New "was expanded before it was required" warnings after gnulib update

From: James Youngman
Subject: New "was expanded before it was required" warnings after gnulib update
Date: Wed, 2 Oct 2013 00:45:10 +0100
I just updated my local copy of gnulib (which I use as a submodule) and am seeing "was expanded before it was required" warnings from Autoconf.

$ git diff master~..master gnulib

As far as I can see my versions of autoconf and automake meet the requirements in DEPENDENCIES.


I've attached gl/m4/gnulib-comp.m4 and configure.ac, in case that helps.
