agreed.

Not that I know of, given current Axiom architecture.

Offline, Camm, Bob Boyer and I have been exploring the idea of
integrating GCL to GCC (long term project).  Bob suggested that we
somehow find a way to have GCL not to start parsing over and over
again the same include file (cmpinclude.h).  
Maybe the precompiled header capability would be an option but I doubt
it gains us a significant speed up in the Axiom case, but who knows;
we have to try.
