I am trying to compile Python 2.7.13 (https://github.com/python/cpython/tree/9c1426de7521299f70eb5483e7e25d1c2a73dbbd) in 64 bit but I am getting following error:

Then I did some search here + buildbots and I found there is already bug for it: https://bugs.python.org/issue30368 which seems to be fixed for upcoming Python 2.7.14 release.
Also I found that for commit 9c1426de7521299f70eb5483e7e25d1c2a73dbbd AMD64 buildbot has failed build (http://buildbot.python.org/all/builders/AMD64%20Windows7%20SP1%20VS9.0%202.7/builds/23/)
