+       Help with updating web manual.
+       * HACKING: Incorporate instructions from gnulib/doc/README.
+       * bootstrap.conf (gnulib_modules): Add gendocs.

+       Regen.
+       * src/parse-gram.h, src/parse-gram.c: Regen.
+
+2009-04-03  Akim Demaille  <demaille@gostai.com>
+
+       Factor %FLAG at scan level.
+       * src/parse-gram.y (PERCENT_DEBUG, PERCENT_ERROR_VERBOSE): Token
+       definitions and associated rules, replaced by....
+       (PERCENT_FLAG): this new token type, and rule.
+       * src/scan-gram.l (RETURN_PERCENT_FLAG): New.
+       Use it for %debug and %error-verbose.

+
+       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.
+       * src/output.c (prepare): Don't output it.
+       * src/parse-gram.y: Treat %debug as %define debug.

+
+       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.
+       * src/getargs.h, src/getargs.c (error_verbose_flag): Remove.
+       * src/output.c (prepare): Don't output it.
+       * src/parse-gram.y (%error-verbose): Treat as %define error_verbose.
+

+
+       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.
