It's an interesting thought. But
  * In order to get the global locale, you would need to do three calls to
      locale_t loc = uselocale (NULL);
      locale_t global = uselocale (LC_GLOBAL_LOCALE);
      uselocale (loc);
  * It won't work, because uselocale does not exist or does not work on some
    of the listed platforms: NetBSD, Haiku, MSVC.
