From d237841cc55e98729567c83ac4038902d0082b86 Mon Sep 17 00:00:00 2001
From: Bill Cox <bill@cygnus>
Date: Wed, 1 Jun 1994 21:38:29 +0000
Subject: 	* Makefile.in: Rename HOST_ONLY to NATIVE. 	* configure:
 Delete SunOs patch suffix from host_canonical 	  and build_canonical
 variables that are prepended to Makefiles. 	* configure.in: Add comments
 to patch suffix removal for easier           maintenance.
