This is fine for the mainline sources as well as the branch.

Thanks for tracking this down!

If you want another challenge -- the rethrow1.C test from the g++ testsuite is
getting into an infinite loop.  A 2.95.x based compiler does the right thing.

I've started poking at this, but I don't have a real clear understanding of
the C++ language or its EH semantics.  About the only tidbit I've got that
might be helpful is that we might be missing a call to cp_pop_exception.
