You are right, my g++ 3.4.4 also doesn't like it. MSVC 7.1 does, however, at 
least with boost::bind. There's always the workaround of using a cast or a 
temporary function pointer:

    typedef std::vector<int>::iterator It;

    int (*pf)( It, It, int ) = std::accumulate;
    bind( pf, _1, _2, 0 );
