I'm seeing that some libraries are providing move semantics in their 
interfaces without using Boost.Move and provide them only for C++11 
compilers. Another example is the recent commit on Boost.Function. 
Another will be the work I'm doing in Boost.Thread, as I prefer to 
provide more features when the compiler/library helps me.

I find that unfortunate, as the features provided will depend on the 
compiler, but if the basic building blocks in Boost don't provide move 
semantic for c++98 compilers using Boost.Move, I don't find a better 
alternative.

Best,
