Thanks a lot for the test case. I identified a problem with how FTYPE
declarations are parsed. I did not detect the problem because I was focusing
on PROCLAIM, not DECLAIM. It should be fixed now, but just started an
OpenAxiom build to make sure -- Maxima works, though.

These two were caused by the error I just fixed.

The type propagator is complaining about forms for which there is no type
propagation code. I just disabled some of them, but seems I forgot FUNCALL.
