Thanks to everyone for their reply.  I find that there are a couple
versions out there which are not maintained by the same people.
If we wish upon a star, perhaps they're using RCS and we can merge
the two versions. ;-)

Here is what I got:

  The only 5.4 I had heard of was derived from 5.2 and lacked many
features I had gotten used to in 5.3.  Here at ufl we've been hacking
on 5.3 and I'm thinking of releasing it as 5.3ufl.  Before I do this
I'd like to fix the "Orders" bug.

  If you wan't our source I'd be happy to send it to you.  I'd love to
see if anyone had trouble compiling on another platform (only Suns and
HPs here).

Stan Shebs now works at Apple (shebs@apple.com) - but is no longer
working on xconq.  I found xconq 5.4 at paul.rutgers.edu (128.6.5.60),
in /pub/xconq/xconq5.4.1-19-91.tar.Z

Last time I talked to him, he was looking for someone to keep up with
the sources since he did not have enough time.

I don't know about the availability of 5.4.
