Update.

2001-03-19  Ulrich Drepper  <drepper@redhat.com>

	* string/Makefile (tests): Add tst-strxfrm.
	* string/tst-strxfrm.c: New file.  Based on a test case by Paul Eggert.
	* string/Depend: New file.

2001-03-19  Paul Eggert  <eggert@twinsun.com>

	* string/strxfrm.c (strxfrm): strxfrm should return 0, not 1,
	when given the empty string in nontrivial locales.
