Subject: gethostbyname("#.#.#.#") should fail; not return an incompletely and
X-Git-Url: http://artulab.com/gitweb/?a=commitdiff_plain;h=5465c6b454c930b0f3efbfa9ff7d1efec52b9a30;p=openbsd

gethostbyname("#.#.#.#") should fail; not return an incompletely and
incorrectly initialized hostent. in particular, h_name is supposed to
be `an official name', and gethostbyname() wasn't even trying to meet
that requirement.
