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.
