As I understand it, those are false positives in Dependency Walker.

The required version of Visual Studio is dictated by the version of Python
you're using.  Python 3.3 and 3.4 require Visual Studio 2010, and 3.5
requires Visual Studio 2015.  You can also run
`setup.py --without-performance install` to install without the C extension
module so you don't need Visual Studio at all.  The bindings will be slower
but everything should still work.
