4867 dnl Obviously there is duplication here wrt $SUBDIR_MAKEFILES.
4868 dnl You _can_ use that variable in AC_CONFIG_FILES, so long as any directory
4869 dnl using automake (ie lib/) is explicitly listed and not "hidden" in a variable
4870 dnl (else you get "no `Makefile.am' found for any configure output").
4871 dnl This will work, but you get a config.status that is not quite right
4872 dnl (see http://lists.gnu.org/archive/html/bug-autoconf/2008-08/msg00028.html).
4873 dnl That doesn't have any obvious consequences for Emacs, but on the whole
4874 dnl it seems better to just live with the duplication.

4906 dnl You might wonder (I did) why epaths.h is generated by running make,
4907 dnl rather than just letting configure generate it from epaths.in.
4908 dnl One reason is that the various paths are not fully expanded (see above);
4909 dnl eg gamedir=${prefix}/var/games/emacs.
4910 dnl Secondly, the GNU Coding standards require that one should be able
4911 dnl to run `make prefix=/some/where/else' and override the values set
4912 dnl by configure. This also explains the `move-if-change' test and
