Update.

1998-05-23  Philip Blundell  <Philip.Blundell@pobox.com>

	* sysdeps/unix/sysv/linux/arm/syscalls.list: Add `syscall'.
	* sysdeps/unix/sysv/linux/arm/syscall.S: Deleted.

1998-07-05  Ulrich Drepper  <drepper@cygnus.com>

	* misc/getttyent.c (getttyent): Explicitly lock the FILE and use
	_unlocked functions.

	* inet/ruserpass.c (ruserpass): Use _unlocked functions since this
	is a private FILE.
