From 3bbea7af281dcd8ebd320a036fa56f5883815159 Mon Sep 17 00:00:00 2001
From: Ian Lance Taylor <ian@airs.com>
Date: Wed, 28 Sep 1994 19:53:22 +0000
Subject: [PATCH] 	* Makefile.in (arparse.c): Don't ignore errors from
 mv. 	(sysinfo.c): Likewise.  Also, depend upon arparse.c, to prevent a 
 parallel make from trying to build both arparse.c and sysinfo.c 
 simultaneously. 	(nlmheader.c): Similar change. 	(arparse.h): Separate
 target from arparse.c, so that a parallel 	make does not try to build
 both at once.  Depend upon arparse.c. 	(sysinfo.h): Similar change.
