion order
+// and testing of e.g. _POSIX_SOURCE vs. _POSIX_C_SOURCE.  Instead,
+// protect each CPP macro that we want to supply.
+
+// Feature-test macros are defined by several standards, and allow an
+// application to specify what symbols they want the system headers to
+// expose, and hence what standard they want them to conform to.
+// There are two classes of feature-test macros.  The first class
+// specify complete standards, and if one of these is defined, header
+// files will try to conform to the relevant standard.  They are:
+//
+// ANSI macros:
+// _ANSI_SOURCE			ANSI C89
+//
+// POSIX macros:
+// _POSIX_SOURCE == 1		IEEE Std 1003.1 (version?)
+// _POSIX_C_SOURCE == 1		IEEE Std 1003.1-1990
+// _POSIX_C_SOURCE == 2		IEEE Std 1003.2-1992
+// _POSIX_C_SOURCE == 199309L	IEEE Std 1003.1b-1993
+// _POSIX_C_SOURCE == 199506L	ISO/IEC 9945-1:1996
+// _POSIX_C_SOURCE == 200112L	IEEE Std 1003.1-2001
+// _POSIX_C_SOURCE == 200809L   IEEE Std 1003.1-2008
+//
+// X/Open macros:
+// _XOPEN_SOURCE		System Interfaces and Headers, Issue 4, Ver 2
+// _XOPEN_SOURCE_EXTENDED == 1	XSH4.2 UNIX extensions
+// _XOPEN_SOURCE == 500		System Interfaces and Headers, Issue 5
+// _XOPEN_SOURCE == 520		Networking Services (XNS), Issue 5.2
+// _XOPEN_SOURCE == 600		IEEE Std 1003.1-2001, XSI option
+// _XOPEN_SOURCE == 700		IEEE Std 1003.1-2008, XSI option
+//
+// NetBSD macros:
+// _NETBSD_SOURCE == 1		Make all NetBSD features available.
+//
+// If more than one of these "major" feature-test macros is defined,
+// then the set of facilities provided (and namespace used) is the
+// union of that specified by the relevant standards, and in case of
+// conflict, the earlier standard in the above list has precedence (so
+// if both _POSIX_C_SOURCE and _NETBSD_SOURCE are defined, the version
+// of rename() that's used is the POSIX one).  If none of the "major"
+// feature-test macros is defined, _NETBSD_SOURCE is assumed.
+//
+// There are also "minor" feature-test macros, which enable extra
+// functionality in addition to some base standard.  They should be
+// defined along with one of the "major" macros.  The "minor" macros
+// are:
+//
+// _REENTRANT
+// _ISOC99_SOURCE
+// _ISOC11_SOURCE
+// _LARGEFILE_SOURCE		Large File Support
+//		<http://ftp.sas.com/standards/large.file/x_open.20Mar96.html>

