New description:

 On Windows, compiling with mingw32, __STDC_LIMIT_MACROS macro is redefined
 if it was already defined.

 This macro is defined in boost/config/platform/win32.hpp by


 {{{
 #if defined(__MINGW32__) && ((__MINGW32_MAJOR_VERSION > 2) ||
 ((__MINGW32_MAJOR_VERSION == 2) && (__MINGW32_MINOR_VERSION >= 0)))
 #  define BOOST_HAS_STDINT_H
 #  define __STDC_LIMIT_MACROS
 #  define BOOST_HAS_DIRENT_H
 #  define BOOST_HAS_UNISTD_H
 #endif
 }}}


 Maybe it can be changed to:


 {{{
 #if defined(__MINGW32__) && ((__MINGW32_MAJOR_VERSION > 2) ||
 ((__MINGW32_MAJOR_VERSION == 2) && (__MINGW32_MINOR_VERSION >= 0)))
 #  define BOOST_HAS_STDINT_H
 #  if !defined(__STDC_LIMIT_MACROS)
 #    define __STDC_LIMIT_MACROS
 #  endif
 #  define BOOST_HAS_DIRENT_H
 #  define BOOST_HAS_UNISTD_H
 #endif
 }}}
