+
+	Get rid of yyrhs and yyprhs in glr.c.
+	* data/glr.c (yyrhs, yyprhs): Remove.
+	Instead, use the state stack and yystos.
+
+2008-11-25  Akim Demaille  <demaille@gostai.com>
+
+	Flag glr tests.
+	* tests/local.at (_AT_BISON_OPTION_PUSHDEFS): If glr, declare it
+	as an Autotest keyword.
+
+2008-11-25  Akim Demaille  <demaille@gostai.com>
+
+	Prefer TESTSUITE_FLAGS.
+	TESTSUITEFLAGS is barely readable.
+	
+	* tests/local.mk (TESTSUITE_FLAGS): Default to $(TESTSUITEFLAGS)
+	for backward compatibility.
+	Use the former instead of the latter.

+
+	Get rid of yyrhs and yyprhs in larl1.java.
+	* data/lalr1.java (yyrhs_, yyprhs_): Remove.
+	(yy_reduce_print): Rather, use yystos_ and the state stack.

+
+	Get rid of yyrhs and yyprhs in yacc.c.
+	They were used to get the symbol types, given a rule number,  when
+	displaying the top of the stack before a reduction.  But the symbol type
+	is available from the state stack.  This has two be benefits: two tables
+	less in the parser (making it smaller), and a more consistent use of the
+	three stacks which will help to fuse them.
+	
+	* data/yacc.c (yyprhs, yyrhs): Remove.
+	(YY_REDUCE_PRINT): Pass yyssp to yy_reduce_print.
+	(yy_reduce_print): Take yyssp as argument.
+	Use it, together with yystos, to get the symbol type.
+	* tests/regression.at (Web2c Report): Remove these tables from the
+	expected output.

+
+	b4_tables_map.
+	The point is to factor the generation of the tables across skeletons.
+	This is language dependant.
+	
+	* data/c.m4 (b4_comment_): New.
+	Should be usable to define how to generate tables independently of
+	the language.
+	(b4_c_comment): New.
+	(b4_comment): Bounce to b4_c_comment.
+	Now support $2 = [PREFIX] for indentation.
+	* data/lalr1.cc (b4_table_declare): Don't output a comment if
+	there is no comment.
+	Indent it properly when there is one.
+	Output the ending semicolon.
+	(b4_table_define): Space changes.
+	Output the ending semicolon.
+	(b4_tables_map): New.
+	Use it twice instead of declaring and defining the (integral)
+	tables by hand.
