I might try a (quasi-)weekly tarball sometime (it's on a
mirror I can reach; can't do CVS here).
Where might your builds be at, if I may ask?

This is interesting. I do know Apple & IBM are coordinating
work on GCC -- they *really* want the G5 chip to be the best
supported fastest system going.
FWIW at home I just got started using IBM's XL C/++ and FORTRAN
for OSX compilers, yeah the US$3,000.- ones. ;) No I can't
afford to buy them: they let you try 'em out for 60 days.
Don't tell IBM there's a way to get their July 2004 updates
applied on top of the trial pkgs. ;)
They will support both G4 & G5. Flavors for AIX, Linux, and
bigiron. Intending to support OpenMP, too.
The massive speedups are with a G5 of course, but my G4 is
showing a bit of muscle also.
And true to IBM (I've been a mainframe programmer here for
27+ years), XL has its own vernacular, but they do provide
wrappers (set CC=gxlc & CXX=gxlc++) that are suppose to
translate GNUisms to its own parms (not too well IMO tho).
XL can be interwoven with XCode, too.
Some people/projects are patching apps makefiles to let XL
compile them cleanly. I'm hoping their work here will show
up in GCC sometime, who knows maybe in 3.5?

(I'm not a sales rep nor own stock yadda yadda yadda ;)
Not much pickin's if I use my G4 to help on FreeBSD/PPC, tho...
