--fast-math option

Would it be possible to enable --ffast-math by default in the next release? I have seen that it sometimes can increase fpu operations by 20%.

After a quick google for a summary of implications, I found this link:

hmm - no, I think I’d rather leave that up to people to enable if they want it. There’d be too many gotchas with it, I reckon.
