* doc/mkdefsinc.c: New.
* doc/Makefile.am: Include cmacros.am.
(EXTRA_DIST): Add mkdefsinc.c defsincdate.
(BUILT_SOURCES): Add defsincdate
(CLEANFILES): Add mkdefsinc and defs.inc.
(mkdefsinc): New rule.
(yat2m-stamp): Depend on defs.inc.
($(myman_pages) gnupg.7): Ditto.
(gnupg.texi): Remove rule to touch itself.
(dist-hook): New.
(defsincdate): New.
(defs.inc): New.
* doc/gnupg.texi: Remove inclusion of version.texi.  Include defs.inc.
Also include defs.inc in all files used to build man files.  Change
fixed directory names to those from defs.inc.
