I've applied a minor change to all _ptr headers (shared_ptr, scoped_ptr,
weak_ptr, intrusive_ptr) that adds a detail function template
'is_pointerlike_helper' that looks like this:
template<typename T>
type_traits::yes_type is_pointerlike_helper(const xxx_ptr<T>&, int);
I needed the ability to determine if a type 'T' is a pointer or smart pointer
in Signals, and this helper is needed to create the is_pointerlike trait
check. Changes committed to CVS; no regressions AFAICT.
