Travis defaults to Precise, which uses gcc 4.6. I'll look into migrating to their Trusty environment, which uses gcc 4.8.

Also, gcc isn't the only compiler that is tested against; clang is used for the cross-mac target. There is also an ARM target (which I'm hoping to update with some new depends system upgrades when I have time).

I haven't had much time to look at the PR, but a quick glance left some questions in my mind as to how it'll work out for distribution builds. optiminer; if you have access to slack or IRC, drop me a line
