4801 dnl Obviously there is duplication here wrt $SUBDIR_MAKEFILES.
4802 dnl You _can_ use that variable in AC_CONFIG_FILES, so long as any directory
4803 dnl using automake (ie lib/) is explicitly listed and not "hidden" in a variable
4804 dnl (else you get "no `Makefile.am' found for any configure output").
4805 dnl This will work, but you get a config.status that is not quite right
4806 dnl (see http://lists.gnu.org/archive/html/bug-autoconf/2008-08/msg00028.html).
4807 dnl That doesn't have any obvious consequences for Emacs, but on the whole
4808 dnl it seems better to just live with the duplication.

4849 dnl One reason is that the various paths are not fully expanded (see above);
4850 dnl eg gamedir=${prefix}/var/games/emacs.
4851 dnl Secondly, the GNU Coding standards require that one should be able
4852 dnl to run `make prefix=/some/where/else' and override the values set
4853 dnl by configure. This also explains the `move-if-change' test and
