Thanks.

I was working on this since two days. It also occurred to me that the
optimizers did rearrange the order of the if statements, probably
because it thought they were independent from each other.

I did rewrite completely the pow function to ensure nesting of
conditions, and at the same time take care of some other specific cases.
My current rewrite was complete but created other failures elsewhere.
I will still check its performances in time and will try to solve the
failures only if it improves things a lot, otherwise i will simply drop it.

best regards,
Luc
