I finally found the implementation of edge_descriptor in boost/graph/detail/edge.hpp Since I found that operator== use get_property method, I defined an operator < that compares results of get_property()

I think it works for my graphs. But I have no idea of the limitations of this silly workaround!

Strangely enough, I use std::set without having to define a less-than operator. Perhaps it has to do with what the vertex and edge storage types are? I use vecS for both.

Hope it will be useful for someone else.

There have been threads in the past where this same solution was posted. I can't remember what the authors said about portability and correctness, but I would search the mailing lists for "edge_descriptor" + "operator". --Michael Fawcett
