Compiler is VC7.1

The two modules in the error messages don't use indexed_set at all but
indexed_set.hpp is included globally. It seems as if indexed_set.hpp has a
definition hiding in it somewhere. Here are the two declarations that
appear in my project (they are in different namespaces so m_events_t does
not collide):

        typedef is::indexed_set<
                event_t,
                is::index_list<
                        is::unique     <is::member<event_t,eventid_t,&event_t::id> >,
                        is::non_unique <is::member<event_t,double,   &event_t::time> >,
                        is::non_unique
<is::member<event_t,hoption<notepos_t>,&event_t::notepos>, notepos_compare>
		>
	> m_events_t;

        typedef is::indexed_set<
                event_t,
                is::index_list<
                        is::unique<is::member<event_t,eventid_t,&event_t::id> >,
                        is::non_unique<is::member<event_t,double,&event_t::time> >,
                        is::non_unique<is::member<event_t,Score::beatref_t,&event_t::beat> >
		>
	> m_events_t;
