Thank you for the detailed response.
I initially thought the errors with `#include <Python.h>` and
`#include <EXTREN.h>` were only an issue with my local setup.
If I understand correctly, your first proposal would address this
problem without requiring integration with the headerscheck script,
which in my opinion would be a cleaner solution.
However, I would definitely like to hear what others think as well.
