-+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).
