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
