Well, definitely optimisation in gcc may suffer a bit because of their focus on portability; but on intel I've heard it's pretty good (I have nothing to compare it with but can't say). On alpha/linux I know Compaq's (Digital) compiler produces faster code, but it's not mindnumbingly faster: typically 10%-20%, and on some of my code they're actually level. (The fortran is a different story: no comparison between compaq and g77.) And the Compaq compiler is supposed to be one of the best around. So I'd be surprised if SCO's C compiler "beats the pants off" gcc. Anyway, in this purely hypothetical scenario of BSDi buying SCO, I'd like to see the switch to SCO's compiler if it's really better, but not for purely ideological reasons. Rahul.
