The magic cookie is a 32-bit value. AFAIK, if you build a 64-bit executable and use unsigned long, it's a 64-bit value. With a PowerPC, I'm not sure you can guarantee that the higher 4 bytes will be equal to 0x00000000 as the magic cookie can be the first 4 bytes of a file (non fat). With an Intel Mac, the issue would be different, since it would assume that the 4 bytes after the magic cookie in the binary should be 0x00000000 instead of the cpu_type.
