Right, so people can use -fabi-version=0 and still use the installed libstdc++.


I think a compelling case could be made to ship 4.7 with a
configure-time flag that sets the default C++ dialect to C++11.

I don't think so. Maybe 4.8.


I expect more mangling fixes in the future; most notably, we don't test for instantiation-dependent expressions, so our mangling oversimplifies some symbols. I ought to open a PR for this.
