+ Let nondeterministic skeletons be usable with deterministic
+ tables.
+
+ With the patch, GAWK compiled by GCC without -O2 passes its test
+ suite using a GLR parser driven by LALR tables. It fails with -O2
+ because `struct stat' gives two different answers on my machine:
+ 88 (definition of an auto var) and later 96 (memset on this var).
+ Hence the stack is badly corrumpted. The headers inclusion is to
+ blame: if I move the awk.h inclusion before GLR's system header
+ inclusion, the two struct stat have the same size.

+
+ * Makefile.am (SUBDIRS): Remove intl.
+ (DISTCLEANFILES): Remove.

+ PROTOTYPES to check for prototypes, and "defined __STDC__" to
+ check for void *.
+
+ * lib/bbitset.h (BITSET_WORD_BITS): Now of type unsigned, not
+ 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.
+
+ * lib/bitset_stats.c: Include "gettext.h".
+ (_): 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.
+
+ * lib/bitset_stats.c (bitset_stats_print_1, bitset_stats_print,
+ bitset_stats_read, bitset_stats_write): Wrap strings in _() if

+ 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.
+
+ * src/complain.c (strerror_r): Remove decl; not needed.

+ as it mishandles negative chars and it may not work as expected
+ outside the C locale.
+
+ * src/symtab.c (symbol_get): Don't cast LHS of an assignment;
+ this is a GCC extension and is not portable to other compilers.
+
+ * src/system.h (alloca): Use same pattern as ../lib/error.c.

+ Do not include <malloc.h>; no longer needed (and generates
+ warnings on OpenBSD 3.0).
+
+ * tests/cxx-type.at (yylex): Do not pass signed char to isupper;
+ it's not portable.
+
+ * tests/regression.at: Do not use 'cc -c input.c -o input';
+ Sun C rejects this. Instead, use 'cc -c input.c -o input.o'.
+
+ * tests/synclines.at (AC_SYNCLINES_COMPILE): Accept any nonzero
+ exit status as failure, not just exit status 1. Sun C exits
+ with status 2 sometimes.
+
+ * tests/torture.at (AT_INCREASE_DATA_SIZE): New macro.

+
+2002-08-02 Akim Demaille <akim@epita.fr>

+
+2002-08-01 Akim Demaille <akim@epita.fr>

+
+ * src/state.h (state_t): Remove the `lookaheads',
+ `lookaheads_rule' member.

+
+2002-07-31 Akim Demaille <akim@epita.fr>
+
+ Let --trace have arguments.
+
+ * 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.

+
+ 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/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.
