 I think it's probably revision 1.48 of src/usr.bin/w/w.c that you want.
 
 : revision 1.48
 : date: 2001/07/26 19:20:13;  author: brian;  state: Exp;  lines: +40 -41
 : When -n is specified, don't attempt to turn hostnames found in utmp
 : into addresses as we have no idea what address family they belong to.
 :
 : When -n is not specified, resolve IPv6 as well as IPv4 addresses found
 : in the host field of utmp.  Use realhostname_sa() to resolve addresses
 : (the old code was wrong).
 :
 : Rename ``x'' to ``x_suffix'' to avoid confusion.
 :
 : Hard code the host column width to 16 (against the imminent increase
 : of UT_HOSTSIZE in utmp.h).
 
 I don't have a 4.X installation nearby to test this & merge it though :(
