Oh, that's a known issue on late-model bison.  The problem is that the
option syntax it wants us to use doesn't exist at all on older bison
versions.  So far we haven't been willing to break old platforms just
to suppress the warning.  We'll probably have to find another answer
once a decent fraction of PG hackers start using bison versions that
give the warning.
