 // 			if >=200809L, all of IEEE 1003.1-2008
 //    _XOPEN_SOURCE	Includes POSIX and XPG things.  Set to 500 if
 // 			Single Unix conformance is wanted, to 600 for the
 // 			sixth revision, to 700 for the seventh revision.
 //    _XOPEN_SOURCE_EXTENDED XPG things and X/Open Unix extensions.

 //
 //    The `-ansi' switch to the GNU C compiler, and standards conformance
 //    options such as `-std=c99', define __STRICT_ANSI__.  If none of
 //    these are defined, or if _DEFAULT_SOURCE is defined, the default is
 //    to have _POSIX_SOURCE set to one and _POSIX_C_SOURCE set to
 //    200809L, as well as enabling miscellaneous functions from BSD and
 //    SVID.  If more than one of these are defined, they accumulate.  For
 //    example __STRICT_ANSI__, _POSIX_SOURCE and _POSIX_C_SOURCE together
 //    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_XOPEN2KXSI     Define XPG6 XSI 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_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.
 
 // 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.

 // 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

 // 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.
 
 // Undefine (also defined in libc-symbols.h).
 // Copies attributes from the declaration or type referenced by
 //    the argument.

 // 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.

 // This file contains shared definitions between Linux architectures

 //    values with different values.
 //
 //    A minimal <bits/fcntl.h> contains just:
 //
 //    struct flock {...}
 //    #ifdef __USE_LARGEFILE64
 //    struct flock64 {...}
 //    #endif

 // open file description locks.
 //
 //    Usually record locks held by a process are released on *any* close and are
 //    not inherited across a fork.
 //
 //    These cmd values will set locks that conflict with process-associated record
 //    locks, but are "owned" by the opened file description, not the process.
 //    This means that they are inherited across fork or clone with CLONE_FILES
 //    like BSD (flock) locks, and they are only released automatically when the
 //    last reference to the the file description against which they were acquired
 //    is put.
 
 // For now, Linux has no separate synchronicity options for read
 //    operations.  We define O_RSYNC therefore as the same as O_SYNC
 //    since this is a superset.
 
 // Values for the second argument to `fcntl'.
 
 // For F_[GET|SET]FD.

 // Operations for BSD flock, also used by the kernel implementation.
 
 // Define some more compatibility macros to be backward compatible with
 //    BSD systems which did not managed to hide these kernel macros.
 
 // Advise to `posix_fadvise'.
 
 // Values for `*at' functions.
 
 // Detect if open needs mode as a third argument (or for openat as a fourth
 //    argument).
 
 // POSIX.1-2001 specifies that these types are defined by <fcntl.h>.
