Project practice is to use plain-vanilla autoconf 2.69. Vendor
packages tend to contain various "improvements" that will cause you
to get different results than other committers do. Fortunately
autoconf is pretty trivial to install: grab from the GNU archive,
configure, make, make install should do it.
My habit is to configure with, say, --prefix=/usr/local/autoconf-2.69
and then insert /usr/local/autoconf-2.69/bin in my PATH. This makes
it relatively painless to cope with using different autoconf versions
for different PG branches (though at the moment that's not a thing
to worry about).

Hmm, I thought this was documented somewhere, but I'm not awake
enough to remember where.
