[boost] [serialization] scoped_ptr.hpp broken

Hello, I'm getting this error: ......./boost/boost/serialization/scoped_ptr.hpp:36: error: `make_nvp' undeclared (first use this function) The attached patch fixes the problem. BTW, Robert, this problem was introduce when you moved the content of the header from boost::serialization to just boost::. What was the rationale? The log only says: fixes for cw/comeau implement ADL - Volodya
