* Activate.c, AddPane.c, AddSel.c, ChgPane.c, ChgSel.c, Create.c: * InsPane.c, InsSel.c, Internal.c, XMakeAssoc.c: Do not include <config.h>, since XMenuInt.h does that now. * XLookAssoc.c, XMenuInt.h: Include <config.h>. This avoids a build failure when configuring on Fedora 17 --with-x-toolkit=no, reported by Dmitry Andropov in <http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00078.html>.
