+ Update TODO.
+ * TODO (-D): is implemented.
+ (associativity): Same precedence must have the same associativity.
+ For instance, how can a * b / c be parsed if * is %left and / is
+ %right?
+ (YYERRORCODE, YYFAIL, YYBACKUP): New.

+
+ More information about the symbols.
+ * src/output.c (type_names_output): Document all the symbols,
+ including those that don't have a type-name.
+ (symbol_definitions_output): Define "is_token" and
+ "has_type_name".
+ * data/lalr1.cc (b4_type_action_): Skip symbols that have an empty
+ type-name, now that they are defined too in b4_type_names.

+
+ Make parser::yytranslate static.
+ Small speedup (1%) on the list grammar. And makes yytranslate_ available
+ in non member functions.
+
+ * data/lalr1.cc (yytranslate_): Does not need to be a instance
+ function.

+
+ 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.

+
+ 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.

+
+ Add %precedence support.
+ Unfortunately it is not possible to reuse the %prec directive. This
+ is because to please POSIX, we do not require to end the rules with a
+ semicolon. As a result,
+
+ foo: bar %prec baz
+
+ is ambiguous: either a rule which precedence is that of baz, or a rule,
+ and then a declaration of the precedence of the token baz.

+ * src/assoc.h, src/assoc.c (precedence_assoc): New.
