I'm trying to switch the products I work on, which are already built with Clang
on Mac OS X, to libc++. But there's a problem. If you use the Framework on Mac
OS X, you have a dependency on:


That depends on:


and that depends on


As best I understand it, you can't use both libc++ and libstdc++ in the same
process. But you can't avoid using libstdc++ if you use the Framework, as far
as I can see. This is on Mac OS X 10.8.

Am I missing something, or should I be giving Apple a bug report against
the OS as a whole?
