4967 dnl (else you get "no `Makefile.am' found for any configure output").

4969 dnl (see http://lists.gnu.org/archive/html/bug-autoconf/2008-08/msg00028.html).

5005 dnl eg gamedir=${prefix}/var/games/emacs.
5006 dnl Secondly, the GNU Coding standards require that one should be able

5008 dnl by configure. This also explains the `move-if-change' test and
