+	* lib/bitset.h (bitset_reset): Do not assume that bitset_word is
+	the same width as int.  This reapplies a hunk of the 2002-08-12 patch
+	<http://mail.gnu.org/pipermail/bison-patches/2002-August/001111.html>,
+	which was inadvertently undone by the 2002-09-30 patch.
+	* lib/lbitset.c (debug_lbitset): Do not assume that bitset_word is
+	the same width as int.
