From 03abc2bd652b49325b5a66563c7a5dbdf158fd39 Mon Sep 17 00:00:00 2001
From: Ian Lance Taylor <ian@airs.com>
Date: Fri, 3 Apr 1998 18:30:15 +0000
Subject: [PATCH] 	* configure.in: Put the tdirs in a file and use
 AC_SUBST_FILE, 	rather than in a shell variable and using AC_SUBST. 
 * Makefile.am (DISTCLEANFILES): Remove ldscripts.  Add tdirs.  
 (distclean-local): New target. 	* configure, Makefile.in: Rebuild.
