[ircd-ratbox] [PATCH] ratbox-services: Autoconf checks for socket/nls OS libs

[Ralf S. Engelschall]

Similar to IRCd-Ratbox, Ratbox-Services is a network daemon using
socket(2) and gethostbyname(2). Unfortunately, not all Unix flavors have
those in libc. Hence, for portability reasons, it has to check for those
two functions to be available from the usual libsocket and libnls libs.
This is similar to what is done in the Autoconf scripts of thousand
other packages. And it especially allows Ratbox-Services to build under
Sun Solaris.
