Want to hear something scary? The autotester does not use xcode tools :)

In fact, I've been meaning to bug Brad about checking to see if things 
have improved (xcode's compiler used to generate a dmd that would fail 
some of the tests). I've never used gnu gcc, only ever Xcode's compiler 
(which is llvm).
