From 5e473a71467d30b51faadb7b5ae4305abc0a16d7 Mon Sep 17 00:00:00 2001
From: Ulrich Drepper <drepper@redhat.com>
Date: Thu, 9 Aug 2001 00:11:12 +0000
Subject: update.

	* libio/wfileops.c (_IO_wfile_underflow): Remove incorrect test
	for possible conversion using __codecvt_do_in.
	* libio/Makefile (tests): Add tst-fgetws.
	* libio/tst-fgetws.c: New file.

	* libio/iofgetws.c: Use _IO_ferror_unlocked macros instead of
	coding the test here.
