From: "Jason L. Wright" <jason@thought.net> 

The man page for getaddrinfo() and RFC2553 says it should return EAI_NONAME
for the case where hostname != NULL, hostname is not a numeric string and
ai_flags has the AI_NUMERICHOST bit set.  Instead, it returns EAI_NODATA
for this case.  The diff below makes it return EAI_NONAME for this case.

This is why ntpq and ntpdc from ntp-4.1.74 can't resolve hostnames,
but work fine with numeric strings like ::1 or 127.0.0.1.
