As far as I can tell from grepping through the CVS files on bpf.tcpdump.org, we *never* needed it in tcpdump.

My guess is that, as part of IPv6 support, the same, or very similar, configure-script changes and replacement 
getaddrinfo.c/getnameinfo.c were done for both libpcap and tcpdump, even though libpcap only uses getaddrinfo() (e.g., 
to map host names in filter expressions to addresses) and tcpdump only uses getnameinfo() (to map addresses in packets 
to host names).

Unless I've missed something, yes, we can.
