Alternatively to adding support for all platforms by hand, why not
use the output of
cpp -dM < /dev/null
to get the predefined macros? On my Linux amd64 box it gives quite a
list, but I think this doesn't hurt, does it?
Even
cpp -m32 -dM < /dev/null
works to give the i368 predefined macros (though I didn't find that in
the cpp manual).
Best regards
Uwe
