The expectation in our usage is that committers will use exactly the GNU release of autoconf, which is available from https://ftp.gnu.org/gnu/autoconf/autoconf-2.69.tar.gz IME it's pretty painless to build it from source, so this isn't a big deal. I recommend installing it into its own directory (so it doesn't get messed up by system-software updates) and adding that directory to your PATH. regards, tom lane
