//  MACRO:         BOOST_HAS_STDINT_H
//  TITLE:         stdint.h
//  DESCRIPTION:   There are no 1998 C++ Standard headers <stdint.h> 
//                 or <cstdint>, although the 1999 C Standard does
//                 include <stdint.h>.
//                 If <stdint.h> is present, <boost/stdint.h> can make
//                 good use of it, so a flag is supplied (signalling
//                 presence; thus the default is not present, conforming
//                 to the current C++ standard).

# if defined(__hpux) || defined(__FreeBSD__) || defined(__IBMCPP__)
#   include <inttypes.h>
# else
#   include <stdint.h>
# endif
