+
+	Avoid trailing spaces.
+	* data/c.m4: b4_comment(TEXT): Don't indent empty lines.
+	* data/lalr1.cc: Don't indent before rule and symbol actions, as
+	they can be empty, and anyway this incorrectly indents the first
+	action.

+	Comment changes.

+
+	Use "enum" for integral constants.
+	This is just nicer to read, I observed no speedup.
+	
+	* data/lalr1.cc (yyeof_, yylast_, yynnts_, yyempty_, yyfinal_)
+	(yterror_, yyerrcode_, yyntokens_): Define as members of an enum.
+	(yyuser_token_number_max_, yyundef_token_): Move into...
+	(yytranslate_): here.

+
+	Adjust verbose message to using emacs.

+
+	Change the handling of the symbols in the skeletons.
+	Before we were using tables which lines were the symbols and which
+	columns were things like number, tag, type-name etc.  It is was
+	difficult to extend: each time a column was added, all the numbers had
+	to be updated (you asked for colon $2, not for "tag").  Also, it was
+	hard to filter these tables when only a subset of the symbols (say the
+	tokens, or the nterms, or the tokens that have and external number
+	*and* a type-name) was of interest.
+	
+	Now instead of monolithic tables, we define one macro per cell.  For
+	instance "b4_symbol(0, tag)" is a macro name which contents is
+	self-decriptive.  The macro "b4_symbol" provides easier access to
+	these cells.
+	
+	* src/output.c (type_names_output): Remove.
+	(symbol_numbers_output, symbol_definitions_output): New.
+	(muscles_output): Call them.
+	(prepare_symbols): Define b4_symbols_number.
