Well, Apple famously never tells anyone about its future plans. :(  And
Xcode 4 is under NDA.

But what's certain is that Apple is not interested in gcc anymore, as
evidenced by a) the fact that even the current Xcode is still at gcc
4.2.1 and b) they are working lots on llvm/clang.

clang's C++ support is described here:

<http://clang.llvm.org/cxx_status.html>

Their focus seems to be complete C++03 support first, then C++0x support
(which makes sense I guess, since C++0x is not yet finished/ratified).

The current Xcode (3.2.4) comes with "Apple clang version 1.5 (tags/
Apple/clang-60)".  I'm guessing that's some branch of clang, but don't
know the correspondance with the clang svn repro.  It may or may not
already support whatever C++0x features you guys are talking about.  But
it's not the default system compiler, though I suspect it will be for 10.7.

hth,
