---------------------------------+------------------------------------------
 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:
