  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)

  30 // are actually defined as per C99.
