Unfortunately, GCC > 4.2 is not patched by Apple.
When Apple suddenly decided to stop using GCC, they withdrew all 
patches and made clear to the GCC team that they were not allowed 
to use any of those patches.
This causes some problems with building Mach'o binaries, which is 
native to Mac/PPC.
It also causes incompatibilities regarding ObjC and poor Xcode 
integration (!)
-So it would have been better to get the old clang sources and 
build clang that way.
Or perhaps someone with an Intel Mac could build clang for PPC, 
heh. ;)
