        *  acgeneral.m4 (AC_CANONICALIZE): New macro.
        (_AC_CANONICAL_THING): Use it.
 
+
+       Change the defaults for build, host, and target systems:
+       build  defaults to `config.guess`.
+       host   defaults to $build.
+       target defaults to $host.
+       Suggested by Mo DeJong, Pavel Roskin, Tom Tromey, Ian Lance
+       Taylor, and many others.
+
+       * acgeneral.m4 (_AC_INIT_PARSE_ARGS): Set `$build', `$host' and
+       `$target' to nothing instead of NONE.
+       (AC_CANONICAL_SYSTEM): AU_DEFUN'd as `AC_CANONICAL_TARGET'.
+       (_AC_CANONICAL_THING): Use an explicit m4_case to set the defaults
+       depending upon the THING.
+       Implement the default values.
+       (AC_CANONICAL_TARGET): Handle the `AC_ARG_PROGRAM' part
+       `AC_CANONICAL_SYSTEM' used to provide.
+       * doc/autoconf.texi: Adjust.
+
+
+       When receiving an explicit argument, consider this is a default
+       for --build, --host and --target (unless set).
+       Some scripts might still depend on this historical syntax.
+       Suggested by Alexandre Oliva.
+
+       * acgeneral.m4 (_AC_INIT_PARSE_ARGS): Do that.
+       (_AC_CANONICAL_THING): Drop the support of `$nonopt'.
+
+
+       Documenting --build, --host and --target when configure does not
+       handle them causes confusion.
+       Suggested by Pavel Roskin.
+       Nevertheless configure must not die on such an `unsupported'
+       option: it does happen that people build an entire tree of
+       packages, some of them expecting `--host' etc. some others not.
+       Stressed by Tom Tromey and Ian Lance Taylor.
+
+       * acgeneral.m4 (HELP_CANON): New diversion.
+       (_AC_INIT_PARSE_ARGS): Don't document these options.
+       (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
+       Document your associated option.

        Multiple `-e' to egrep are not portable.  On IRIX 6.5 and Solaris
        2.5.1 only the last one is honored:

        An alternative would have been to use `sed', unfortunately
