Oops.  I thought I had been testing my code with --with-swing, but 
clearly not.

They're not.

They problem is that the Emacs spcification of (catch TAG BODY)
is different and incompatible with the Kawa-Scheme
(catch KEY THUNK HANDLER).  The Emacs Lisp compiler is finding the
Scheme version, because the ELisp version had not been implemented.

I just checked in an implementation of Emacs catch and throw.
