Update.

2000-07-04  Ulrich Drepper  <drepper@redhat.com>

	* crypt/md5-crypt.c (__md5_crypt_r): If buffers for key and salt
	are not aligned to alignof(md5_uint32) do it before calling
	__md5_process_bytes.
	* crypt/md5.c: Make sure buffers are aligned.
	* crypt/md5.h: Likewise.
	Reported by Solar Designer <solar@false.com>.

	* crypt/Makefile: Add dependencies for test programs.

	* Rules: Define LC_ALL=C in environments of all programs we run.

	* intl/tst-gettext.sh (LC_ALL): Define to C and export.

2000-07-03  H.J. Lu  <hjl@gnu.org>

	* locale/programs/ld-ctype.c (ctype_output): The size of iov
	is 2 + elem + offset, not 2 + elem + offset + 2.

2000-07-04  Ulrich Drepper  <drepper@redhat.com>

	* posix/fnmatch_loop.c: Fix two problems uncovered by the new test
	suite.
	* posix/Makefile (tests): Add tst-fnmatch.
	(tst-fnmatch-ENV): Define.
	* posix/tst-fnmatch.c: New file.
	* posix/tst-fnmatch.sh: New file.
