Update.

2000-10-26  Ulrich Drepper  <drepper@redhat.com>

	* posix/Makefile (tests): Add tst-chmod.
	(tst-chmod-ARGS): Define.
	* posix/tst-chmod.c: New file.

	* test-skeleton.c: Before calling user-defined function remove
	parameters from argument list.
	* posix/tst-exec.c: Adjust to this change.
	* posix/tst-spawn.c: Likewise.

	* sysdeps/unix/opendir.c (__opendir): Optimize a bit.  Add
	__builtin_expect.
