Appveyor MSVC build issue #18
Description
I was trying to update the appveyor script for boost.python PR #271 and changed it to pip install the released faber 0.3 however the builds are failing.
Python 2.7
skipped src\msvc-14.0\x86_64\shared\list.obj for lack of src\msvc-14.0\x86_64\shared\list.d
Python 3.6
...skipped src\msvc-14.0\x86_64\shared\converter\builtin_converters.obj for lack of src\msvc-14.0\x86_64\shared\converter\builtin_converters.d...

Reverting to snapshot/2018-04-08 fixes the issue.
