Ulrich Drepper 9eb88290df Update.
2003-03-23  Ulrich Drepper  <drepper@redhat.com>

	* sysdeps/unix/make-syscalls.sh: Recognize 'E' in first position of
	the parameter description to denote no error checking.  Generate
	appropriate pseudo asm code.
	* sysdeps/unix/syscalls.list: Mark getgid, getpid, getuid with 'E'.
	* sysdeps/unix/sysv/linux/syscalls.list: Mark getegid, geteuid,
	getpgrp, and getppid with 'E'.
	* sysdeps/powerpc/powerpc32/sysdep.h: Define PSEUDO_NOERRNO,
	PSEUDO_END_NOERRNO, and ret_NOERRNO.
	* sysdeps/powerpc/powerpc64/sysdep.h: Likewise.
	* sysdeps/unix/sysdep.h: Likewise.
