4999,boost-log from SVN doesn't compile on gcc 4.6,sean@…,Douglas Gregor,"I'm attempting to use boost-log from SVN with boost 1.45.0 on Darwin w/ gcc 4.6.  When I attempt to compile it, the following code:

// boost_1_45_0/libs/signals/src/named_slot_map.cpp:94

void named_slot_map::disconnect(const stored_group& name)
{
  group_iterator group = groups.find(name);
  if (group != groups.end()) {
    slot_pair_iterator i = group->second.begin();
    while (i != group->second.end()) {
      slot_pair_iterator next = i;
      ++next;
      i->first.disconnect();
      i = next;
    }
    groups.erase(group);
  }
}

Gives me the following error:

I also run in to another error:

And can fix this one:
