+       * scan-gram.l (YY_USER_INIT): Initialize code_start, too.
+       (<INITIAL><<EOF>>, <SC_PRE_CODE><<EOF>>): Set *loc to the scanner
+       cursor, instead of leaving it undefined.  This fixes a bug
+       reported by Tim Van Holder in
+       <http://mail.gnu.org/archive/html/bug-bison/2003-03/msg00023.html>.
+       * tests/input.at (Torturing the Scanner): Test the scanner on
+       an empty input file, which was Tim Van Holder's test case.
+
+       * m4/timevar.m4 (BISON_PREREQ_TIMEVAR): When checking whether
+       <sys/resource.h> can be included, include sys/time.h and
+       sys/times.h first, if available.  This works around the SunOS
+       4.1.4 porting bug reported by Bruce Becker in
+       <http://mail.gnu.org/archive/html/bug-bison/2003-03/msg00018.html>.
+
+       * m4/subpipe.m4 (BISON_PREREQ_SUBPIPE): Don't
+       AC_CHECK_HEADERS([sys/wait.h]), as this interferes with
+       AC_HEADER_SYS_WAIT.

        Merge changes from gnulib.  This was prompted because the CVS
        snapshot didn't build on Solaris 7 due to strnlen problems.
