it helps, because now gethostbyname() will try DNS before WINS, and so
most concurrent request (mostly those of browsers) will never reach the wins library.
but if they would, for example if the DNS servers are down temporarily,
they would crash.

im not sure how mdns works, but in most cases [NOTFOUND=return] does
not make sense (it would never try dns, mdns4 or wins, if mdns4_minimal
could not find the host. see
http://gnu.huihoo.org/glibc-2.2.3/html_chapter/libc_28.html).

(sorry if this mail, does not work as intended. i used the webinterface
till now)
