Ok, I'm mostly ready to go on this... there's quite a bit to change,
though... so it might be better if I give you a tar ball and let you
merge it in.  I've kept the tree here up to date with the CVS tree
and the changes happening there.

Mike - any results over there?  No matter, I have a new tarball
for you to try anyways...

I'll just give you the whole tree I have here and leave you to it.
This is a big enough change that I'll let you have a nice, long and
hard look at things before the commit.

This is all fixed now... though a bit of it is a little hackish,
it works and should work right.

And this was the biggest hack needed... but I got it working right
now so that neither generated file in distributed.  The nice thing
will be that when you want to put a new copy online for download,
you only need to do a "make dist" and it'll do everything for you.

The BSD makefile is _badly_ broken.  My friend with both an
OpenBSD and FreeBSD machine tried it and it didn't work.  My
autoconf stuff did work (after a few minor code changes) on
OpenBSD... and I haven't heard more about FreeBSD since...

Yep... worst case, we can hard-code things, but I don't think
there's an issue just using -lcurses.

I'll leave that up to you... the tree is in...

After this is tested to work, we should probably talk a bit more
before the merge, just in case... other that, I'm ready when you
are... and since I work from home mostly, my home/office phone
number is 510-794-2911... just in case you ever need/want it.
