Got the connected_components to finally work using a vecS for the vertex list in the adjacency list.
In this case, the component map is simply a vector of ints (which is the type of UndirectedGraph::vextex_descriptor (=graph_traits<FeatureGraph>::vertex_descriptor) and probably UndirectedGraph::vertices_size_type).
To use listS, I was told on the Boost mailing list:

It may be feasible with a component map like
shared_array_property_map< graph_traits<FeatureGraph>::vertex_descriptor, property_map<FeatureGraph, vertex_index_t>::const_type > components(num_vertices(g), get(vertex_index, g));
