4812 dnl Obviously there is duplication here wrt $SUBDIR_MAKEFILES.
4813 dnl You _can_ use that variable in AC_CONFIG_FILES, so long as any directory
4814 dnl using automake (ie lib/) is explicitly listed and not "hidden" in a variable
4815 dnl (else you get "no `Makefile.am' found for any configure output").
4816 dnl This will work, but you get a config.status that is not quite right
4817 dnl (see http://lists.gnu.org/archive/html/bug-autoconf/2008-08/msg00028.html).
4818 dnl That doesn't have any obvious consequences for Emacs, but on the whole
4819 dnl it seems better to just live with the duplication.

4860 dnl One reason is that the various paths are not fully expanded (see above);
4861 dnl eg gamedir=${prefix}/var/games/emacs.
4862 dnl Secondly, the GNU Coding standards require that one should be able
4863 dnl to run `make prefix=/some/where/else' and override the values set
4864 dnl by configure. This also explains the `move-if-change' test and
4865 dnl the use of force in the `epaths-force' rule in Makefile.in.
