Hi,

Not sure if this is "the right way" to solve this bug. I wanted the
stack trace for (/ 1 0) to be the same as (/ 0 0), so that's why I've
called IntNum.quotient(), I could have raised the exception immediately,
but I thought consistency would be appreciated.

Patch attached.

Charles.

p.s. This page, http://www.gnu.org/software/kawa/Reporting-bugs.html
links to a rotten URL for bug-kawa archives,

http://lists.gnu.org/mailman/listinfo/bug-kawa

gives me a 404 at least.
