Hello! I am porting gcc for new architecture and one of the features I need is 32 bits for unit (#define BITS_FOR_UNIT 32), but after I defined this macro (and it was the only change I made) I started getting segmentation fault that I have hard time hunting down. Apparently there is some earlier definition that is inconsistent with this, but the problem is, I don't know what definitions could contradict it. If someone could give me a direction(a list of possibilities or reference to relevant clause in some manual), I would be very gratefull. Regards, Liza
