From e0ebcf42c2dfc4e486eb73807806ee813a9a0f50 Mon Sep 17 00:00:00 2001
From: Ian Lance Taylor <ian@airs.com>
Date: Wed, 28 Jan 2009 20:09:18 +0000
Subject: 	* gold.h: Include <cstring> and <stdint.h>. 	* version.cc:
 Include <cstdio>. 	* object.cc (Sized_relobj::do_layout): Initialize
 gc_sd to avoid a 	warning. 	* reduced_debug_output.cc
 (insert_into_vector): Rename from 	Insert_into_vector; change all
 callers.  Use Swap_unaligned to 	avoid aliasing issue; remove union
 since it is unnecessary.
