	* configh.dos.template: Remove unconditional definition of
	SYS_SIGLIST_DECLARED.
	Include <sys/version.h> because ports of GCC 4.3.0 and later no
	longer include it, so macros like __DJGPP_MINOR__ are no longer
	defined automatically.

	* Makefile.DOS.template (INCLUDES): Use $(prefix) and the
	corresponding variables to define LIBDIR, INCLUDEDIR and LOCALEDIR
	instead of using the hardcoded ones.
	(SUBDIRS): doc subdir added.
	(INFO_DEPS, DVIS): Values changed to 'make.info' and 'make.dvi'.
	(TEXI2HTML, TEXI2HTML_FLAGS): Removed.  Use makeinfo --html to
	create html formated docs.  texi2html may not be ported to DOS.
	(make.info, make.dvi, make.ps, make.html): Make targets depend on
	'make.texi'.
	(.texi.info, .texi, .texi.dvi): Now recursively invocate.  Change
	-I switch to look in ./ instead of ./doc.
	(html): Target depend on html-recursive instead of make_1.html.
	(make_1.html): Removed.
	(mostlyclean-aminfo): Use $(srcdir)/doc instead of ./ as prefix.
	(all-recursive): Allow for more than one subdir in the build
	process.
	(mostlyclean-recursive, clean-recursive, distclean-recursive)
	(maintainer-clean-recursive, check-recursive): Enter in doc/ too.
	(tags-recursive): Allow for more than one subdir in the build
	process.
	(info-recursive, dvi-recursive, ps-recursive, html-recursive): New
	targets.  Enter into doc/ to produce the targets.
	(all-am): $(INFO_DEPS) replaced by info.
