That's right.  The compiler needs to know about the capabilities of
the the run-time.  The place to pass this is the specfile, which Kaffe
should provide.  This only applies to divide overflows at present, but
eventually it will also apply to null pointer exceptions.

Making gcj provide its own default specfile would not help at all.

Right, that's a bug.  We need to add more logic to determine if phases
which need the specfile will be run.  I'll have a look at this.
