+	(stack_symbol_type): Declare constructor and other operations as
+	inline.
+	(yy_destroy_): Inline.

+2008-11-09  Akim Demaille  <demaille@gostai.com>
+
+	Introduce a hierarchy for symbols.
+	* data/lalr1.cc (symbol_base_type, symbol_type): New.
+	(data_type): Rename as...
+	(stack_symbol_type): this.
+	Derive from symbol_base_type.
+	(yy_symbol_value_print_): Merge into...
+	(yy_symbol_print_): this.

+	(yy_print_): this.
+	(yydestruct_): Rename as...
+	(yy_destroy_): this.
+	(b4_symbols_actions, YY_SYMBOL_PRINT): Adjust.
+	(parser::parse): yyla is now of symbol_type.
+	Use its type member instead of yytoken.

+
+	Handle semantic value and location together.
+	* data/lalr1.cc (b4_symbol_actions): Bounce $$ and @$ to
+	yydata.value and yydata.location.
+	(yy_symbol_value_print_, yy_symbol_print_, yydestruct_)
+	(YY_SYMBOL_PRINT): Now take semantic value and location as a
+	single arg.
+	Adjust all callers.
+	(yydestruct_): New overload for a stack symbol.

+	Rely on the state stack to display reduction traces.
+	To display rhs symbols before a reduction, we used information about the rule
+	reduced, which required the tables yyrhs and yyprhs.  Now use rely only on the
