__STDC_LIMIT_MACROS can be redefined by boost when using mingw32 — at Version 2

Description (last modified by viboes)

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
