From 7f4553513cc2e247fa40ba80485f41e942ba6c9b Mon Sep 17 00:00:00 2001
From: Ulrich Drepper <drepper@redhat.com>
Date: Sat, 1 Jul 2000 00:04:28 +0000
Subject: Update.

	* iconv/gconv_trans.c: Test with _NL_CTYPE_TRANSLIT_DEFAULT_MISSING_LEN
	whether this information is available.

	* intl/dcigettext.c (_nl_find_msg): Correct reallocation of
	buffers in case the translation is too large.  Remember allocated
	memory blocks in a list.
	(free_mem): Free memory for translations.

	* intl/tst-gettext.c: Use correct locale.  Improve error messages.

	* locale/programs/ld-ctype.c (ctype_output): If no default_missing
	information is available set the string length to zero.
