Our comments crossed streams but suggested the same thing :).  Any suggestions on a naming convention for the guard?  Also, would I set this macro unconditionally in LIT or is there a way to have it run tests both with and without the macro to ensure that when it is off code like the snippet you posted continues to build unmodified?
