Some old glibcs <wctype.h> require <stddef.h> to provide
wint_t, accomodate them.

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 requring wint_t). Some other libs define _WINT_T
if they've already provided that type, so we can use that as guard.
