Update.
2002-04-18  Bruno Haible  <bruno@clisp.org>

	* iconvdata/euc-jisx0213.c (EMIT_SHIFT_TO_INIT, BODY for
	FROM_DIRECTION): Make the FROM direction stateless.
	* iconvdata/shift_jisx0213.c (EMIT_SHIFT_TO_INIT, BODY for
	FROM_DIRECTION): Likewise.

	* iconvdata/cvs11643l1.c: Update comments.
	* sysdeps/unix/sysv/linux/s390/s390-64/syscalls.list: Likewise.
