From 8ad59cabadf0ac64b4b8f0e6690e4689cd44094d Mon Sep 17 00:00:00 2001
From: Tom Yu <tlyu@mit.edu>
Date: Sun, 2 Jul 1995 10:50:04 +0000
Subject: [PATCH] 	* aclocal.m4 (SubdirLibRule): don't recreate DONE if
 list of objs 		is null to avoid re-making lotsa stuff. 	
 (_MAKE_SUBDIRS): really gross sh hack for subdir 		recursion;
 make -[ik] should dtrt now even with broken 		makes (like Ultrix)
 that do sh -ce "rule".  Basically, 		throw an "if" test around the
 recursion line so that even 		if the -e option to sh is set by make,
 an error in a 		subdir below won't cause for loop to exit unless we
 want 		it to.
