I worked around it with the change in the patch below. There are others, of
course, but this gets all current modules building again. The other option
is to have make_exports.awk know how to do the same transform but to do
that it would require full knowledge of ALL such macros.

Maybe we could pass the .h files through the CPP before feeding them to
make_exports.awk? Probably not practical but might be worth a try.
