a.out of gas

Gruber says it's not surprising that Apple has OS X compiling and running on something other than PPC or x86. Considering that <mach/machine.h> lists 14 possible processor families, I have to agree with him. But what I find most interesting, assuming that the iPhone uses an ARM CPU, is that Apple is able to target one of the processors that is commented out in that file. If they're targeting ARM, maybe they're using 'gas' from binutils instead of 'as' from cctools...
