++dnl AC_LBL_LIBRARY_NET
++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).
