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. 2000-04-27 Bruno Haible <haible@clisp.cons.org>
