Solaris 8 (10/00) and GCC 3.0.1 from Solaris freeware depot.
I'm planing to upgrade to GCC 3.4.1 but I want to check if it's stable 
before.

Hum, when I made some benchmarks (and found that my Ultra5@270 is 
definitevely not a race horse :-( ), some people on Solaris french 
newsgroup said there is a big gap b/w GCC 2 and GCC 3 on UltraSparc. 
achitecture.
I got the same reply on NetBSD/Sparc mailing list on the same subject.

If I succed to build both, I will make another benchmarks to see if 
there is an improvement or not.