+// Written by J.T. Conklin <jtc@wimsey.com> 01/17/95.
+// Public domain.
+
+// Macro to test if we're using a specific version of gcc or later.
+
+// The __CONCAT macro is used to concatenate parts of symbol names, e.g.
+// with "#define OLD(foo) __CONCAT(old,foo)", OLD(foo) produces oldfoo.
+// The __CONCAT macro is a bit tricky -- make sure you don't put spaces
+// in between its arguments.  Do not use __CONCAT on double-quoted strings,
+// such as those from the __STRING macro: to concatenate strings just put
+// them next to each other.
+
+// GCC1 and some versions of GCC2 declare dead (non-returning) and
+// pure (no side effects) functions using "volatile" and "const";
+// unfortunately, these then cause warnings under "-ansi -pedantic".
+// GCC >= 2.5 uses the __attribute__((attrs)) style.  All of these
+// work for GNU C++ (modulo a slight glitch in the C++ grammar in
+// the distribution version of 2.5.5).
+
+// __returns_twice makes the compiler not assume the function
+// only returns once.  This affects registerisation of variables:
+// even local variables need to be in memory across such a call.
+// Example: setjmp()
+
+// __only_inline makes the compiler only use this function definition
+// for inlining; references that can't be inlined will be left as
+// external references instead of generating a local copy.  The
+// matching library should include a simple extern definition for
+// the function to handle those references.  c.f. ctype.h
+
+// GNU C version 2.96 adds explicit branch prediction so that
+// the CPU back-end can hint the processor and also so that
+// code blocks can be reordered such that the predicted path
+// sees a more linear flow, thus improving cache behavior, etc.
+//
+// The following two macros provide us with a way to utilize this
+// compiler feature.  Use __predict_true() if you expect the expression
+// to evaluate to true, and __predict_false() if you expect the
+// expression to evaluate to false.
+//
+// A few notes about usage:
+//
+//	* Generally, __predict_false() error condition checks (unless
+//	  you have some _strong_ reason to do otherwise, in which case
+//	  document it), and/or __predict_true() `no-error' condition
+//	  checks, assuming you want to optimize for the no-error case.
+//
+//	* Other than that, if you don't know the likelihood of a test
+//	  succeeding from empirical or other `hard' evidence, don't
+//	  make predictions.
+//
+//	* These are meant to be used in places that are run `a lot'.
+//	  It is wasteful to make predictions in code that is run
+//	  seldomly (e.g. at subsystem initialization time) as the
+//	  basic block reordering that this affects can often generate
+//	  larger code.
+
+// Delete pseudo-keywords wherever they are not available or needed.
+
+// The __packed macro indicates that a variable or structure members
+// should have the smallest possible alignment, despite any host CPU
+// alignment requirements.
+//
+// The __aligned(x) macro specifies the minimum alignment of a
+// variable or structure.
+//
+// These macros together are useful for describing the layout and
+// alignment of messages exchanged with hardware or other systems.
+
+// "The nice thing about standards is that there are so many to choose from."
+// There are a number of "feature test macros" specified by (different)
+// standards that determine which interfaces and types the header files
+// should expose.
+//
+// Because of inconsistencies in these macros, we define our own
+// set in the private name space that end in _VISIBLE.  These are
+// always defined and so headers can test their values easily.
+// Things can get tricky when multiple feature macros are defined.
+// We try to take the union of all the features requested.
+//
+// The following macros are guaranteed to have a value after cdefs.h
+// has been included:
+//	__POSIX_VISIBLE
+//	__XPG_VISIBLE
+//	__ISO_C_VISIBLE
+//	__BSD_VISIBLE
+
+// X/Open Portability Guides and Single Unix Specifications.
+// _XOPEN_SOURCE				XPG3
+// _XOPEN_SOURCE && _XOPEN_VERSION = 4		XPG4
+// _XOPEN_SOURCE && _XOPEN_SOURCE_EXTENDED = 1	XPG4v2
+// _XOPEN_SOURCE == 500				XPG5
+// _XOPEN_SOURCE == 520				XPG5v2
+// _XOPEN_SOURCE == 600				POSIX 1003.1-2001 with XSI
+// _XOPEN_SOURCE == 700				POSIX 1003.1-2008 with XSI
+//
+// The XPG spec implies a specific value for _POSIX_C_SOURCE.
+
+// POSIX macros, these checks must follow the XOPEN ones above.
+//
+// _POSIX_SOURCE == 1		1003.1-1988 (superseded by _POSIX_C_SOURCE)
+// _POSIX_C_SOURCE == 1		1003.1-1990
+// _POSIX_C_SOURCE == 2		1003.2-1992
+// _POSIX_C_SOURCE == 199309L	1003.1b-1993
+// _POSIX_C_SOURCE == 199506L   1003.1c-1995, 1003.1i-1995,
+//				and the omnibus ISO/IEC 9945-1:1996
+// _POSIX_C_SOURCE == 200112L   1003.1-2001
+// _POSIX_C_SOURCE == 200809L   1003.1-2008
+//
+// The POSIX spec implies a specific value for __ISO_C_VISIBLE, though
+// this may be overridden by the _ISOC99_SOURCE macro later.
+
+// _ANSI_SOURCE means to expose ANSI C89 interfaces only.
+// If the user defines it in addition to one of the POSIX or XOPEN
+// macros, assume the POSIX/XOPEN macro(s) should take precedence.
+
+// _ISOC99_SOURCE, _ISOC11_SOURCE, __STDC_VERSION__, and __cplusplus
+// override any of the other macros since they are non-exclusive.
+
+// Finally deal with BSD-specific interfaces that are not covered
+// by any standards.  We expose these when none of the POSIX or XPG
+// macros is defined or if the user explicitly asks for them.

