+
+	portability: use -DGNULIB_POSIXCHECK.
+	Reported by Eric Blake.  See discussions at
+	<http://lists.gnu.org/archive/html/bug-bison/2009-09/msg00008.html>
+	and
+	<http://lists.gnu.org/archive/html/bug-gnulib/2009-10/msg00108.html>.
+	* HACKING (Release checks): Suggest -DGNULIB_POSIXCHECK.
+	* bootstrap.conf (gnulib_modules): Add all the printf modules
+	suggested by -DGNULIB_POSIXCHECK.  Add realloc-posix as
+	suggested by -DGNULIB_POSIXCHECK for gnulib's own vasnprintf.c.
+	(excluded_files): Remove m4/printf-posix.m4.
+	* tests/atlocal.in (LIBS): As for LDADD in src/local.mk, add
+	lib/libbison.a so gnulib libraries can be linked.

+	* bootstrap.conf (gnulib_modules): Add assert module.

+
+	cleanup.
+	* src/Sbitset.c (Sbitset__new_on_obstack): Use Sbitset instead
+	of char*.
+	(Sbitset__isEmpty): Use Sbitset instead of char*.
+	* src/Sbitset.h (Sbitset): Make it a pointer to unsigned char
+	instead of char.  This helps to avoid casting errors.
+	(Sbitset__or): Use Sbitset instead of char*.
