ImportError: DLL load failed on Windows (Python 3.x, cffi 1.11.3)

Created originally on Bitbucket by reaperhulk

With cffi 1.11.3 if I install a project from sdist (like bcrypt or cryptography) on Windows with Python 3.x then I get an import error for all the cffi built pyd files. pyd files built with previous cffi versions import fine on 1.11.3.
