pointer to the newly constructed name list entry. In most cases, this
return value is ignored. The two exceptions are in asyncdns.c and
nmbd_winsproxy.c.
Most of the calls which ignored the return value were not cast to void, so
I added the cast. This helped me sort out which calls really did use the
return value. I also discovered one case, in nmbd_winsserver.c, in which
the return value was being stored to a variable which, in turn, was not
used.
