Use strings rather than escapes when possible,
to minimize the number of warnings from xgettext.
(handle_action_dollar, handle_action_at): Don't use isdigit,
as it mishandles negative chars and it may not work as expected
outside the C locale.
src/main.c, src/relation.c, src/state.c, lib/bitset_stats.c,
lib/timevar.c.
Use src/parse-gram.y instead of src/parse-gram.c, as the gettext
manual recommends.
Similarly, use src/scan-gram.l instead of src/scan-gram.c.
(_): New macro.
(bitset_stats_set, bitset_stats_reset, bitset_stats_test): Don't
name locals "index", as it generates unnecessary warnings on some
hosts that have an "index" function.
(bitset_stats_print_1, bitset_stats_print, bitset_stats_read,
bitset_stats_write): Wrap strings in _() if they need translation.
(bitset_stats_set, bitset_stats_reset): Do not assume that bitset_word
is the same width as int.
size_t; the old version tried to do this but casted improperly.
(bitset_bindex, bitset_windex): Now size_t, not unsigned long.
(bitset_test): Now returns int, not unsigned long.
Do not assume that bitset_windex is the same width as unsigned.
(abitset_unused_clear): Do not assume that bitset_word is the same
width as int.
(abitset_op1): Use -1, not ~0, as memset arg (for portability to one's
complement hosts!).
removed.
(libbison_a_SOURCES): Add unlocked-io.h. Avoid +=, a GNU make extension.
(bitsets_sources, additional_bitsets_sources, timevars_sources): New vars.
(yyreportParseError): Use size_t for yysize.
(yy_yypstack): No longer nested inside yypstates, as nested
functions are not portable. Do not assume size_t is the
same width as int.
(yypstates): Do not assume that ptrdiff_t is the same width
as int, and similarly for yyposn and YYINDEX.
(AM_GNU_GETTEXT_VERSION): New macro, replacing GETTEXT_VERSION var.
Bump version from 0.11.2 to 0.11.5.
(BISON_PREREQ_STAGE): Remove.
(AM_GNU_GETTEXT): Use external gettext.
(AC_OUTPUT): Remove intl/Makefile.
reduced here, since anyway that computation doesn't work.

(rule_useless_p, rule_never_reduced_p): New.
(grammar_rules_partial_print): Use a filter instead of a range.
Display the title only if needed.
(grammar_rules_print): Adjust.
(grammar_rules_never_reduced_report): New.
* src/tables.c (action_row): Move the computation of rules never
reduced to...
(token_actions): here.
* src/main.c (main): Make the parser before making the report, so
that rules never reduced are computed.
Call grammar_rules_never_reduced_report.
* src/print.c (print_results): Report rules never reduced.
* tests/conflicts.at, tests/reduce.at: Adjust.
reduced by a state, attach the lookaheads to the reductions.
* src/state.h (state_t): Remove the `lookaheads',
`lookaheads_rule' member.
(reductions_t): Add a `lookaheads' member.
Use a regular array for the `rules'.
* src/state.c (reductions_new): Initialize the lookaheads member
to 0.
(state_rule_lookaheads_print): Adjust.
* src/state.h, src/state.c (state_reductions_find): New.
* src/conflicts.c (resolve_sr_conflict, set_conflicts)
(count_rr_conflicts): Adjust.
* src/lalr.c (LArule): Remove.
(add_lookback_edge): Adjust.
(state_lookaheads_count): New.
(states_lookaheads_initialize): Merge into...
(initialize_LA): this.
(lalr_free): Adjust.
* src/main.c (main): Don't free nullable and derives too early: it
is used by --verbose.
* src/print.c, src/print_graph.c, src/tables.c: Adjust.
* src/lalr.h (LA, LArule): Don't export them: used with the
state_t.
* src/lalr.c (LA, LArule): Static.
* src/lalr.h, src/lalr.c (lalr_free): New.
* src/main.c (main): Call it.
* src/tables.c (pack_vector): Check whether loc is >= to the
table_size, not >.
(pack_tables): Don't free froms, tos, conflict_tos, and pos...
(tables_generate): do it, since that's also it which allocates
them.
Don't free LA and LArule, main does.
* 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.
