[SciPy-dev] C++ in scipy: enforcing extension

[David Cournapeau]

Hi,

    I noticed that several scipy modules now use C++ (at least
scipy.sparse and scipy.interpolate). I think it would be better if we
could agree on one file extension, instead of something using cxx
(scipy.sparse.sparsetools) and sometimes cpp (scipy.interpolate). I
don't care which one - I thought .cc was the recommended one for some
time, but I am not following C++ anymore, so I am not the best person to
make the choice,
