+       * src/LR0.c (allocate_itemsets): Don't loop over ritem: loop over
+       the RHS of the rules.
+       * src/output.c (output_gram): Likewise.

+
+       * src/gram.h (rule_t): `lhs' is now a pointer to the symbol's
+       bucket.
+       Adjust all dependencies.
+       * src/reduce.c (nonterminals_reduce): Don't forget to renumber the
+       `number' of the buckets too.
+       * src/gram.h: Include `symtab.h'.
+       (associativity): Move to...
+       * src/symtab.h: here.
+       No longer include `gram.h'.

+
+       * src/gram.h, src/gram.c (rules_rhs_length): New.
+       (ritem_longest_rhs): Use it.
+       * src/gram.h (rule_t): `number' is a new member.
+       * src/reader.c (packgram): Set it.
+       * src/reduce.c (reduce_grammar_tables): Move the useless rules at
+       the end of `rules', and count them out of `nrules'.
+       (reduce_output, dump_grammar): Adjust.
+       * src/print.c (print_grammar): It is no longer needed to check for
+       the usefulness of a rule, as useless rules are beyond `nrules + 1'.
+       * tests/reduce.at (Reduced Automaton): New test.

        * src/reduce.c (inaccessable_symbols): Fix a buglet: because of a
        lacking `+ 1' to nrules, Bison reported as useless a token if it
        was used solely to set the precedence of the last rule...

        * data/bison.c++, data/bison.simple: Don't output the current file
        name in #line, to avoid useless diffs between two identical
        outputs under different names.

        Normalize loops to using `< nrules + 1', not `<= nrules'.
