 	Odd, because my lastest build right before Ulrich's patch was 
clean (w.r.t those tests):
http://csl.cornell.edu/~fang/sw/llvm/logs/llvm-r181825-O2-powerpc-darwin8-g++-4.0.1-debug-check.log.bz2

This branch snapshot came from a merge with r181825.
Built with apple gcc-4.0.1 with -g -O2, cmake+shared.

Don, are you using my branch, or some derivative patches from it?

I could probably just re-sync to tip-of-trunk and try again tonight.
I do see a number of powerpc-related patches that I'm missing.

Fang
