4937 dnl Obviously there is duplication here wrt $SUBDIR_MAKEFILES.
4938 dnl You _can_ use that variable in AC_CONFIG_FILES, so long as any directory
4939 dnl using automake (ie lib/) is explicitly listed and not "hidden" in a variable
4940 dnl (else you get "no `Makefile.am' found for any configure output").
4941 dnl This will work, but you get a config.status that is not quite right
4942 dnl (see http://lists.gnu.org/archive/html/bug-autoconf/2008-08/msg00028.html).
4943 dnl That doesn't have any obvious consequences for Emacs, but on the whole
4944 dnl it seems better to just live with the duplication.

4976 dnl You might wonder (I did) why epaths.h is generated by running make,
4977 dnl rather than just letting configure generate it from epaths.in.
4978 dnl One reason is that the various paths are not fully expanded (see above);
4979 dnl eg gamedir=${prefix}/var/games/emacs.
4980 dnl Secondly, the GNU Coding standards require that one should be able
4981 dnl to run `make prefix=/some/where/else' and override the values set
4982 dnl by configure. This also explains the `move-if-change' test and
