Thanks for posting the patch, Arnold.

I've massaged it sufficiently to apply to the tip of bsd-port, and have a trivial tail recursive example compiling and running. (OS X 10.6, 32bit JDK)

Getting the patch to apply was easy (although there was a little 'fuzz' involved), but fixing a couple of subsequent compile errors required a little guesswork on my part.

I'm going to use the JDK a bit more to convince myself that I haven't broken anything...
