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.
