//  Revision History

//   31 Oct 01  use BOOST_HAS_LONG_LONG to check for "long long" (Jens M.)

//   16 Apr 01  check LONGLONG_MAX when looking for "long long" (Jens Maurer)

//   23 Jan 01  prefer "long" over "int" for int32_t and intmax_t (Jens Maurer)

//   12 Nov 00  Merged <boost/stdint.h> (Jens Maurer)

//   23 Sep 00  Added INTXX_C macro support (John Maddock).

//   22 Sep 00  Better 64-bit support (John Maddock)

//   29 Jun 00  Reimplement to avoid including stdint.h within namespace boost

//    8 Aug 99  Initial version (Beman Dawes)

// Since we always define the INT#_C macros as per C++0x,

// define __STDC_CONSTANT_MACROS so that <stdint.h> does the right

// thing if possible, and so that the user knows that the macros

// are actually defined as per C99.

// Note that GLIBC is a bit inconsistent about whether int64_t is defined or not

// depending upon what headers happen to have been included first...

// so we disable use of stdint.h when GLIBC does not define __GLIBC_HAVE_LONG_LONG.

// See https://svn.boost.org/trac/boost/ticket/3548 and http://sources.redhat.com/bugzilla/show_bug.cgi?id=10990
