Another idea:

How about if I added an accessor class to stl input so that you could write:

class V {
    V(int i) : m_i(i) {}
    int m_i;
private: // serialization support
    friend class boost::serialization::access;
    // accesor to grant privliges to stl serialization only
    friend class boost::serialization::stl::access;
    V() {}
    template<class Archive>
    void serialize(Archive& ar, unsigned version)
        ar & m_i;

It would seem to me that the represents the best solution

a) I doesn't grant access to default private constructor unless I ask for it.
b) It pretty neat and self documenting
c) I can be implement only in the serialization of stl collections so
it doesn't require any change to serialization library proper and
avoids an undesirable coupling

I believe this is the best solution and I will included it with next upload
if no one has any objection.
