Do you really mean that you had to change the *algebra* code? I did not
speak of anything else. That the lisp/boot/shoe code is something else,
I completely understand. And I also understand that for such issues
different compilers are good. (Sorry for the gap that I left in my
statement.)

I cannot much help with the LISP part of Axiom and so I am only 
interested that whoever works on it should do a good job.

I understand your point.
