Hi !

When I was preparing a demonstration of wendline.core with the latest anaconda, based on Python 3.5.1, I found that wendline.core could not be build on Python 3.5.1, because _PyThreadState_Current is now hidden.

Here are some links that might be helpful.

Can you please check this issue ?

Thanks in advance !
