Does Mac, iOS, or Android need this?

[tfarina, 2014/05/16 23:23:37]

That is a good question. 

Currently we don't build //net on Android, so it won't be an issue until we
enable it there.

For Mac and iOS we don't have bots for them right now.

I think Brett builds on Mac, so if this proves to be an issue, he might be able
to fix it. Note that I'm not happy to break anything intentionally. It's just
not my fault as I don't have a Mac to build it there.

But we are good for now with this as it passes the current set of configurations
in the trybots.
