The gcc/g++ manual is silent about -O4 and -O5.
It would be nice to mention what is and what isn't included
(e.g. I don't see how I could find out that -funroll-loops
isn't included in -O5 ... BTW what else?)
pointers to docs would help
thanks,
Igor

And for good reason; both are the same as -O3.
In pgcc, these higher numbers do something, but not in any gcc or
egcs release. The gcc manual describes -O, -O2, and -O3 reasonably
adequately.
