From 6570e194e60822d81d6df31e260985e6a13b0f2a Mon Sep 17 00:00:00 2001
From: Ulrich Drepper <drepper@redhat.com>
Date: Fri, 20 Aug 1999 19:52:54 +0000
Subject: Update.

	* intl/gettextP.h (struct loaded_domain): Add conv element.
	* intl/dcgettext.c (find_msg): Rename to _nl_find_msg and make public.
	Instead of returning found message directly convert it using iconv
	if a conversion was found when opening the file.
	* intl/loadinfo.h: Protect against multiple inclusion.
	Declare _nl_find_msg.
	* intl/loadmsgcat.c (_nl_load_domain): Try to determine charset used
	in the message file and if necessary find approrpiate
	conversion to match currently selected charset.
