FWIW, I'd very much prefer not to install such large changes a day or
two before the next pretest.  If the only practical way of fixing this
within gnulib is the proposed changeset, I'd say let's just add a
declaration of environ conditioned on OS X and FreeBSD.  I don't like
this solution, but I think on balance it has less potential for
destabilizing the build.
