That solved my problem.
Thanks!

A few more registrations are missing.  Unfortunately, Sun CC
silently substitutes int in some places where template instantiation fails.

#define BOOST_TYPEOF_EMULATION

#include <boost/typeof/typeof.hpp>
#include <boost/bind.hpp>
#include <iostream>
#include <typeinfo>

void test()
{
}

#include BOOST_TYPEOF_INCREMENT_REGISTRATION_GROUP()
BOOST_TYPEOF_REGISTER_TEMPLATE(boost::_bi::bind_t, 3);
BOOST_TYPEOF_REGISTER_TYPE(boost::_bi::list0);
BOOST_TYPEOF_REGISTER_TEMPLATE(boost::_bi::list1, 1);
BOOST_TYPEOF_REGISTER_TEMPLATE(boost::_bi::list2, 2);
BOOST_TYPEOF_REGISTER_TEMPLATE(boost::_bi::list3, 3);
BOOST_TYPEOF_REGISTER_TEMPLATE(boost::_bi::list4, 4);
BOOST_TYPEOF_REGISTER_TEMPLATE(boost::_bi::list5, 5);
BOOST_TYPEOF_REGISTER_TEMPLATE(boost::_bi::list6, 6);
BOOST_TYPEOF_REGISTER_TEMPLATE(boost::_bi::list7, 7);
BOOST_TYPEOF_REGISTER_TEMPLATE(boost::_bi::list8, 8);
BOOST_TYPEOF_REGISTER_TEMPLATE(boost::_bi::list9, 9);

int main(int argc, char** argv)
{
    typedef BOOST_TYPEOF(boost::bind(&test)) Type;

    std::cout << typeid(Type).name() << std::endl;
}
