+ Use them.
+
+2008-12-01 Akim Demaille <demaille@gostai.com>
+
+ Use the symbol properties to output the printer/destructor for lalr1.cc.
+ Instead of defining complex list of tuples to define various
+ properties of the symbols, we now prefer to define symbols as
+ "structs" in m4: using the symbol key (its number), and the
+ property name, b4_symbol gives it value. Use this to handle
+ destructors and printers.

+ v__ and p__ instead of v and p.
+
+2008-12-01 Akim Demaille <demaille@gostai.com>
+
+ Remove spurious empty line before syncline.
+ * data/bison.m4 (b4_syncline): Don't output an empty line before
+ the output.
+
+2008-11-26 Akim Demaille <demaille@gostai.com>
+
+ Convert lib/Makefile.am into lib/local.mk.
+ The real problem is rather gnulib.mk, which itself is extracted
+ from a Makefile.am that gnulib expects to the "recursive". The
+ tool prefix-gnulib-mk converts such a gnulib.mk to be
+ non-recursive. Also, some AC_SUBST variables need to be adjusted.
+
+ * etc/prefix-gnulib-mk: New.
+ * bootstrap (slurp): Use it to convert further gnulib.mk.
+ No longer try to avoid re-creation of lib/gnulib.mk as the changes
+ are deeper.
+ * lib/Makefile.am: Rename as...
+ * lib/local.mk: this.
+ Adjust to be prefixed.
+ * Makefile.am, configure.ac: Adjust.
+ * src/local.mk (AM_CPPFLAGS): Extend it, don't define it.

+ consistency.
+
+2008-11-25 Akim Demaille <demaille@gostai.com>

+
+ Formatting changes.
+
+2008-11-25 Akim Demaille <demaille@gostai.com>
+
+ 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.
+
+2008-11-25 Akim Demaille <demaille@gostai.com>
+
+ b4_tables_map.
+ The point is to factor the generation of the tables across skeletons.
+ This is language dependant.

+ Output the ending semicolon.
