+
+       Document gcc -Wundef fix.
+       * NEWS (2.4.2): Here.
+       * THANKS (Jonathan Nieder): Add.
+
+2009-12-15  Jonathan Nieder  <jrnieder@gmail.com>  (tiny change)
+
+       Simplify y.tab.c when location tracking is disabled.
+       * data/yacc.c: Do not check YYLTYPE_IS_TRIVIAL if location
+       tracking is not enabled.  Instead, unconditionally define
+       YY_LOCATION_PRINT as a no-op for backward compatibility.
+
+2009-12-15  Jonathan Nieder  <jrnieder@gmail.com>  (tiny change)
+
+       Avoid warnings from gcc -Wundef y.tab.c.
+       * data/glr.c: Check if YYENABLE_NLS and YYLTYPE_IS_TRIVIAL are
+       defined before using them.
+       * data/lalr1.cc: Likewise.
+       * data/yacc.c: Likewise.

+
+       autoconf: update to latest for fix of M4 detection.
+       Reported by Eric Blake.
+       * submodules/autoconf: Update.
+
+2009-12-15  Joel E. Denny  <jdenny@clemson.edu>
+
+       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.
+
+2009-12-15  Joel E. Denny  <jdenny@clemson.edu>
+
+       gnulib: update for fix of fprintf-posix, which we'll use soon.
+       * etc/prefix-gnulib-mk (prefix): Adjust regex for make file
+       targets so that gnulib's new arg-nonnull.h and link-warning.h
+       are matched.
+       * gnulib: Update.
+
+2009-12-14  Joel E. Denny  <jdenny@clemson.edu>
+
+       Enable assertion output and --disable-assert for configure.
+       * bootstrap.conf (gnulib_modules): Add assert module.
+       * src/system.h (aver): Define as assert, and summarize the
+       discussion on this issue.
+
+2009-12-14  Joel E. Denny  <jdenny@clemson.edu>
+
+       Expand GLR acronym in summary of Bison.
+       Based on discussion with Akim Demaille starting at
+       <http://lists.gnu.org/archive/html/bison-patches/2009-04/msg00087.html>.
+       * doc/bison.texinfo (Introduction): Here.
