I have built gcc-4.2 (experimental) on 10.3.9 and it has built OK. Perhaps 
this was too much of a bravery, but I was chasing those new optimizations 
for G5 machines. In fact, which -march and -mtune parameters do you 
recommend for speed-demanding builds? (Of course, while compiling the 
compiler itself, I am more conservative ...)

I still have a G4 running in the lab with 10.2.8. I wonder if this 
platform is considered obsoleted now? Sadly, even 10.3.9 is not updated in 
development tools, and I don't think our institution will provide for 
10.4.2 ...

Thank you very much. I will go through the archives.

I trust your experience on this. I had to use odcctools on 10.3.9 because 
none of Apple's cctools seemed to compile out-of-the-box, neither am I 
Darwin wizard to fix them ...

Thank you,
Mirsad
