Update.

2000-07-05  Ulrich Drepper  <drepper@redhat.com>

	* locale/loadlocale.c (_nl_unload_locale): Add cast to avoid warning.

	* locale/programs/ld-collate.c (collate_output): Also write out the
	collation sequence values and the wide character string for the
	collation symbol table.

	* posix/fnmatch.c: Include "../locale/elem-hash.h".
	* posix/fnmatch_loop.c: Implement collating symbol handling.
	* posix/tst-fnmatch.input: Add more tests, especially for collating
	symbol handling.

	* posix/regex.c: Fix comment.
