Where to get stddef.h and stdarg.h headers?

[Serge Nikulin]

It looks like current distribution lacks 2 headers (stddef.h and stdarg.h).

I've got following report:
----------------
../include/stdio.h:37: stddef.h: No such file or directory
../include/stdio.h:40: stdarg.h: No such file or directory
In file included from ../include/sys/reent.h:14,
                 from ../include/stdio.h:48,
                 from clearerr.c:55:
../include/time.h:30: stddef.h: No such file or directory
----------------

I did not find these files in newlib-cvs-20000615

Cheers
 Serge
