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 <ndnboost/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 ndnboost
20// 8 Aug 99 Initial version (Beman Dawes)

28// define __STDC_CONSTANT_MACROS so that <stdint.h> does the right

30// are actually defined as per C99.
