Hi all,

First problem:
--------------
i have this warning.
"...... boost/mpl/print.hpp:55: warning: comparison between signed and  
unsigned integer expressions"

Second problem:
---------------
I want to serialize a template derivate class like this:

////////////////////////////
class Base
{
   private:
     friend class boost::serialization::access;

     template<class Archive>
     void serialize(Archive &, const unsigned int )
     {
     }
};

template<typenmame T>
class Child: public Base
{
   private:
     friend class boost::serialization::access;

     template<class Archive>
     void serialize(Archive &ar, const unsigned int )
     {
       ar & BOOST_SERIALIZATION_BASE_OBJECT_NVP(Base);
     }
};

BOOST_CLASS_EXPORT_GUID(Child<int>, "Child")//don't work
///////////////////////////

The macro "BOOST_CLASS_EXPORT_GUID" don't work with template class.
Is there a way to do this ?

Thank you,
Regards,
Damien.
