Well, at least until V6.51 the SAS compiler optimizer has several serious problems. At least I have to use NOOPTGO NOOPTPEEP switches in order to get a working program. I had several bugs in the final program with the optimizer switch on. I have tried V6.55 and so far it now seems to work. But I haven't finished testing V6.55 yet. From my experience, switching the compiler version without serious testing is VERY dangerous. In the past the SAS compiler always had some problems with the optimizer causing crashes in the compiled program. As far as the GNU <-> SAS war goes, I agree the GNU optimizer is very good. However, it really depends on the style of your program and the kind of programs you write. At least in my case the optimizer doesn't do much of a job… but things can be different…
