//
// 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_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.

// 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.
// 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.

//
// _POSIX_V7_ILP32_OFF32 32bit int, long, pointers, and off_t type

// _POSIX_V7_LPBIG_OFFBIG 64bit long and pointers and large off_t type
//
// The macros _POSIX_V6_ILP32_OFF32, _POSIX_V6_ILP32_OFFBIG,
// _POSIX_V6_LP64_OFF32, _POSIX_V6_LPBIG_OFFBIG, _XBS5_ILP32_OFF32,
// _XBS5_ILP32_OFFBIG, _XBS5_LP64_OFF32, and _XBS5_LPBIG_OFFBIG were
// used in previous versions of the Unix standard and are available
// only for compatibility.
// We have 32-bit wide `int', `long int' and pointers and all platforms
// support LFS. -mx32 has 64-bit wide `off_t'.
// -m32 has 32-bit wide `off_t'.
// We optionally provide an environment with the above size but an 64-bit
// side `off_t'. Therefore we don't define _POSIX_V7_ILP32_OFFBIG.
// Environments with 64-bit wide pointers can be provided,
// so these macros aren't defined:
// # undef _POSIX_V7_LP64_OFF64
// # undef _POSIX_V7_LPBIG_OFFBIG
// # undef _POSIX_V6_LP64_OFF64
// # undef _POSIX_V6_LPBIG_OFFBIG

// 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.
