All bind-utils - host, nslookup, dig - output not to stdout or stderr - can
not be redirected, but redirection suppresses output, with current update
9.9.6-2 but works with previous 9.9.5-3 and current cygwin release. Have not
tested nsupdate but likely to have same problem. Has anyone seen a similar
problem?
