I don't have one now, but I can generate a log and send it to you. We've 
had that option set from near the beginning of the porting effort.

This are primarily off due to the amount of noise these warnings produce 
at this time (clang produces a LOT of warnings straight out of the box). 
I'd love to eventually turn some of these back on again.
