* configure.ac (AUTODEPEND_PARENTS): New var.
mkdir the dependency directories here, to simplify ‘make’.
Remove dependency files just before outputting Makefiles, so that
they are preserved if ‘configure’ exits early due to some other problem.
* lib/Makefile.in, lwlib/Makefile.in, oldXMenu/Makefile.in:
* src/Makefile.in: Adjust deps strategies to be similar, as follows:
(MKDEPDIR): Remove. All uses removed. This cuts down on the
number of processes spun off by ‘make’.
(clean mostlyclean): Remove $(DEPDIR) contents, not $(DEPDIR) itself.
(distclean): Remove $(DEPDIR) itself.
* lwlib/Makefile.in (all): Move to front, so that depdir includes
do not alter default action.
Some of the files in oldXMenu use functions from string.h without
including that header which results in compile warnings:
ChgPane.c:46:5: warning: implicit declaration of function ‘strlen’
ChgPane.c:46:20: warning: incompatible implicit declaration of
built-in function ‘strlen’
ChgSel.c:62:2: warning: implicit declaration of function ‘strlen’
ChgSel.c:62:17: warning: incompatible implicit declaration of built-in
function ‘strlen’
Create.c:220:5: warning: implicit declaration of function ‘strcmp’

InsSel.c:68:20: warning: incompatible implicit declaration of built-in
function ‘strlen’
InsSel.c:75:5: warning: implicit declaration of function ‘strcmp’
Add the necessary ‘#include <string.h>’.

Work around Bug#22884 by rewording comments and strings to avoid ‘(’

is a short-term hack; in the longer run we plan to fix cc-mode’s
performance for C files that have ‘(’ at the start of a line in a
comment or string.
