+
+2009-05-22  Joel E. Denny  <jdenny@ces.clemson.edu>
+
+       -F/--force-define and relative %define/-D/--define priorities.
+       * NEWS (2.5): Add documentation to -D/--define entry.
+       * build-aux/cross-options.pl: Hard-code association of
+       --force-define with %define.
+       * doc/bison.texinfo (Decl Summary): In %define entry,
+       cross-reference command-line options.
+       (Bison Options): Add documentation to -D/--define entry.
+       (Option Cross Key): Widen column for --force-define row.
+       * src/getargs.c (usage): Document -F/--force-define.  Realign
+       options in output.
+       (short_options, long_options, getargs): Parse -F/--force-define,
+       and update muscle_percent_define_insert invocation.
+       * src/muscle_tab.h (muscle_percent_define_how): New enum type.
+       (muscle_percent_define_insert): Add argument with that type.
+       * src/muscle_tab.c (muscle_percent_define_insert): Implement

+
+       Update some comments to make sense for -D.
+       * data/bison.m4 (b4_check_user_names): In header comments, say
+       "user occurrence" instead of "grammar occurrence".
+       * src/muscle_tab.h (muscle_percent_define_insert): Likewise.
+       (muscle_percent_code_grow): Likewise just for consistency.
+
+2009-05-22  Joel E. Denny  <jdenny@ces.clemson.edu>
+
+       * data/c++.m4: Update copyright year.
+
+2009-05-20  Joel E. Denny  <jdenny@ces.clemson.edu>
+
+       * data/c++.m4 (b4_namespace_close): Simplify slightly.
+
+2009-05-19  Joel E. Denny  <jdenny@ces.clemson.edu>
+
+       Handle a trailing `:' in a user-supplied C++ namespace better.
+       * data/c++.m4 (b4_namespace_close): Don't let it be printed
+       among the closing braces here.  This fix might make the
+       generated code easier to debug, but otherwise it should be
+       insignificant because a trailing `:' is a C++ error already.
+
+2009-05-19  Akim Demaille  <demaille@gostai.com>
+
+       remove useless variable.
+       * src/getargs.c (skeleton_arg): Remove now useless variable.
+       Should help the compiler see that this printf-like call is sane.
+
+2009-05-11  Akim Demaille  <demaille@gostai.com>
+
+       doc: use C++ headers.
+       * doc/bison.texinfo (Calc++ Scanner): Prefer C++ headers to C
+       headers.
+
+2009-05-05  Akim Demaille  <demaille@gostai.com>
+
+       fix hexadecimal token number support.
+       * src/scan-gram.l: Catch incorrect ids after hexadecimal numbers.
+
+2009-05-05  Akim Demaille  <demaille@gostai.com>
+
+       tests: check token numbers.
+       * tests/input.at (Numbered tokens): New.
+
+2009-05-04  Akim Demaille  <demaille@gostai.com>
+
+       bison: catch bad symbol names.
+       * src/scan-gram.l({int}{id}): Report as an invalid identifier.
+       * tests/input.at: Adjust.
+
+2009-05-04  Akim Demaille  <demaille@gostai.com>
+
+       space changes.
+       * src/scan-gram.l: Untabify to be robust to zealous editors.
+
+2009-05-04  Akim Demaille  <demaille@gostai.com>
+
+       identifiers: dashes are letters.
+       Dashes can now start identifiers (symbols and directives).
+
+       * src/scan-gram.l ({letter}): Add dash.
+       ({id}): Remove it.
+       * tests/input.at (Symbols): Adjust.
+       Remove stray comment.

+       * doc/bison.texinfo (Prologue Alternatives): Don't say it's
+       experimental.
+       (Decl Summary): Likewise.
