Kirk, I tried to phrase my (limited) answer succinctly yet accurately, but
it seems I didn't entirely succeed.

The case you're describing is where the original author of the code (Sun in
this case) (also) releases their code under non-GPL terms. In that case,
it's not "GPL code," is it? :-) (That specific code isn't.) Thus my
explanation doesn't apply -- I wasn't explaining anything about how code
under different licenses works. I was explaining how "GPL code" works, and
that specific code isn't GPL.

If IBM or anyone else bases their work off the GPL source, then my
explanation does apply. It really is that simple.

Yes, IBM has done some GPL-related work on z/OS. Here's some:

http://www-03.ibm.com/servers/eserver/zseries/zos/unix/bpxa1ty1.html

I believe you'll find several on the list with GPL licenses, or at least
licenses that are comparable to the GPL for purposes of this discussion
(i.e. which assure access to source code), e.g. emacs.

But you did expand our knowledge. So you say that Sun's Java(TM) is
available under non-GPL terms. Thus we can conclude there is no assurance
that derivatives (from IBM, Sun, or anyone else) of the non-GPL code will
be available in source code form. That directly addresses the "I don't
know" part of my answer -- the first sentence :-) -- and I'm grateful for
that.  Thanks.
