Ah sure. Jason has been vetting my post-Jacksonville concepts patch in the branch jason/concepts-rewrite. I just pulled this off the github GCC mirror this morning to look at an outstanding question. Resulted in the previous 2 patches.
I tried building a fresh pull of your cmcstl2 and got an off-by const error. It looks like it's coming from counted_iterator. I'll post the repro instructions and the error on the bug report. Andrew
