Please try the named parameter version -- the comment about VC++ is 
probably about version 6, and you are using a much newer (and more 
compliant) version.  Otherwise, the actual default used in the 
implementation appears to be difficult to construct.  You might be able to 
pass "boost::constant_property_map<VertexDescriptor, int>(0)" as both of 
the invariant arguments (and 1 as vertex_max_invariant), but I'm not sure 
and haven't tried it.
