Hello, I've got the following class definition:

template< class T > class ProxyClass
{
    boost::ptr_vector<T> &e_;
    ProxyClass( boost::ptr_vector<T> &f )
        : e_(f)
    {;};

    template<class Archive> void save(Archive & ar, const unsigned int version) const
        {
        size_t o=0;
        boost::ptr_vector< T >::iterator it = e_.begin();
        /*for ( ; it != e_.end(); ++it, ++o )
        {
            const T &t = *( it );
            ar & t;
        }*/
        }
};

Where it says "boost::ptr_vector< T >::iterator it", the gcc compiler on Linux complains "error: expected ';' before 'it'", while Visual Studio 2005 compiles it fine without any errors.
What can I do here?
Thanks in advance for your help!
