// 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.
// snaroff@next.com says the NeXT needs this.
// Irix 5.1 needs this.

// In 4.3bsd-net2, machine/ansi.h defines these symbols, which are
//    defined if the corresponding type is *not* defined.
//    FreeBSD-2.1 defines _MACHINE_ANSI_H_ instead of _ANSI_H_

// 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.

// Define this type if we are doing the whole job,

// Define this type if we are doing the whole job,

//    Locale-writers should change this as necessary to

//    and not (wchar_t) -1, for each defined multibyte character.

// Define this type if we are doing the whole job,
//    or if we want this type in particular.

//  In 4.3bsd-net2, leave these undefined to indicate that size_t, etc.

//
//     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.

//    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.
//
//      inflateGetHeader returns Z_OK if success, or Z_STREAM_ERROR if the source
//    stream state was inconsistent.

//
// ZEXTERN int ZEXPORT inflateBackInit OF((z_streamp strm, int windowBits,
//                                         unsigned char FAR *window));
//
//      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.
//
//      inflateBackInit will return Z_OK on success, Z_STREAM_ERROR if any of
//    the parameters are invalid, Z_MEM_ERROR if the internal state could not be
//    allocated, or Z_VERSION_ERROR if the version of the library does not match
//    the version of the header file.
