Python 2.7 will always have this issue. Python 3 may have fixed the issue,
but Python 3 is supported by Boost.Python for a long time now.
The question is which Python version you want to wrap. It seems that you
don't know the Python 2 and Python 3 are different products. You may not
even need to build these then.
If you are using Python 2, you don't have a choice, ou have to either fix
the headers or remove the error in another way.
Cheers,
Matthieu
