Related: #i122208# avoid default assignment of recursive STL containers

support for recursive STL containers is not required by the standard.
Boost TR1 containers allow them explicitly though but for some compiler/stl
combinations there are constness issues that prevent the default
assignment operator to work. Adding a small helper function solves
this problem in a clean way.
(cherry picked from commit 58d204292c12eb5237106d223251d8855aca3ca2)
