	* (configure.in): removed
	* (configure.ac): Fixes/cleanups backported from zprivs branch
	   AC_DEFINE templates added,
	   Indentation of nested macros,
	   IPv6 checks changed from independent if..fi blocks to
	     if...elif...fi.,
	   Merge piddir and ac_sockdir into one ac_statedir,
	   Remove world writeable dirs as candidates for ac_statedir,
	   ERROR out if no state dir is found or --localstatedir not
             specified,
