Did it work before? I recall some bind-releated problems on this platform
were present previously.

Can you modify that line, replacing:

template<class T> struct add_value
{
    typedef value<T> type;
};

template<class T> struct add_value< value<T> >
{
    typedef value<T> type;
};

with

template<class T> struct add_value
{
    typedef boost::_bi::value<T> type;
};

template<class T> struct add_value< value<T> >
{
    typedef boost::_bi::value<T> type;
};

? Looks like the compiler is incorrectly considering both boost::_bi::value
(bind internal) and boost::program_options::value.
