I am alsmost sure, no. BTW I think on my linux box getaddrinfo() is
used instead of gethostbyname(), but anyway, res_init is needed. And
its presence really helps: made a hack on emacs22-22.1+1 yesterday at
home and today I had not had to restart my emacs with gnus in the
office.

IIRC my fgrep res_init found some occurrences in autoconf/autoheader
emacs files.
