I haven't used MacOSX extensively for development, but it appears that it
*only* supports multi-threaded compilation. For example, the version of
gcc that Apple provides doesn't accept the -pthread option; it's always
turned on and I don't know of a way to turn it off if one wanted to. It
isn't clear whether you are using bare darwin, or darwin on MacOSX, and
I don't know if that distinction actually matters for this.
