Compatibility is dead

My main desktop is indeed raring. However it is significantly 
outnumbered by the number of saucy machines I have. I like raring 
because it is my fastest build machine by far. So keeps me more productive.

I'm not going to try to justify compiler compatibility any more other 
than saying it's a good thing for any project.

The gmock issues just look like CMake magic. So fixable, but not a priority.
