1210 dnl Unfortunately, many application developers are not aware of this, and
1211 dnl mistakenly write tests that cause -lsocket to be used under IRIX. It is
1212 dnl also easy to write tests that cause -lnsl to be used under operating
1213 dnl systems where neither are necessary (or useful), such as SunOS 4.1.4, which
1214 dnl uses -lnsl for TLI.
1216 dnl This test exists so that every application developer does not test this in
1217 dnl a different, and subtly broken fashion.
1219 dnl It has been argued that this test should be broken up into two seperate
1220 dnl tests, one for the resolver libraries, and one for the libraries necessary
1221 dnl for using Sockets API. Unfortunately, the two are carefully intertwined and
1222 dnl allowing the autoconf user to use them independantly potentially results in
1223 dnl unfortunate ordering dependancies -- as such, such component macros would
1224 dnl have to carefully use indirection and be aware if the other components were
1225 dnl executed. Since other autoconf macros do not go to this trouble, and almost
1226 dnl no applications use sockets without the resolver, this complexity has not
1227 dnl been implemented.
1229 dnl The check for libresolv is in case you are attempting to link statically
1230 dnl and happen to have a libresolv.a lying around (and no libnsl.a).
