From 2de0acc18a98f603f0b3b305f5065cb54cc081b6 Mon Sep 17 00:00:00 2001
From: Ken Raeburn <raeburn@cygnus>
Date: Fri, 6 May 1994 00:12:22 +0000
Subject: [PATCH] * config/mh-lynxrs6k: Renamed from mh-lynxosrs6k, to make it
 unique in 8.3 naming schemes. * configure.in (appdirs): New variable. 
 Currently empty, but will be used in gas distribution.  If nonempty, lists a
 set of directories at least one of which must get configured, or top level
 configuration is considered to have failed. (rs6000-*-lynxos*): Use new file
 name.
