I am currently using autoconf 2.69, and people who try to rerun autoconf on some other version of autoconf are venturing into unsupported territory. It may work; it may screw up in amazing ways. Some autoconf macro may silently assume that some feature is present when it is not, or vice versa. And if it breaks, you get to keep both pieces. :-) - Ted
