/* Older glibc require a wint_t from <stddef.h> (when requested
   by __need_wint_t, as otherwise stddef.h isn't allowed to
   define this type).   Note that this must be outside the normal
   _STDDEF_H guard, so that it works even when we've included the file
   already (without requiring wint_t).  Some other libs define _WINT_T
   if they've already provided that type, so we can use that as guard.
   TCC defines __WINT_TYPE__ for us.  */
