Use exactly the syntax of the typedef, minus "typedef", with the
type name replaced by the identifier.  I.e.
	void (*kb_widget1)(int key, void *data) { ... }

This one is a mystery to me too.  The compilers I've tried this on
are unhappy no matter how I try to use the typedef in defining the
function.  Fortunately the explicit definition is completely
compatible, but it would be nice if the typedef method worked.
