/* 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.
