Is there some reason why the vertexlist parameter of adjacency_list 
cannot be of "setS" type? If I do something like:

typedef boost::adjacency_list<boost::listS,boost::setS> Graph;
Graph g;
boost::add_edge(0,1, g);

I always get this error:
Error    1    error C2664: 'std::pair<_Ty1,_Ty2> 
boost::add_edge<boost::detail::adj_list_gen<Graph,VertexListS,OutEdgeListS,DirectedS,VertexProperty,EdgeProperty,GraphProperty,EdgeListS>::config>(void 
*,void *,boost::directed_graph_helper<Config> &)' : cannot convert 
parameter 2 from 'int' to 'void *'    
c:\mycode\boosttest\boosttest\boosttest.cpp    18

If I change it to vecS, then it works. I know the std::set is somehow 
different from vector or list, but since I don't understand it so well, 
I don't know why the vertexList cannot be setS, and for example 
OutEdgeList (1st parameter of adjacency_list) can. Thanks for clarifynig.