+// Written by J.T. Conklin <jtc@wimsey.com> 01/17/95.
+// Public domain.
+
+// Macro to test if we're using a specific version of gcc or later.
+
+// The __CONCAT macro is used to concatenate parts of symbol names, e.g.
+// with "#define OLD(foo) __CONCAT(old,foo)", OLD(foo) produces oldfoo.
+// The __CONCAT macro is a bit tricky -- make sure you don't put spaces
+// in between its arguments.  Do not use __CONCAT on double-quoted strings,
+// such as those from the __STRING macro: to concatenate strings just put
+// them next to each other.
+
+// GCC1 and some versions of GCC2 declare dead (non-returning) and
+// pure (no side effects) functions using "volatile" and "const";
+// unfortunately, these then cause warnings under "-ansi -pedantic".
+// GCC >= 2.5 uses the __attribute__((attrs)) style.  All of these
+// work for GNU C++ (modulo a slight glitch in the C++ grammar in
+// the distribution version of 2.5.5).
+
+// __returns_twice makes the compiler not assume the function
+// only returns once.  This affects registerisation of variables:
+// even local variables need to be in memory across such a call.
+// Example: setjmp()
+
+// __only_inline makes the compiler only use this function definition
+// for inlining; references that can't be inlined will be left as
+// external references instead of generating a local copy.  The
+// matching library should include a simple extern definition for
+// the function to handle those references.  c.f. ctype.h
+
+// GNU C version 2.96 adds explicit branch prediction so that
+// the CPU back-end can hint the processor and also so that
+// code blocks can be reordered such that the predicted path
+// sees a more linear flow, thus improving cache behavior, etc.
+//
+// The following two macros provide us with a way to utilize this
+// compiler feature.  Use __predict_true() if you expect the expression
+// to evaluate to true, and __predict_false() if you expect the
+// expression to evaluate to false.
+//
+// A few notes about usage:
+//
+//	* Generally, __predict_false() error condition checks (unless
+//	  you have some _strong_ reason to do otherwise, in which case
+//	  document it), and/or __predict_true() `no-error' condition
+//	  checks, assuming you want to optimize for the no-error case.
+//
+//	* Other than that, if you don't know the likelihood of a test
+//	  succeeding from empirical or other `hard' evidence, don't
+//	  make predictions.
+//
+//	* These are meant to be used in places that are run `a lot'.
+//	  It is wasteful to make predictions in code that is run
+//	  seldomly (e.g. at subsystem initialization time) as the
+//	  basic block reordering that this affects can often generate
+//	  larger code.
+
+// Delete pseudo-keywords wherever they are not available or needed.
+
+// The __packed macro indicates that a variable or structure members
+// should have the smallest possible alignment, despite any host CPU
+// alignment requirements.
+//
+// The __aligned(x) macro specifies the minimum alignment of a
+// variable or structure.
+//
+// These macros together are useful for describing the layout and
+// alignment of messages exchanged with hardware or other systems.
+
+// "The nice thing about standards is that there are so many to choose from."
+// There are a number of "feature test macros" specified by (different)
+// standards that determine which interfaces and types the header files
+// should expose.
+//
+// Because of inconsistencies in these macros, we define our own
+// set in the private name space that end in _VISIBLE.  These are
+// always defined and so headers can test their values easily.
+// Things can get tricky when multiple feature macros are defined.
+// We try to take the union of all the features requested.
+//
+// The following macros are guaranteed to have a value after cdefs.h
+// has been included:
+//	__POSIX_VISIBLE
+//	__XPG_VISIBLE
+//	__ISO_C_VISIBLE
+//	__BSD_VISIBLE
+
+// X/Open Portability Guides and Single Unix Specifications.
+// _XOPEN_SOURCE				XPG3

+// _XOPEN_SOURCE && _XOPEN_SOURCE_EXTENDED = 1	XPG4v2

+// _XOPEN_SOURCE == 700				POSIX 1003.1-2008 with XSI
+//
+// The XPG spec implies a specific value for _POSIX_C_SOURCE.
+
+// POSIX macros, these checks must follow the XOPEN ones above.
+//
+// _POSIX_SOURCE == 1		1003.1-1988 (superseded by _POSIX_C_SOURCE)
+// _POSIX_C_SOURCE == 1		1003.1-1990

+// _POSIX_C_SOURCE == 200809L   1003.1-2008
+//
+// The POSIX spec implies a specific value for __ISO_C_VISIBLE, though
+// this may be overridden by the _ISOC99_SOURCE macro later.
+
+// _ANSI_SOURCE means to expose ANSI C89 interfaces only.
+// If the user defines it in addition to one of the POSIX or XOPEN
+// macros, assume the POSIX/XOPEN macro(s) should take precedence.
+
+// _ISOC99_SOURCE, _ISOC11_SOURCE, __STDC_VERSION__, and __cplusplus
+// override any of the other macros since they are non-exclusive.
+
+// Finally deal with BSD-specific interfaces that are not covered
+// by any standards.  We expose these when none of the POSIX or XPG
+// macros is defined or if the user explicitly asks for them.

