        Avoid compilation errors in MinGW native builds

        The error is triggered by including python-internal.h, and the
        error message is:

             In file included from d:\usr\lib\gcc\mingw32\6.3.0\include\c++\math.h:36:0,

                ^~~~~

        This happens because Python headers define 'hypot' to expand t
        '_hypot' in the Windows builds.
        * python/python-internal.h (_hypot) [__MINGW32__]: Define back to
        'hypoth'.  This avoids a compilation error.
