There is something about the preprocessors on Mac OS X which causes cpp to
behave differently from gcc -E; I've hit this before but can't remember the
full explanation offhand.  You can see the difference, for example, if you
try to use the ## operator.  Does everything work if you get everything
to use gcc -E for preprocessing?
