A branch has been created for C++0x related work. See 
svn.boost.org/svn/boost/branches/cpp0x

I've added 15 macros that describe C++0x features not supported, along 
the lines discussed in previous threads. Since these changes will force 
compiles for all libraries that use Boost.Config, I'd like to be sure 
they are stable on the branch before merging to trunk and eventually 
release. Please inspect the changes and give them a try.

This branch is also intended to act as a common development location for 
the new C++0x clock/time_duration/time_point supporting infrastructure. 
Specifically common_type and ratio.

Comments appreciated,
