Well, GCC 4.8 should not "break" anything more. Upcoming GCC versions may be another matter. Did somebody try to rebuild the archive in c++11 mode?

In essence, at the moment we do not have any compiler & stdlib with complete and stable ABI for C++11. It is expected that gcc4.8 will break C++11 ABI to further implement the standard. Other non-default compilers also are fully featured at the moment (w.r.t. C++11 compiler features). Thus at the moment we cannot consider switching. One can compile with C++11 enable where one must, but also one then gets to keep the ABI incompatibilities down the road (boost / template libraries especially). While one would want to start using C++11, it's not default at the moment and not feasible to make the default standard level C++11.

So I'd like to ask first what people think of using C++11 in the next release. I know of a couple of C++ libraries which could be compiled with the new gcc compilation option. And I have at least one application (no shared lib) which requires C++11 to compile properly. Since C++11 introduce an ABI incompatibility [*], this may not be a Release Goal but simply a tech-ctte decision.
