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.
