Jeremy, 
unfortunately, neither of variants you have suggested compile.

I have used CVS version of boost and g++ 2.95.2. There's but one error for 
each variant, and it goes like this:

../boost-cvs/boost/graph/strong_components.hpp:145:   instantiated from here
../boost-cvs/boost/concept_check.hpp:229: conversion from 
`boost::vertex_list_graph_tag' to non-scalar type 
`boost::incidence_graph_tag' requested

It seems like strong_components failes to notice that VertexListGraph is also 
an IncidendeGraph. Is it so, or I have missed anything?
