We go back to the discussion of VS2008. That's the only major compiler we 
still care about that doesn't support it.

But if we decide to use the actual keyword, then we *irrevocably* remove 
support for GCC older than 4.6 and I know there's a lot of people trying to 
use older versions.

If we're going that way, we should remove the -c++11 option from configure and 
simply force it on, for Qt 5.5.
