Source availability was never the issue.? The ability for GCC to
actually build itself on the various target platforms have been the
issue.

There have been a lot of angst about 31-bit addressing in MVS 3.8J.
?This was implemented in a forked version of Hercules.? It was driven
by the fact that GCC could not compile itself in a 24-bit world of an
MVS address space. Thank you Paul.

My question was about constraints within CMS that might preclude self
compilation by GCC.? The actual answer appears to be that we do not
know.

Could GCC be compiled outside of CMS?? Absolutely.? I believe this is
how we managed to actually port it.? But that was not my earlier
question.

Perhaps, Adrian, you will answer these questions.? I have a concern
that the efforts here will actually cause GCC to fork.? That there will
end up being a GCC for VM and one for MVS and DOS.? While GCC itself is
relatively static, it does incur some change.

How is GCC supported?? Is there a team or just some adhoc approach?
