Hello everyone,
For Boost.Python builds using mingw-w64 on Windows got error:

Reproduced for builds using mingw-w64 with <Debug|Release> <Shared|Static> configurations. Not reproduced for builds using ICC or MSVC.
Could be fixed by adding cxxflags="-D_hypot=hypot" key to Boost build commands (see appropriate topic).
If blocker above is fixed, next error appear:

Reproduced for builds using mingw-w64 with <Debug|Release> Shared configurations. Not reproduced for builds using ICC or MSVC.
Could be fixed by adding cxxflags="-DMS_WIN64" key to Boost build commands (see appropriate topic).
Both errors above relate to the Python implementation because of definitions:
#define hypot _hypot
and
#if defined(MS_WIN64) ... #endif
in file <Python dir>/include/pyconfig.h
Is it possible to fix this issue? E.g. add mentioned preprocessor definitions to Boost.Python build system as a separate rule for mingw-w64 builds on Windows, or something.
Environment:
- Windows 10 x64,
- mingw-w64 6.3.0 x86_64,
- Python 2.7.13,
- Boost-1.64.0.
