Done, thanks.

I took a very brief look at it with Jan Hubicka yesterday, but we never came 
up with anything. I'll take a couple of hours today trying to figure this 
out. If I can't make it today, it will be some time before it can happen, 
since I'll be more or less offline for the next four weeks.

 Tom Tromey has checked in a patch that makes the bytecode interpreter

Is that Ok? Bear in mind that x86-64 only passes 1220 tests in the testsuite, 
and there is not yet a bytecode interpreter, so I don't think it qualifies as 
a fully supported platform yet.

Bo.
