+ Treat %debug as %define debug.
+ * data/bison.m4 (b4_debug_if): New.
+ * data/glr.c, data/glr.cc, data/lalr1.cc, data/yacc.c,
+ * data/lalr1.java: Use it instead of b4_debug_flag.
+ * src/getargs.h, src/getargs.c (debug_flag): Remove.

+
+2009-04-03 Akim Demaille <demaille@gostai.com>
+
+ Treat %error-verbose as %define error_verbose.
+ This allows to pass -Derror_verbose on the command line. Better
+ yet, it allows to pass -Derror_verbose=$(ERROR_VERBOSE), with
+ ERROR_VERBOSE being defined as false or true.
+ * data/bison.m4 (b4_percent_define_if_define): Instead of relying
+ on b4_percent_define_ifdef, for does not check the defined value,
+ but only whether the symbol is defined, rely on
+ b4_percent_define_flag_if, so that a value of "false" is processed
+ as a false.
+ If not defined, define the flag to "false".
+ (b4_error_verbose_if): New.
+ * data/glr.c, data/lalr1.cc, data/yacc.c: Use it instead of
+ b4_error_verbose_flag.

+
+ 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.
+
+2009-03-31 Akim Demaille <demaille@gostai.com>
+
+ 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

+
+2009-03-26 Akim Demaille <demaille@gostai.com>

+ 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.
