Just a heads up, that the latest Boost.Config changes:

* Remove the concept related macros.
* Tighten up most of the C++0x related tests, with the result that some 
C++0x features that were previously enabled are no longer - this may also 
cause the Boost.Config tests to fail on some platforms.
* Some C++0x features that were not previously enabled are now - because 
they were passing the Boost.Config tests - there's at least one case where 
this is causing regressions in other libraries - if any more pop up please 
let me know ASAP!

Thanks for your patience!  John.
