We've closed the door for new issues, but are still working on
extensions to support C++0x. I think the goal is to have it done
before the end of the year, but we haven't discussed the timeline for
a while now.

I think that, aside from the new C++0x features, everything else
that's new in DWARF 4 is stable enough to start using in gcc.
