+
+       Normalize conflict related messages.
+
+       * src/complain.h, src/complain.c (warn, complain): New.
+       * src/conflicts.c (conflicts_print): Use them.
+       (conflict_report_yacc): New, extracted from...
+       (conflicts_print): here.
+       * tests/conflicts.at, tests/existing.at: Adjust.

+
+       Report rules which are never reduced by the parser: those hidden
+       by conflicts.
+
+       * src/LR0.c (save_reductions): Don't make the final state too
+       different: save its reduction (accept) instead of having a state
+       without any action (no shift or goto, no reduce).
+       Note: the final state is now a ``regular'' state, i.e., the
+       parsers now contain `reduce 0' as default reduction.
+       Nevertheless, since they decide to `accept' when yystate =
+       final_state, they still will not reduce rule 0.
+       * src/print.c (print_actions, print_reduction): Adjust.
+       * src/output.c (action_row): Track reduced rules.
+       (token_actions): Report rules never reduced.
+       * tests/conflicts.at, tests/regression.at: Adjust.

+
+       `stage' was accidently included in a previous patch.
+       Initiate its autoconfiscation.
+
+       * configure.in: Look for malloc.h and sys/times.h.
+       * src/main.c (stage): Adjust.
+       Report only when trace_flag.

        * src/state.h, src/state.c (transitions_t): Holds state_t*'s, not
