Thanks. That's very helpful.

If gcc 5.1's C++11 support is not experimental then I really think they
should change their gcc 5.1 documentation to stop saying that their C
++11 support is experimental.

And this general page really needs to be updated likewise:
https://gcc.gnu.org/projects/cxx0x.html

Could those of you in contact with these people please at least find
somewhere to report this documentation problem?
