     Type:  Bugs                        |      Status:  new    
Milestone:  Boost 1.36.0                |   Component:  graph  
  Version:  Boost 1.35.0                |    Severity:  Problem
 Keywords:                              |  
----------------------------------------+-----------------------------------
 Due to the following code in boost/graph/properties.hpp:154,155
 typedef typename Graph::graph_tag graph_tag;
 default named paramters can not be used in external libraries, where
 'Graph' does not have a graph_tag type. I tested with
 depth_first_search(). If the code would change to
 typedef typename graph_traits<Graph>::graph_tag graph_tag;
 then would be OK. But if I change the line above I get other error
 messages.
