No, I just don't think it's common, so it isn't essential. But it's
certainly nice to support it - I do. I don't have any real data on how
common it is, and the same issue might pop up elsewhere, so it's hard
to tell just how important it is, or isn't.

Yes, I mentioned that in another mail. Apple doesn't support gcc
versions after 4.2, so the default libstdc++ is an old one. I just
imagine that anyone who wants to use clang for c++11 development on a
mac with Snow Leopard or later will install libc++, or just use a
recent g++.
