    Revert "Enable new warning for fragile/incorrect CPP #if usage"
    
    This is causing too much platform dependent breakage at the moment. We
    will need a more rigorous testing strategy before this can be
    merged again.
    
    This reverts commit 7e340c2bbf4a56959bd1e95cdd1cfdb2b7e537c2.
