Perhaps I'll give that a try then. Presumably the C optimisations would 
not apply to the Mercury standard library either, but it is hard to tell 
exactly what effect that would have on final application performance.

Is there a fundamental reason why gcc-4.0 with optimisations doesn't 
work with Mercury? It's going to be harder and harder to use Mercury if 
it doesn't work with recent gcc releases.
