12//  Revision History
13//   31 Oct 01  use BOOST_HAS_LONG_LONG to check for "long long" (Jens M.)
14//   16 Apr 01  check LONGLONG_MAX when looking for "long long" (Jens Maurer)
15//   23 Jan 01  prefer "long" over "int" for int32_t and intmax_t (Jens Maurer)
16//   12 Nov 00  Merged <boost/stdint.h> (Jens Maurer)
17//   23 Sep 00  Added INTXX_C macro support (John Maddock).
18//   22 Sep 00  Better 64-bit support (John Maddock)
19//   29 Jun 00  Reimplement to avoid including stdint.h within namespace boost
20//    8 Aug 99  Initial version (Beman Dawes)
