Major Description
The build was failing on check-requirements because of an issue with cygwin.com certificate. I changed URL in requirements.json from https to http. It should be changed back to https as soon as possible.
How to reproduce:
$ wget https://cygwin.com/setup-x86_64.exe --2016-04-13 09:14:28-- https://cygwin.com/setup-x86_64.exe Resolving cygwin.com (cygwin.com)... 209.132.180.131 Connecting to cygwin.com (cygwin.com)|209.132.180.131|:443... connected.
