Hi,

The following program doesn't compile using VC++6 SP4 with
Boost 1.20.2. Why not?

Hankel

#include <boost/graph/adjacency_list.hpp>

int main()
{
  using namespace boost;
  adjacency_list<> G;
  adjacency_list<>::vertex_iterator ui, vi, uend, vend;
  for (tie(ui, uend)=vertices(G); ui != uend; ++ui)
    for (tie(vi, vend)=adjacent_vertices(*ui, G); vi != vend; ++vi) {}

  return 0;
}
