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

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?
