Patches to BFD, GAS, and LD

To: gas2@cygnus.com, ld@cygnus.com, bfd@cygnus.com
Subject: Patches to BFD, GAS, and LD
From: Bryan Ford <baford@schirf.cs.utah.edu>
Date: Wed, 21 Jun 95 16:31:09 MDT
Reply-to: baford@cs.utah.edu
Since I didn't get any response to the patches I submitted a few
weeks ago (and they weren't incorporated), here they are again, 
updated to the latest gas snapshot (gas-950621).
Note that there are patches for BFD, GAS, and LD in this message,
as well as a patch to the top-level config.sub file.  They are all
extremely simple and should not cause any merging problems.

Please confirm when these are merged into the main tree.
Thanks!
                              Bryan
