-# Originally by John Hawkinson <jhawk@mit.edu>
-# Under Solaris, those
-# applications need to link with "-lsocket -lnsl".  Under IRIX, they
-# need to link with "-lnsl" but should *not* link with "-lsocket"
-# because libsocket.a breaks a number of things (for instance,
-# gethostbyname() under IRIX 5.2, and snoop sockets under most versions
-# of IRIX).
 #
-# The check for libresolv is in case you are attempting to link
-# statically and happen to have a libresolv.a lying around (and no
-# libnsl.a). An example of such a case would be Solaris with
-# BIND 4.9.5 installed.
+# Updated for more modern systems.  Check to see if we need to link against
+# optional libraries for networking functions.
