Update.
2001-07-27  Ulrich Drepper  <drepper@redhat.com>

	* iconv/gconv_cache.c (__gconv_compare_alias_cache): New function.
	* iconv/gconv_int.h: Add prototype for __gconv_compare_alias_cache.
	* iconv/gconv_charset.h: Replace __gconv_lookup_alias prototype with
	__gconv_compare_alias prototype.
	* iconv/gconv_db.c (__gconv_lookup_alias): Removed.
	(__gconv_compare_alias): New function.
	* locale/findlocale.c (_nl_find_locale): Ise __gconv_compare_alias
	instead of calling __gconv_lookup_alias twice and compare here.
