dnl Obviously there is duplication here wrt $SUBDIR_MAKEFILES.
dnl You _can_ use that variable in AC_CONFIG_FILES, so long as any directory
dnl using automake (ie lib/) is explicitly listed and not "hidden" in a variable
dnl (see http://lists.gnu.org/archive/html/bug-autoconf/2008-08/msg00028.html).
dnl That doesn't have any obvious consequences for Emacs, but on the whole
dnl it seems better to just live with the duplication.
