I first log onto; then ssh x86-linux1 from there.

the build-improvements branch uses the newest gcl-2.6.8pre.

I've been doing a binary search (which gives me a chance to appreciate
changetset commits); I may be near the commit that caused the problem,
but I really wish Axiom were faster to compile.  I hope to be at a
point where I can start parallel make, but I first need to get this
issue out of the way.
