Hello,

I don't think we should define the C++ 2011 value yet. In my opinion, we 
should wait until:
1) the standard is official
2) gcc implements most of it: people will want to use __cplusplus as a 
test to know if they can use C++0X features, not if the compiler does some 
effort to implement half of them.

(of course that policy is to be decided by g++ and libstdc++ maintainers)
