  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,

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.
