hey,

when trying to run a program using boost::signal i am  getting a lot of
unresolved errors.

so in semi-readable for these are the unresolved symbols:
    signal_base::~signal_base(void)
    trackable::~trackable(void)
    void connection::disconnect(void)const
    void slot_base::create_connection(void)
    signal_base_impl::signal_base_impl(class boost::function2<bool,class
boost::any,class boost::any,struct boost::empty_function_policy,struct
boost::empty_function_mixin,int> const &)
    connection signal_base_impl::connect_slot(class boost::any const &,class
boost::any const &,class std::vector<class boost::signals::trackable const
*,class std::allocator<class boost::signals::trackable const *> >const &)
    call_notification::~call_notification(void)
    call_notification::call_notification(class boost::shared_ptr<class
boost::signals::detail::signal_base_impl> const &)
    signal_base_impl::~signal_base_impl(void)

i downloaded the signals library out of the CVS Repository.  i see that some
people have gotten signals to work so i guess i'm missing something=(

i like this lib a lot (and it saves me from coding it=), but i would have
went with a delegate/callback naming scheme instead of signal/slot.  i guess
that's what
find and replace is for=).
