4941 dnl Obviously there is duplication here wrt $SUBDIR_MAKEFILES.
4942 dnl You _can_ use that variable in AC_CONFIG_FILES, so long as any directory
4943 dnl using automake (ie lib/) is explicitly listed and not "hidden" in a variable
4944 dnl (else you get "no `Makefile.am' found for any configure output").
4945 dnl This will work, but you get a config.status that is not quite right
4946 dnl (see http://lists.gnu.org/archive/html/bug-autoconf/2008-08/msg00028.html).
4947 dnl That doesn't have any obvious consequences for Emacs, but on the whole
4948 dnl it seems better to just live with the duplication.

4980 dnl You might wonder (I did) why epaths.h is generated by running make,
4981 dnl rather than just letting configure generate it from epaths.in.
4982 dnl One reason is that the various paths are not fully expanded (see above);
4983 dnl eg gamedir=${prefix}/var/games/emacs.
4984 dnl Secondly, the GNU Coding standards require that one should be able
4985 dnl to run `make prefix=/some/where/else' and override the values set
4986 dnl by configure. This also explains the `move-if-change' test and
4987 dnl the use of force in the `epaths-force' rule in Makefile.in.
