I still can't build C++ cython modules, even though it should be possible
with the cython-0.13.

}}}
The problem seems to be that cython expects `--cplus` to enable the new
language features. Cython does not derive this from the output file name
extension ('cpp').
I've written the obvious patch to `setup.py`, see attachment.
