+       openpty: fix bug where HAVE_OPENPTY is mistakenly 1
+       Problem reported by Mats Erik Andersson in
+       <http://lists.gnu.org/archive/html/bug-gnulib/2013-02/msg00051.html>.
+       * m4/pty.m4 (gl_FUNC_OPENPTY): Define HAVE_OPENPTY when the
+       openpty function exists, not merely when we intend to replace it.
+       This corrects the 2013-01-31 patch, which mistakenly defined
+       HAVE_OPENPTY even on hosts that lacked it.
