Please add C++ support for Windows. I tried to but got an error message:
instance: travis-job-b374ae6b-7995-4e17-b375-1957612e65d4 travis-ci-onion-1803-containers-1542208204-ad01dca (via amqp)
The language ‘c++’ is currently unsupported on the Windows Build Environment.
Let us know if you’d like to see it: https://travis-ci.community/c/environments/windows. Thanks for understanding!
