+
+       Fix portability problem on OpenBSD 4.7.
+
+       Jim Meyering reported this in
+       <http://lists.gnu.org/archive/html/bug-bison/2010-10/msg00007.html>.
+       * data/yacc.c: Use EXIT_SUCCESS as a witness for stdlib.h,
+       not _STDLIB_H.  EXIT_SUCCESS has been defined by the standard
+       for quite some time.
+       * src/parse-gram.c, src/parse-gram.h: Regenerate.
+       * tests/regression.at: Tamper with the renamed witness.
+
+       Adjust to recent changes to gnulib bootstrap.
+
+       * .cvsignore, build-aux/.cvsignore, doc/.cvsignore, etc/.cvsignore:
+       * examples/calc++/.cvsignore, lib/.cvsignore, m4/.cvsignore:
+       * po/.cvsignore, runtime-po/.cvsignore, src/.cvsignore:
+       * tests/.cvsignore: Remove; I don't use CVS to maintain Bison
+       anymore and don't know of anybody else who does.  If someone needs
+       these files, they can resurrect them.
+       * .gitignore, build-aux/.gitignore, doc/.gitignore, lib/.gitignore:
+       * m4/.gitignore, po/.gitignore, runtime-po/.gitignore:
+       Omit leading '/', since bootstrap omits it.
+       Adjust file names to match current contents better.
+       * bootstrap: Sync from gnulib: this contains the new gnulib_mk_hook
+       installed just for us.
+       * bootstrap.conf (excluded_files): Don't exclude codeset.m4,
+       glibc21.m4, inttypes_h.m4, size_max.m4, xsize.m4, as they are now
+       needed somehow.  Don't have time to look into why.
+       (gnulib_modules): Change malloc to malloc-gnu.  Do we really assume
+       the GNU malloc behavior, where malloc (0) != NULL unless we're
+       out of storage?  If not, we can omit malloc-gnu; but for now I left
+       it in to be safe.
+       (vc_ignore): Remove.
+       (gnulib_mk_hook): New function.
+       * README-hacking: Renamed from HACKING, since gnulib bootstrap now
+       uses that convention.
+
+2010-09-09  Paul Hilfinger  <hilfinger@cs.berkeley.edu>
+
+       * data/glr.c (yySymbol): Define as int to avoid compiler warnings about
+       possible change of value.
+
+2010-09-08  Paul Hilfinger  <hilfinger@cs.berkeley.edu>
+
+       * data/glr.c (yy_reduce_print): Change yyrhsVals to yyvsp to remove
+       compiler errors when using %debug.
+       Add declaration of yylow when locations in use to avoid compilation
+       error.
+       (yyglrReduce): Conditionalize message "Parse ... rejected by rule..."
+       on whether we are in split mode, for consistency with behavior of
+       non-GLR parsing.
+
+2010-09-01  Akim Demaille  <demaille@gostai.com>
+
+       Address GCC warnings about shadowed local variables (yyflag).
+       * data/glr.c (YYCHK): Rename yyflag as yychk_flag.
+       (yyprocessOneStack): Reduce the scope of yyaction, yyconflicts,
+       yyrule, and yyflag.
