//  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)

Macro definition section:

Define various INTXX_C macros only if

Undefine the macros if __STDC_CONSTANT_MACROS is
not defined and the macros are (cf <cassert>).

Added 23rd September 2000 (John Maddock).
Modified 11th September 2001 to be excluded when
BOOST_HAS_STDINT_H is defined (John Maddock).
