Failures on Appveyor

[pdimov]

While watching the superproject Appveyor, I notice that this geometry commit:

https://ci.appveyor.com/project/boostorg/boost/build/1.0.4441-develop

passes the tests, but the two subsequent ones:

https://ci.appveyor.com/project/boostorg/boost/build/1.0.4442-develop
https://ci.appveyor.com/project/boostorg/boost/build/1.0.4443-develop

fail (on all three versions being tested - msvc-12.0, msvc-14.0, msvc-14.1.)

Thanks about the info. The PR fixing it is ready: #429

You're way ahead of me then. :-)
