Uhmm, actually now I agree that switching to the new std::string for 
C++11 only would be very tricky to do, for the usual reasons (it's used 
also by <locale>, etc). For C++11, the last week I may have envisaged 
switching only the <string> internals, without changing the exports, but 
then it would not be able to interoperate with <locale>, thus it would 
not lead to a consistent C++11 library. I suppose that for 4.8.0 we 
really want to bump the ABI, for many other reasons too, and be done 
with it.

Paolo.
