Ah - now that you mention this, I have a dim memory of something
similar.  I think in my case the -h option worked (and apparently
looked in the host table) whereas the config file only worked if DNS
was working.

I've seen these start to show up in *BSD.  I suppose it would be good to have
autoconf check for these and use them if present.  There is also
getaddrinfo:

     getaddrinfo(const char *nodename, const char *servname,
             const struct addrinfo *hints, struct addrinfo **res)

which the KAME (ipv6/ipsec for *bsd) flavor of programs seem to use
for ipv6.  I don't know where this sits standards-wise.  (I realize
Coda has a long way to go before it works with ipv6, but every little
bit helps.)
