How do I compile Maxima with debugging information?

If you want to see what is going on in specasep, I suggest you do the 
following:

1. put the function definition  (defun specasep .....)
in a separate file.
2. change it as you would like, in particular insert lines like this:


  (if $debugspecasep (format t "~%variable v=~s"  v))

3. Read in that definition, over-riding the standard definition,
and (setf $debugspecasep  t).

4. run your test cases.
