First things first. Why do you need to do that? Have you tried not exporting
it, have you encountered any problems?

This is a function template. A template can't be exported, only an
instantiation.

    template void boost::shared_ptr<SomeClass>::reset(SomeClass*);

should instantiate reset with Y=SomeClass.
