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?

Not much pickin's if I use my G4 to help on FreeBSD/PPC, tho...
