Update.

2003-02-21  Ulrich Drepper  <drepper@redhat.com>

	* sysdeps/unix/sysv/linux/i386/getuid.c: Use INTERNAL_SYSCALL and do
	not chechk for errors (unless testing for 32bit variant).
	* sysdeps/unix/sysv/linux/i386/getgid.c: Likewise.
	* sysdeps/unix/sysv/linux/i386/geteuid.c: Likewise.
	* sysdeps/unix/sysv/linux/i386/getegid.c: Likewise.
