warning in wchar.h

[Phillip Susi]

Hello.  I am running egcs 2.95.2, and I noticed that I get a warning in
wchar.h because it seems to declare _wstat(), wich takes a struct _stat *,
but struct _stat is not defined, because wchar.h does not include
sys/stat.h.  I think that if wchar.h depends on sys/stat.h, it should
include it.
