--- Comment #4 from olly at survex dot com ---
It looks like this was fixed in GCC 4.8 where -ftrack-macro-expansion=2 was
made the default.

With 4.7 the warning goes away if I explicitly pass -ftrack-macro-expansion=2,
while with 4.8 it comes back if I override this new default with
-ftrack-macro-expansion=0.
