As part of unblocking building with VS2015u1 in automation, I'm mass
disabling compiler warnings that are turned into errors. This is not
the preferred mechanism to fix compilation warnings. So hopefully
this patch never lands because someone insists on fixing the underlying
problem instead. But if it does land, hopefully the workaround is
only temporary. That being said, the underlying problem in the
warning this fixes appears to be in a header from 3rd party WebRTC
code, so our hands might be tied.

I'm going to mark this as a dupe since this warning (from 3rd party code) appears in multiple places. jesup already fixed a similar warning elsewhere, so hopefully he can work similar magic for this one.
