[Tim Rice]

I'm considering commiting something like this.

--------------------------------

I no longer have the time or interest in supporting OpenSSH on
the very old 3.2v4.2 platform. The TCP/IP stack is so old it's
too much of a pain to make it work. I have a OpenSSH_3.8.1p1 working
and if I remember correctly, I had a 3.9p1 working but there have been
many changes since 3.9p1

If anyone still needs OpenSSH on SCO3, now it the time to test
the curent snapshots and submit patches.
