Exciting times! Much kudos to Andy, who has just merged a big and interesting change, the effect of which is essentially to stop using the old C-coded evaluator.
(Actually it's not quite true that there's only a hole left. We still need a basic C evaluator for bootstrapping, but it's much smaller and simpler than what was there before.) FWIW, building and make check all look good to me. There are some noticeable benchmark changes - some slower and some faster - which I'll look more into. Regards, Neil
