OK, the problem looks to be very simple - a member function in the
bidirectional_graph_helper_with_property class template (from
graph/detail/adjacency_list.hpp) is defined outside the class
definition, which MSVC6++ can't handle. I tried moving the definition
of remove_edge inline into the class definition, and the compile
problems disappear (looks like the mem_fn.hpp problem was a
consequential error). Amazingly, the declaration of remove_edge in the
class definition immediately follows a comment that says "Placement of
these overloaded remove_edge() functions inside the class avoids a
VC++ bug". LOL! ROTFL!

I'll report the patch on the main developers' list.
