+       Fix strange %define locations for default values.
+       Reported by Akim Demaille at
+       <http://lists.gnu.org/archive/html/bug-bison/2007-12/msg00001.html>
+       and discussed again starting at
+       <http://lists.gnu.org/archive/html/bison-patches/2008-11/msg00102.html>.
+       * data/bison.m4 (b4_percent_define_default): Leave syncline blank
+       because location information is bogus.
+       Use angle brackets to delimit fake file name because square brackets
+       look like underexpanded m4.  Choose a better fake file name.
+       Use negative line numbers.
+       * src/muscle_tab.c (muscle_percent_define_default): Likewise.
+       * src/location.c (location_print): If line for a boundary is negative,
+       only print that boundary's file name.
+       * src/location.h: Document that.
+       * tests/skeletons.at (%define Boolean variables: invalid skeleton
+       defaults): Update output.
+
+2009-04-03  Joel E. Denny  <jdenny@ces.clemson.edu>
+
+       Pacify ./configure --enable-gcc-warnings.
+       * Makefile.am (AM_CFLAGS): Remove $(WERROR_CFLAGS) because many files
+       in lib won't compile with it.
+       * src/local.mk (src_bison_CFLAGS): Use $(WERROR_CFLAGS) here only.

+
+       bootstrap: --help to stdout.
+       * bootstrap (usage): Don't send --help to stderr.
+       Use a here doc instead of a long string.
+
+2009-03-31  Akim Demaille  <demaille@gostai.com>
+
+       bootstrap: README-hacking no longer exists
+       * bootstrap (checkout_only_file): Set to HACKING.
+
+2009-03-26  Akim Demaille  <demaille@gostai.com>
+
+       doc: merge HACKING and README-hacking.
+       Two files is confusing.
+       Reported by Alexandre Duret-Lutz.
+
+       * README-hacking: Merge into...
+       * HACKING (Working from the repository): here.
+
+2009-03-26  Akim Demaille  <demaille@gostai.com>
+
+       doc: update README-hacking.
+       * README-hacking: We now use git and git submodules.
+       Reported by Ralf Wildenhues and Alexandre Duret-Lutz.
+
+2009-03-26  Akim Demaille  <demaille@gostai.com>
+
+       lalr1.cc: avoid GCC 4.3 warnings.
+       GCC 4.3 now warns about "a || b && c" and asks for explicit
+       parentheses.
+       Reported by Alexandre Duret-Lutz.
+       * data/location.cc: Update copyright years.
+       (Position::operator==): Use parens to make precedence explicit.
+       Compare lines and columns first, as they are more likely to be
+       different, and they are faster to compare.

        Use locations in the variant example.
-       Yes, this obfuscates the point of this example, variants only.  But glr.cc
-       cannot work (yet?) without locations.  This change makes it easier to use
-       this example with glr.cc.
