//  Of course this will generally degrade compression (there's no free lunch).

//    _XOPEN_SOURCE	Includes POSIX and XPG things.  Set to 500 if

//
//    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

//
//    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_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

//    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

// 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.

// Any one of these symbols __need_* means that GNU libc
//    wants us just to define one data type.  So don't define
//    the symbols that indicate this file's entire job has been done.

// This avoids lossage on SunOS but only if stdtypes.h comes first.
//    There's no way to win with the other order!  Sun lossage.

// Sequent's header files use _PTRDIFF_T_ in some conflicting way.
//    Just ignore it.

// On VxWorks, <type/vxTypesBase.h> may have defined macros like
//    _TYPE_size_t which will typedef size_t.  fixincludes patched the
//    vxTypesBase.h so that this macro is only defined if _GCC_SIZE_T is
//    not defined, and so that defining this macro defines _GCC_SIZE_T.
//    If we find that the macros are still defined at this point, we must
//    invoke them so that the type is defined as expected.

// In case nobody has defined these types, but we aren't running under
//    GCC 2.00, make sure that __PTRDIFF_TYPE__, __SIZE_TYPE__, and
//    __WCHAR_TYPE__ have reasonable values.  This can happen if the
//    parts of GCC is compiled by an older compiler, that actually
//    include gstddef.h, such as collect2.

// MVS linker does not support external names larger than 8 bytes

//
//     The 'zlib' compression library provides in-memory compression and
//   decompression functions, including integrity checks of the uncompressed data.
//   This version of the library supports only one compression method (deflation)
//   but other algorithms will be added later and will have the same stream
//   interface.
//
//     Compression can be done in a single step if the buffers are large enough,
//   or can be done by repeated calls of the compression function.  In the latter
//   case, the application must provide more input and/or consume the output
//   (providing more output space) before each call.
//
//     The compressed data format used by default by the in-memory functions is
//   the zlib format, which is a zlib wrapper documented in RFC 1950, wrapped
//   around a deflate stream, which is itself documented in RFC 1951.
//
//     The library also supports reading and writing files in gzip (.gz) format
//   with an interface similar to that of stdio using the functions that start
//   with "gz".  The gzip format is different from the zlib format.  gzip is a
//   gzip wrapper, documented in RFC 1952, wrapped around a deflate stream.
//
//     This library can optionally read and write gzip and raw deflate streams in
//   memory as well.
//
//     The zlib format was designed to be compact and fast for use in memory
//   and on communications channels.  The gzip format was designed for single-
//   file compression on file systems, has a larger header than zlib to maintain
//   directory information, and uses a different, slower check method than zlib.
//
//     The library does not install any signal handler.  The decoder checks
//   the consistency of the compressed data, so the library should never crash
//   even in the case of corrupted input.

//      inflateGetHeader() requests that gzip header information be stored in the
//    provided gz_header structure.  inflateGetHeader() may be called after
//    inflateInit2() or inflateReset(), and before the first call of inflate().
//    As inflate() processes the gzip stream, head->done is zero until the header
//    is completed, at which time head->done is set to one.  If a zlib stream is
//    being decoded, then head->done is set to -1 to indicate that there will be
//    no gzip header information forthcoming.  Note that Z_BLOCK or Z_TREES can be
//    used to force inflate() to return immediately after header processing is
//    complete and before any actual data is decompressed.
//
//      The text, time, xflags, and os fields are filled in with the gzip header
//    contents.  hcrc is set to true if there is a header CRC.  (The header CRC
//    was valid if done is set to one.) If extra is not Z_NULL, then extra_max
//    contains the maximum number of bytes to write to extra.  Once done is true,
//    extra_len contains the actual extra field length, and extra contains the
//    extra field, or that field truncated if extra_max is less than extra_len.
//    If name is not Z_NULL, then up to name_max characters are written there,
//    terminated with a zero unless the length is greater than name_max.  If
//    comment is not Z_NULL, then up to comm_max characters are written there,
//    terminated with a zero unless the length is greater than comm_max.  When any
//    of extra, name, or comment are not Z_NULL and the respective field is not
//    present in the header, then that field is set to Z_NULL to signal its
//    absence.  This allows the use of deflateSetHeader() with the returned
//    structure to duplicate the header.  However if those fields are set to
//    allocated memory, then the application will need to save those pointers
//    elsewhere so that they can be eventually freed.
//
//      If inflateGetHeader is not used, then the header information is simply
//    discarded.  The header is always checked for validity, including the header
//    CRC if present.  inflateReset() will reset the process to discard the header
//    information.  The application would need to call inflateGetHeader() again to
//    retrieve the header from the next gzip stream.

//    stream state was inconsistent.

//
//      Initialize the internal stream state for decompression using inflateBack()
//    calls.  The fields zalloc, zfree and opaque in strm must be initialized
//    before the call.  If zalloc and zfree are Z_NULL, then the default library-
//    derived memory allocation routines are used.  windowBits is the base two
//    logarithm of the window size, in the range 8..15.  window is a caller
//    supplied buffer of that size.  Except for special applications where it is
//    assured that deflate was used with small window sizes, windowBits must be 15
//    and a 32K byte window must be supplied to be able to decompress general
//    deflate streams.
//
//      See inflateBack() for the usage of these routines.
//

// Any one of these symbols __need_* means that GNU libc

// This avoids lossage on SunOS but only if stdtypes.h comes first.

// Sequent's header files use _PTRDIFF_T_ in some conflicting way.

// On VxWorks, <type/vxTypesBase.h> may have defined macros like
//    _TYPE_size_t which will typedef size_t.  fixincludes patched the

//    not defined, and so that defining this macro defines _GCC_SIZE_T.
//    If we find that the macros are still defined at this point, we must
//    invoke them so that the type is defined as expected.

// In case nobody has defined these types, but we aren't running under
//    GCC 2.00, make sure that __PTRDIFF_TYPE__, __SIZE_TYPE__, and
//    __WCHAR_TYPE__ have reasonable values.  This can happen if the
