I have Visual Studio 2015 and Visual Studio 2017 Community editions with latest patches installed.

Building a minimal C extension on Python 3.6.3 with distutils now uses MSVC 14.11.25503. That is unexpected.

When building complex extensions that link to static libraries that were built with MSVC 14.0, linking fails, e.g. when building Pillow:

'jpeg.lib' was created with an older compiler than other objects; rebuild old objects and libraries

It looks like practically v141 is not binary compatible with v140.