+// Macro to test if we're using a specific version of gcc or later.
+
+// The __CONCAT macro is used to concatenate parts of symbol names, e.g.
+// with "#define OLD(foo) __CONCAT(old,foo)", OLD(foo) produces oldfoo.
+// The __CONCAT macro is a bit tricky -- make sure you don't put spaces
+// in between its arguments.  Do not use __CONCAT on double-quoted strings,
+// such as those from the __STRING macro: to concatenate strings just put
+// them next to each other.
+
+// GCC1 and some versions of GCC2 declare dead (non-returning) and
+// pure (no side effects) functions using "volatile" and "const";
+// unfortunately, these then cause warnings under "-ansi -pedantic".
+// GCC >= 2.5 uses the __attribute__((attrs)) style.  All of these
+// work for GNU C++ (modulo a slight glitch in the C++ grammar in
+// the distribution version of 2.5.5).
+
+// __returns_twice makes the compiler not assume the function
+// only returns once.  This affects registerisation of variables:
+// even local variables need to be in memory across such a call.
+// Example: setjmp()
+
+// __only_inline makes the compiler only use this function definition
+// for inlining; references that can't be inlined will be left as
+// external references instead of generating a local copy.  The
+// matching library should include a simple extern definition for
+// the function to handle those references.  c.f. ctype.h
+
+// GNU C version 2.96 adds explicit branch prediction so that
+// the CPU back-end can hint the processor and also so that
+// code blocks can be reordered such that the predicted path
+// sees a more linear flow, thus improving cache behavior, etc.
+//
+// The following two macros provide us with a way to utilize this
+// compiler feature.  Use __predict_true() if you expect the expression
+// to evaluate to true, and __predict_false() if you expect the
+// expression to evaluate to false.
+//
+// A few notes about usage:
+//
+//	* Generally, __predict_false() error condition checks (unless
+//	  you have some _strong_ reason to do otherwise, in which case
+//	  document it), and/or __predict_true() `no-error' condition
+//	  checks, assuming you want to optimize for the no-error case.
+//
+//	* Other than that, if you don't know the likelihood of a test
+//	  succeeding from empirical or other `hard' evidence, don't
+//	  make predictions.
+//
+//	* These are meant to be used in places that are run `a lot'.
+//	  It is wasteful to make predictions in code that is run
+//	  seldomly (e.g. at subsystem initialization time) as the
+//	  basic block reordering that this affects can often generate
+//	  larger code.
+
+// Delete pseudo-keywords wherever they are not available or needed.
+
+// The __packed macro indicates that a variable or structure members
+// should have the smallest possible alignment, despite any host CPU
+// alignment requirements.
+//
+// The __aligned(x) macro specifies the minimum alignment of a
+// variable or structure.
+//
+// These macros together are useful for describing the layout and
+// alignment of messages exchanged with hardware or other systems.
+
+// "The nice thing about standards is that there are so many to choose from."
+// There are a number of "feature test macros" specified by (different)
+// standards that determine which interfaces and types the header files
+// should expose.
+//
+// Because of inconsistencies in these macros, we define our own
+// set in the private name space that end in _VISIBLE.  These are
+// always defined and so headers can test their values easily.
+// Things can get tricky when multiple feature macros are defined.
+// We try to take the union of all the features requested.
+//
+// The following macros are guaranteed to have a value after cdefs.h
+// has been included:
+//	__POSIX_VISIBLE
+//	__XPG_VISIBLE
+//	__ISO_C_VISIBLE
+//	__BSD_VISIBLE
+
+// X/Open Portability Guides and Single Unix Specifications.

+// _XOPEN_SOURCE == 700				POSIX 1003.1-2008 with XSI
+//
+// The XPG spec implies a specific value for _POSIX_C_SOURCE.
+
+// POSIX macros, these checks must follow the XOPEN ones above.
+//
+// _POSIX_SOURCE == 1		1003.1-1988 (superseded by _POSIX_C_SOURCE)
+// _POSIX_C_SOURCE == 1		1003.1-1990

+// _POSIX_C_SOURCE == 200809L   1003.1-2008
+//
+// The POSIX spec implies a specific value for __ISO_C_VISIBLE, though
+// this may be overridden by the _ISOC99_SOURCE macro later.
+
+// _ANSI_SOURCE means to expose ANSI C89 interfaces only.
+// If the user defines it in addition to one of the POSIX or XOPEN
+// macros, assume the POSIX/XOPEN macro(s) should take precedence.
+
+// _ISOC99_SOURCE, _ISOC11_SOURCE, __STDC_VERSION__, and __cplusplus
+// override any of the other macros since they are non-exclusive.
+
+// Finally deal with BSD-specific interfaces that are not covered

+// macros is defined or if the user explicitly asks for them.

+// mingw.org's version macros: these make gcc to define
+//    MINGW32_SUPPORTS_MT_EH and to use the _CRT_MT global
+//    and the __mingwthr_key_dtor() function from the MinGW
+//    CRT in its private gthr-win32.h header.

+// MS does not prefix symbols by underscores for 64-bit.
+// As we have to support older gcc version, which are using underscores
+//       as symbol prefix for x64, we have to check here for the user label
+//       prefix defined by gcc.
+
+// Special case nameless struct/union.
+
+// MinGW-w64 has some additional C99 printf/scanf feature support.
