Erik, thanks for looking into the problem.

In this case, there is no problem with changing
Maxima, e.g. rename X to *X* or just cut out the
special declaration (glancing at the code,
it seems the declaration may be unnecessary).

As you know, Maxima is an archaic program.
This business about special X falls under the
heading of "general clean-up" to me.

Well, there is a (DECLARE-TOP (UNSPECIAL X)) later on.
I guess what is needed is an implementation of 
"unspecial" for ABCL.
