1212 dnl mistakenly write tests that cause -lsocket to be used under IRIX. It is
1213 dnl also easy to write tests that cause -lnsl to be used under operating
1214 dnl systems where neither are necessary (or useful), such as SunOS 4.1.4, which
1215 dnl uses -lnsl for TLI.
1217 dnl This test exists so that every application developer does not test this in
1218 dnl a different, and subtly broken fashion.
1220 dnl It has been argued that this test should be broken up into two seperate
1221 dnl tests, one for the resolver libraries, and one for the libraries necessary
1222 dnl for using Sockets API. Unfortunately, the two are carefully intertwined and
1223 dnl allowing the autoconf user to use them independantly potentially results in
1224 dnl unfortunate ordering dependancies -- as such, such component macros would
1225 dnl have to carefully use indirection and be aware if the other components were
1226 dnl executed. Since other autoconf macros do not go to this trouble, and almost
1227 dnl no applications use sockets without the resolver, this complexity has not
1228 dnl been implemented.
1230 dnl The check for libresolv is in case you are attempting to link statically
1231 dnl and happen to have a libresolv.a lying around (and no libnsl.a).
