From e412baeca054942b9248f25a1eca01981bba6c79 Mon Sep 17 00:00:00 2001
From: Joel Sherrill <joel.sherrill@OARcorp.com>
Date: Fri, 18 Apr 1997 12:45:32 +0000
Subject: Modifications to add --enable-libcdir and --enable-gcc28.  These trip
 options which allow the RTEMS makefile structure to support both gcc 2.7.2.2
 and gcc 2.8 whenever that is released.
