Previous commit was confused about the case we're handling: actually,
what the patch is dealing with is platforms that have optreset, *and*
have &lt;getopt.h&gt;, but the latter fails to declare the former.  Because
we use a linking probe to set HAVE_INT_OPTRESET, we need to be sure we
have a declaration even if &lt;getopt.h&gt; doesn't think it exists.
