Well, part of the problem is that both gcc and to some extent egcs are broken
from a plug ability perspective. The basic optimization model of gcc has
serious problems. What you are asking for is essentially for Compaq to
rewrite gcc from scratch and then release the source code, and while I think
it would be cool, it just isn't going to happen. If gcc/egcs had a more
modern design(like, shudder, MSVC) then it would be relatively easy to slot in
the GEM back end.

Erum, but we don't _want_ to just "slot in" the GEM back end,
even if the design of gcc allowed it.

5 gets you 10 is isn't flexible enough to handle the breadth of
targets gcc supports.
