Thanks Daniel. 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.
