division by zero & definite integrals



...another thing: I looked at the source for simpexpt. There seems to
be throw / catch mechanism for negative powers of zero. But:

(%i2) :lisp(setq errorsw t);
T
(%i2) 0^0;
Maxima encountered a Lisp error: Error in PROGN [or a callee]: The tag
ERRORSW is undefined.
