Update.

2000-04-26  Ulrich Drepper  <drepper@redhat.com>

	* iconv/gconv_simple.c (utf8_internal_loop): Correctly reconstruct
	stored character in state in UNPACK_BYTES macro.
	* iconv/loop.c (SINGLE(LOOPFCT)): Make it actually work.  Correct
	test for available characters, handle result of BODY code correctly.
	* localedata/Makefile (test-srcs): Add tst-mbswcs1.
	(distribute): Add tst-mbswcs.sh.
	Add rule to run tst-mbswcs.sh.
	* localedata/tst-mbswcs.sh: New file.
	* localedata/tst-mbswcs1.c: New file.

2000-04-26  Jakub Jelinek  <jakub@redhat.com>

	* nis/nis_callback.c (__nis_create_callback): Do failed memory
	allocation fixups centrally, fix __builtin_expect call, return NULL
	on failure, not NIS_NOMEMORY.
