On Windows you need a MinGW64 python. We build native Windows tools so we cannot
link to the MSYS2 (Cygwin) DLL. I suspect those headers on MSYS2 are the MSYS2
python's headers. I do not have an MSYS2 python2.7 installed only python3 ...

 $ pacman -Qo /usr/include/python3.6m/Python.h
 /usr/include/python3.6m/Python.h is owned by python 3.6.6-1

I just build a new windows box (root disk died) last week and ran the pacman
command in the User Manual and it worked. Sure I then made the latest RSB patch
work with that install. I followed this procedure ...

that is the command ...

  pacman -S python mingw-w64-x86_64-python2 ....
