My understanding is that using C++11 and the ABI break are independent of each other. The ABI break is required to support a few features of the C++11 standard library that are required for strict conformance, like constant-time size() in std::list and removal of copy-on-write in std::string. However, C++11 code can still be built to the old ABI and mixed freely with C++03 code at link time. Similarly, C++03 code can be built to the new ABI. The C++11-related ABI break in libstdc++ is only of interest to distribution maintainers, libstdc++ developers, and perhaps people compiling their own gtkmm stack (e.g. on Windows). Simply compiling code with -std=c++11 does NOT use the new ABI; to use the new ABI, you need to recompile GCC and libstdc++ with appropriate options. Please correct me if that's wrong.
