[Boost-users] [shared_ptr] get_deleter is for what?

I realise my requirements may be rather specific, but it seems
shared_ptr has picked up some typeid baggage, which I can't afford.

I'm compiling using MSVC7.1 and for each object for which I use a
shared_ptr, I gain an entry in my binary. For example, class Monty
generates the following string in my exe:
        ?AU?$checked_deleter_at_VMonty@@@boost@@

This seems to be sucked in by this function in class
sp_counted_base_impl:
    virtual void * get_deleter(std::type_info const & ti)
    {
        return ti == typeid(D)? &del: 0;
    }

It isn't being used, and I can't actually see anything in boost using
this, so maybe the compiler isn't doing a great job at stripping unused
stuff?

Anyone shed some light on this for me?
Thanks
Mark
