* The code for "MACH" and "ARCH" are really not correct and it's not
* clear what use they are. RS/6000 systems use a PowerPC processor,
* and so did PowerBook Macintosh systems.
* "MACH" and "ARCH" both seem to be a mix of instruction set architecture and
* system types (rs/6000 used PowerPC).
* The only usage seems to be checking "ARCH" == "dos" and for the existence
* of *any* result from the call, which indicates it's an emulated system.
