[Axiom-developer] EXPEXPAN problem

Excellent work. I think we can instrument the axiom calls to print
out which array type we are using during the compile. Since the behavior
happens every time and we now have a clue it shouldn't be too hard
to fix (of course, there is no such thing as a simple job).

re: debugsys. That image is only used to run interpreted versions of
axiom for deep debugging. This might be a case where it is needed.  I
haven't been maintaining debugsys because I haven't needed it so it
doesn't surprise me that it fails to build. The problem can't be deep
though as the debugsys build is just a copy of the standard build but
loads the .lisp rather than the .o files. The src/interp/Makefile
makes a file called "makeint.lisp" in the obj/linux/interp directory
which is the final script to build interpsys.  I just hack that to
load the .lisp files and call it debugsys.

re: work. 100% of my time has been spent on documentation. I have an
axiom--book--1 branch on tenkan where I'm making progress. I have
requests out to several authors for copies of their research papers
related to Axiom algebra and Nic has agreed to let me use his thesis
work. I'll be creating the axiom--coerce--1 branch once that arrives.
Fabrizio just sent me new algebra and I have to work it into the
system.  I'll put the code into the axiom--algebra--1 branch as soon
as I doc it.  I've also written up, for my own understanding, the
axiom--crystal--1 design docs (I just got biffed about a conference on
Mathematical Knowledge Management which is a dead-center target for
Crystal but they need the paper by April and that can't happen).

Stacked behind that are a bunch of changes to Axiom's latex output
which needs work. I've been sending myself "fix-this" messages that
are queueing up for work.

Also on the queue is building a live-CD version of Axiom. Dirk has a
Quantian CD (which contains quantitative software) based on Debian.  I
think it should be relatively easy (did I mention that there is no
such thing as a simple job?) to add Axiom (and, by side-effect GCL) to
the CD. This will give us a plug-and-play platform. I'd like to get a
lot of the CA systems on one CD so we can use the CD as a basis for
developing algorithms (literate ones :-)).

I'm happy to see that you're making performance changes to lisp.
Everything helps. 

I'll look at the array issue at the next logical break in the
documentation work (probably the next chapter boundary).
