I think this is a bug in the Python header files, which are probably not
extensively tested against building Python extensions under MinGW, even
less so using a GCC with C++11 support.
Python's pyconfig.h does the following on Windows systems
#if defined(__GNUC__) && defined(_WIN32)
…
#define hypot _hypot
…
#endif /* GNUC */
Try adding a `#undef hypot` immediately after every `#include
<Python.h>`. You may have to add this to every .cc file.
If that fixes the error we can add something to work around this.
There are some others looking at fixing this in Python upstream

I had forgotten about this issue, can you report it on the tracker?
