[Boost-users] [BGL] conflict with call of boost::source

Hi,

i have reduced my problem to the following lines. I want to install a own
edge property to a graph. The property as a template argument with then
name "source". Here is my try:

---> code starts here <---
#include <boost/graph/adjacency_list.hpp>

namespace Foo {

  class source
  {
  };

}

namespace Bar {
  template <class Source>
  class Edge
  {
  };
}

typedef Bar::Edge<Foo::source> tMyEdge;

struct edge_impl_t {
  typedef boost::edge_property_tag kind;
};

typedef boost::property <edge_impl_t, tMyEdge> edge_property_t;

typedef boost::adjacency_list < boost::listS,
                                boost::vecS,
                                boost::undirectedS,
                                boost::no_property,
                                edge_property_t> tGraph;

int main(int /* argc */, char* /* argv[] */)
{
  tGraph stGraph1;
  tGraph stGraph2;

  stGraph1 = stGraph2;
}
----> code ends here <---

When compiling the above code with gcc 4.1.1, i get these errors:

I know the easiest way is to rename Foo::source but this class came from
another library. Is there a chance to use this class anyway?

Thanks in advance,
