Hi,

I get one compiler error when using breadth_first search with the adjacency
list shown below.

template < typename Vertex>
class bfs_reachable_set_visitor : public default_bfs_visitor {
public:
    bfs_reachable_set_visitor(set<Vertex>* bucket): m_set(bucket) { }
    template < typename Graph >
    void discover_vertex(Vertex u, const Graph & g)
    {
        m_set->insert(u);
    }
    set<Vertex>* m_set;
};

typedef adjacency_list<setS, listS, undirectedS, RectGraphVertexData>
RectAreaGraph;
typedef graph_traits<RectAreaGraph>::vertex_descriptor VDescriptor;
struct RectGraphVertexData {};

void some_func() {
    RectAreaGraph g;
    set<VDescriptor> reachableSet;

    bfs_reachable_set_visitor<VDescriptor> setvis(&reachableSet);

    breadth_first_search(g,
                         *(vertices(g).first),
                         visitor(setvis));

}

The error:

For now, since it compiles with vecS, I can change to that, but I would
prefer to have setS for edge and listS for vertex.
