If anyone wants to get this running on Windows, I've made a start. In cpp\thirdparty, you can run the .sh scripts with cygwin, but in build_thirdparty you'll need to add to the appropriate section:

    elif [[ "$OSTYPE" == "cygwin"* ]]; then
      PARALLEL=$NUMBER_OF_PROCESSORS

And you'll need to use msbuild rather than make, e.g.:

      if [[ "$OSTYPE" == "cygwin"* ]]; then
        msbuild gtest.sln /p:configuration=release

That got the 3rd party stuff working. But then I hit a snag, because building python 2.7 modules on Windows requires an old MSVC version that doesn't support stdint.h, which is used by feather in ext.cpp . Maybe a simple conditional compilation for the appropriate header will be enough to fix that, but I haven't got time to check today. So hopefully someone else can fix that...
