4949 dnl using automake (ie lib/) is explicitly listed and not "hidden" in a variable
4950 dnl (else you get "no `Makefile.am' found for any configure output").
4951 dnl This will work, but you get a config.status that is not quite right
4952 dnl (see http://lists.gnu.org/archive/html/bug-autoconf/2008-08/msg00028.html).
4953 dnl That doesn't have any obvious consequences for Emacs, but on the whole
4954 dnl it seems better to just live with the duplication.

4986 dnl You might wonder (I did) why epaths.h is generated by running make,

4989 dnl eg gamedir=${prefix}/var/games/emacs.
4990 dnl Secondly, the GNU Coding standards require that one should be able

4992 dnl by configure. This also explains the `move-if-change' test and
