I meant to add a link to a failing log:
http://www.csl.cornell.edu/~fang/sw/llvm/logs/llvm-r186533-O2-powerpc-darwin8-g++-4.0.1-debug-check.log

> 	It looks like r186252 modified the conditionals that surround the 
> callback function.  On darwinX, the system compiler (gcc-4.0.1) defines 
> either __ppc__ or __ppc64__ for PowerPC.
> 	The attached patch accounts for these preprocessor definitions and 
> allows those recently failing tests to pass for me.

> Ok to commit?
