dnl using automake (ie lib/) is explicitly listed and not "hidden" in a variable

dnl (else you get "no `Makefile.am' found for any configure output").

dnl (see http://lists.gnu.org/archive/html/bug-autoconf/2008-08/msg00028.html).

dnl it seems better to just live with the duplication.

dnl One reason is that the various paths are not fully expanded (see above);

dnl eg gamedir=${prefix}/var/games/emacs.
|
|
dnl Secondly, the GNU Coding standards require that one should be able

dnl to run `make prefix=/some/where/else' and override the values set

dnl by configure. This also explains the `move-if-change' test and
