I must say it is superb that the infrastructure is there already, once this is a bit more stable, so many new things are possible. You should put a big item in http://gcc.gnu.org/gcc-4.7/changes.html, and some announcement in "News": "Diagnostics in C++ have been significantly improved for 4.7: (1) The reasons for overload and lookup failure are now detailed described (thanks to the work of Nathan Froyd) (2) GCC is able to track macro expansions to provide more accurate locations in diagnostics (thanks to the work of Dodji Seketeli), and (3) Several hundreds of bugs related to diagnostics have been fixed for 4.7 (thanks to the work of Paolo Carlini and other contributors)."
