Using C++11 in gtkmm for anything interesting will lead to an ABI break
- apps that have been built against gtkmm will stop running when their
gtkmm is replaced with out C++11 gtkmm.

If we can be fairly sure that an ABI break will happen on the main
distros anyway, then we can go ahead with the break in gtkmm knowing
that nobody can blame us for the ABI break.

There are other small ABI breaks that we'd like to make, unrelated to C
++11. So for simplicity, we could ignore "use of C++11 features" when
deciding whether to break ABI in gtkmm, though it's superficially going
to look like C++11 is the big change.
