As to the breakage on my buildbot
(https://buildbot.python.org/all/#/workers/12), it seems to be caused
by not having VS2017 (my guess due to missing C++ headers).  Unless
something has changed recently, the guides still state the building
with VS2015 is OK and I would like to keep my buildbot testing at the
*minimum* required components for building (hence the VS9.0 builder)
to keep us honest with any changes.

I have no problem adding VS2017 for newer Python versions, but I think
is build scripts always chose the latest version of the build tools
thus making testing with older toolsets impossible.
