  //  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
