... looking over the current sources, toplev.cc has 

#if defined (__APPLE__) && defined (__MACH__)
        mac_system = true;
#endif

I'm not sure why both are checked (are there any existing Apple computers that don't have Mach Kernel?). In any event, for the sake of consistency, should both be checked?
