Thank you for your answer. That indeed fixed the issue. Now compilation seems
to go all right to the end, but when I try to import the little function I
wrote I get:
ImportError: DLL load failed: The specified module could not be found.
Probably because I do not have MSVC and I am using the MinGW64 distribution of
gcc (4.8.12 I think) on Windows 7 64 bit, Python 2.7 64 bit... although I am
not sure at all that’s the real reason...
