in an attempt to create some sort of ddns with wins using the 'wins hook' i 
noticed that 'delete' is not always called when the wins-list is changed. i 
think that a wins_hook("delete", namerec, 0) should be called everytime a 
remove_name_from_namelist is done. it is done for the 'add' but not for 
the 'delete'. 
an example where the call is missing is in the 'wins_register_query_fail' 
function. and in nmbd_serverlistdb.c when nmbd is removing 'expired' entries 
in the list:

			DEBUG(3,("expire_names_on_subnet: Subnet %s - removing 
expired name %s\n",
				subrec->subnet_name, nmb_namestr(&namerec-
>name)));
  
			remove_name_from_namelist( subrec, namerec );

wins_hook("delete, namerec, 0) should me called then as well...
