On Posix, it seems that the following does the trick:

  /* get current locale */
  oldloc = uselocale((locale_t)0);

  /* set new locale */
  loc = newlocale(LC_ALL_MASK, "C", NULL);
 uselocale(loc);
 freelocale(loc);

  /* restore previous locale */
  uselocale(oldloc);


For Windows, I could not figure out how to set a "C" locale with its
"SetThreadLocale"...
