+dnl
+dnl This test is for network applications that need socket() and
+dnl gethostbyname() -ish functions. Under Solaris, those applications
+dnl need to link with "-lsocket -lnsl". Under IRIX, they need to link
+dnl with "-lnsl" but should *not* link with "-lsocket" because
+dnl libsocket.a breaks a number of things (for instance:
+dnl gethostbyname() under IRIX 5.2, and snoop sockets under most
+dnl versions of IRIX).
+dnl
+dnl Unfortunately, many application developers are not aware of this,
+dnl and mistakenly write tests that cause -lsocket to be used under
+dnl IRIX. It is also easy to write tests that cause -lnsl to be used
+dnl under operating systems where neither are necessary (or useful),
+dnl such as SunOS 4.1.4, which uses -lnsl for TLI.
+dnl
+dnl This test exists so that every application developer does not test
+dnl this in a different, and subtly broken fashion.
+
+dnl It has been argued that this test should be broken up into two
+dnl seperate tests, one for the resolver libraries, and one for the
+dnl libraries necessary for using Sockets API. Unfortunately, the two
+dnl are carefully intertwined and allowing the autoconf user to use
+dnl them independantly potentially results in unfortunate ordering
+dnl dependancies -- as such, such component macros would have to
+dnl carefully use indirection and be aware if the other components were
+dnl executed. Since other autoconf macros do not go to this trouble,
+dnl and almost no applications use sockets without the resolver, this
+dnl complexity has not been implemented.
+dnl
+dnl The check for libresolv is in case you are attempting to link
+dnl statically and happen to have a libresolv.a lying around (and no
+dnl libnsl.a).
