From 3d4ac1ec92d8b9fce3dfa9cfa0ba030994f17744 Mon Sep 17 00:00:00 2001
From: Ulrich Drepper <drepper@redhat.com>
Date: Mon, 28 Aug 2000 03:51:40 +0000
Subject: Update.

	* locale/programs/ld-collate.c (insert_weights): Also update
	backpointer of next element.
	(collate_read): Allow definition of new collation symbols in stage 2.
	Symbol after reorder-after can be UCS4 value.
	Allow reordering of collation symbols and elements.
	Do not only move reorder entry in new position.  Instead call
	insert_weight to do this and read the weights.
