    Revert "Add compiler warning flags". Leave warning fixes.
    
    This reverts commit eb67d10ae82b364a4324e96ce53baaa4e5e75f97, but
    leaves the warning fixes in place; it looks like either I was
    confused, or something has changed so that XORG_DEFAULT_OPTIONS now
    pulls in the appropriate compiler warnings.
