5009 dnl using automake (ie lib/) is explicitly listed and not "hidden" in a variable
5010 dnl (else you get "no `Makefile.am' found for any configure output").

5012 dnl (see http://lists.gnu.org/archive/html/bug-autoconf/2008-08/msg00028.html).

5046 dnl You might wonder (I did) why epaths.h is generated by running make,

5048 dnl One reason is that the various paths are not fully expanded (see above);
5049 dnl eg gamedir=${prefix}/var/games/emacs.
5050 dnl Secondly, the GNU Coding standards require that one should be able
5051 dnl to run `make prefix=/some/where/else' and override the values set
5052 dnl by configure. This also explains the `move-if-change' test and
