+
+       * src/reduce.c (reduce_grammar): When the language is empty,
+       complain about the start symbol, not the axiom.
+       Use its location.
+       * tests/reduce.at (Empty Language): New.

+
+       * src/reader.h, src/reader.c (gram_error): ... can't get
+       yycontrol without making too strong assumptions on the parser
+       itself.
+       * src/output.c (prepare_tokens): Use the real 0th value of
+       token_translations instead of `0'.
+       * src/parse-gram.y (yyerror): Don't rely on yycontrol being
+       visible here.
+       * data/yacc.c (yyreport_parse_error): Rename yylocation as yylloc
+       for the time being: %locations ought to provide it to yyerror.

+
+       * src/output.c (prepare_tokens): Go up to ntokens, not ntokens + 1.
+       * doc/bison.texinfo (Decl Summary): s/$illegal/$undefined./.
+       * tests/regression.at (Web2c Actions): Adjust.

+
+       Stop storing rules from 1 to nrules + 1.
+
+       * src/LR0.c, src/closure.c, src/derives.c, src/gram.c, src/lalr.c
+       * src/nullable.c, src/output.c, src/print.c, src/reader.c
+       * src/reduce.c: Allocate and free from &rules[0], not &rules[1].
+       Iterate from 0 to nrules.
+       Use rule_number_as_item_number and item_number_as_rule_number.
+       Adjust to `derive' now containing possibly 0.
+       * src/gram.h (rule_number_as_item_number, item_number_as_rule_number):
+       Handle the `- 1' part in rule numbers from/to item numbers.
+       * src/conflicts.c (log_resolution): Fix the message which reversed
+       shift and reduce.
+       * src/output.c (action_row): Initialize default_rule to -1.
+       (token_actions): Adjust.
+       * tests/sets.at (Nullable, Firsts): Fix the previously bogus
+       expected output.
+       * tests/conflicts.at (Resolved SR Conflicts): Likewise.

+       (b4_c_knr_arg_decl): New.
+       * data/yacc.c: Use it to define yysymprint, yydestruct, and
+       yyreport_parse_error.
