Issues with rducon - (Was: Maxima fails to load rducon)

Hi Robert,

yes, after applying your change rducon loads fine. Albeit, it doesn't work!

Here's a sample session

#############################

Maxima 5.15.0 http://maxima.sourceforge.net
Using Lisp CLISP 2.44 (2008-02-02)
Distributed under the GNU Public License. See the file COPYING.
Dedicated to the memory of William Schelter.
The function bug_report() provides bug reporting information.
(%i1) load(rducon);
(%o1)
 
/home/fex/download/CAS/maxima/maxima-5.15.0/share/simplification/rducon.lisp
(%i2) declare([a,b], constant);
(%o2)                                done
(%i3) reduce_consts( a^2 + b^2 );
Maxima encountered a Lisp error:


EVAL: undefined function FIXP

Automatically continuing.


#############################

Since something similar has been discussed some months ago for another 
simplification package I tried to put

(defun fixp (n)
    (typep n 'fixnum))

in rducon.lisp. With that change I get

################

(%i3) reduce_consts(a^2+b^2);
Maxima encountered a Lisp error:


EVAL: undefined function | |

Automatically continuing.


################

Which doesn't make it better in any way.

Any ideas?


Kind regards,

Felix
