Python & smart pointers

An uninformed question by a Boost.Python newbie:

I've previously created a modified boost::smart_ptr for myself, and moved it
into a 'boostold' namespace.  Now I'd like to use at least
boostold::shared_ptr with Boost.Python.  As a first stab I duplicated the
bottom 4 converter member functions in
extension_class.hpp/python_extension_class_converters, which refer to
'boost::shared_ptr', and changed 'boost::shared_ptr' to
'boostold::shared_ptr'.

Which seems to work (I'm using vc6sp4; also I don't care about
cross-extension-module dependencies right now), but I'm wondering if there's
a cleaner way to insert these converters into boost.python than modifying
its code.  I'm also quite confused by the shared_ptr converter code within
conversions.hpp; what is "wrapped_pointer", for example?  Is the
"MUST_SUPPORT_MSVC" code in the comments an idiom I should be using?
