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.
