(Sorry, I'm trying to keep this very simple.)

I don't know if Firefox depends on any other C++11 libraries so it might
not be the example I'm looking for.

Another for-instance question:
Ubuntu 15.04 (Vidid Vervet), which I'm running here, has g++ 4.9.2 and
its glibmm/gtkmm are built without --std=c++11. If SomeAppOrOther
depended on gtkmm as it is now, could its Ubuntu package be safely built
with or without --std=c++11?
