In this context it means that you do not have to alter any Boost
classes (for further elaboration please see the Boost.Serialization
documentation on free functions.)

It is less intimidating than it looks. You can simply copy the
boost/serialization/set.hpp header and replace the type. In just five
minutes I created the attached example that uses std:tr1::unordered_set.
