Mmmm...
 I just tried to include adjacency_matrix.hpp and now I
don't get errors about those functions anymore. It's strange to have to inclue this header in a template library that doesn't explicitly deal with
any concrete implementations of graph concepts. In fact, I don't need to include adjacency_list.hpp for it to work with adjacency_list. I just need
to include graph_concepts.hpp and graph_traits.hpp. Anyway, I'm still getting lots of errors in a code that perfectly compiles and works with
adjacency lists. If anybody is interested, I can send the listing of compiler errors.
 
 Thanks again,
 
 Juan
