2004-06-19  Roland McGrath  <roland@redhat.com>

	* sysdeps/posix/waitid.c (do_waitid) [DO_WAITID]: Define function
	under this macro name instead.
	[NO_DO_WAITID]: Don't define it at all.
	(do_waitid) [WNOWAIT, WEXITED]: If these POSIX.1 waitid flag bits are
	defined, then return ENOTSUP for combinations of selection bits other
	than WEXITED and WEXITED|WSTOPPED, which this version cannot support.

	* posix/tst-waitid.c: New file.
	* posix/Makefile (tests): Add it.
