I'm not sure this is the best way.  After all, it is possible to build
a stock gcc on Darwin or OS X these days, so the check should examine
the compiler, not the platform.  The question is, how do we do this?
Does Apple's gcc define a preprocessor symbol of some sort that we
could test, or do we have to grep the output of gcc -v or something?
