+
+       * src/getargs.h (enum trace_e): New.
+       * src/getargs.c (trace_args, trace_types, trace_argmatch): New.
+       (long_options, short_options): --trace/-T takes an optional
+       argument.
+       Change all the uses of trace_flag to reflect the new flags.
+       * tests/sets.at (Firsts, Nullable, Broken Closure): Use --trace=sets.
+
+       Strengthen `stage' portability.
+
+       * m4/stage.m4 (BISON_PREREQ_STAGE): New.
+       * configure.in: Use it.
+       Don't check for malloc.h and sys/times.h.
+       * src/system.h: Include them when appropriate.
+       * src/main.c (stage): Compile only when mallinfo, struct mallinfo,
+       times and struct tms are available.

+       * tests/calc.at (Calculator $1): Adjust.
+       * data/yacc.c, data/glr.c, data/lalr1.c: When making the verbose
+       error message, do not report the parser accepts the error token in
+       that state.
