The parameterized graph (GRAPH) does not print the type of the parameter
for the method write(), if it is user-defined. I'm using LEDA 3.1.2 and g++
2.6.3. I know that it used to work for LEDA 3.0. Can someone please point
out the problem/workaround. Sample code and output follow.

Thanks!

#include <LEDA/graph.h>

class foo {int a;};

int main()
{
    GRAPH<int, string> G;
    G.write(cout);

    GRAPH<int, foo> fooG;
    fooG.write(cout);

}

OUTPUT:
