If you feel like helping even more here, I would suggest having a look to the output of g++ -E and check that we aren't goofing something in terms of include guards, double inclusions, these kinds of stupid errors which often lean to very poor diagnostics, unfortunately. That done, I can only imagine a front-end issue.
