+       * src/lalr.c (add_lookback_edge): Use state_t instead of ints.
+       (build_relations): Adjust.

+
+       * src/lalr.c (set_goto_map): Remove a wrong but benign loop
+       duplication.
+
+

+
+       * src/reader.c (packgram): Catch nitems overflows.

+
+       * src/files.c, src/files.h (guard_obstack): Remove.
+       * src/output.c (output): Adjust.
+       * src/reader.c (parse_braces): New, factoring...
+       (copy_action, copy_guard): these two which are renamed as...
+       (parse_action, parse_guard): these.
+       As a voluntary consequence, using braces around guards is now
+       mandatory.

+
+       * src/gram.h (rule_t): `guard' and `guard_line' are new members.
+       * src/reader.c (symbol_list): `guard' and `guard_line' are new
+       members.
+       (symbol_list_new): Adjust.
+       (copy_action): action_line is the first line, not the last.
+       (copy_guard): Just as for actions, store the `action' only, not
+       the switch/case/break flesh.
+       Don't parse the user action that might follow the guard, let...
+       (readgram): do it, i.e., now, there can be an action after a
+       guard.
+       In other words the guard is just explicitly optional.
+       (packgram): Adjust.
+       * src/output.c (guards_output): New.
+       (output_parser): Call it when needed.
+       (output): Also free the guard and attrs obstacks.
+       * src/files.c, src/files.h (obstack_save): Remove.
+       (output_files): Remove.
+       As a result, if one needs the former `.act' file, using an
+       appropriate skeleton which requires actions and guards is now
+       required.
+       * src/main.c (main): Adjust.
+       * tests/semantic.at: New.
+       * tests/regression.at: Use `input.y' as input file name.
+       Avoid 8+3 problems by requiring input.c when the test needs the
+       parser.

+
+       * src/reader.c (symbol_list_new): Be sure to initialize all the
+       fields.

        All the hacks using a final pseudo state are now useless.
