Update.

2002-08-26  Ulrich Drepper  <drepper@redhat.com>

	* libio/Makefile (tests): Add bug-fopena+.
	* libio/bug-fopena+.c: New file.

	* stdio-common/tst-swprintf.c (main): Add casts to avoid warnings.

	* locale/xlocale.c: Fix the last change.  The variable still has
	to end in _data.
	* sysdeps/generic/bits/libc-tsd.h [!(USE_TLS && HAVE___THREAD)]
	(__libc_tsd_set): Add _data prefix to variable name.
