+
+	Stop using the "enum_" trick for K&R-style function definitions;
+	it confused me, and I was the author!  Instead, assume that people
+	who want to use K&R C compilers (when using these modules in GCC,
+	perhaps?) will run ansi2knr.
+
+	* lib/bbitset.h: (enum_bitset_ops, enum_bitset_type): Remove.
+	All uses of "enum_" changed to "enum ".
+	* lib/ebitset.c (enum_ebitset_find_mode): Likewise.

+	static functions simply to provide their prototypes.

+2002-10-14  Akim Demaille  <akim@epita.fr>
+
+	Version 1.75.
+
+2002-10-14  Akim Demaille  <akim@epita.fr>
+
+	* tests/Makefile.am (maintainer-check-posix): New.
+
+2002-10-14  Akim Demaille  <akim@epita.fr>
+
+	* data/glr.c [YYDEBUG] (YYLEFTMOST_STATE): Initialize the yyloc
+	member.
+
+2002-10-14  Akim Demaille  <akim@epita.fr>
+
+	* src/tables.c (table_ninf_remap): base -> tab.
+	Reported by Matt Rosing.
+
+2002-10-14  Paul Eggert  <eggert@twinsun.com>
+
+	* tests/action.at, tests/calc.at, tests/conflicts.at,
+	tests/cxx-type.at, tests/headers.at, tests/input.at,
+	tests/regression.at, tests/synclines.at, tests/torture.at:
+	Say "bison -o foo.c foo.y", not "bison foo.y -o foo.c",
+	so that the tests still work even if POSIXLY_CORRECT is set.
+	* doc/bison.texinfo (Rpcalc Compile, Invocation): Likewise.
+
+	* data/c.m4 (b4_int_type): Use yysigned_char instead of signed char,
+	for portability to K&R hosts.  Fix typo: signed char is guaranteed
+	only to 127, not to 128.
+	* data/glr.c (yysigned_char): New type.
+	* data/yacc.c (yysigned_char): Likewise.
+	* tests/regression.at (Web2c Actions): signed char -> yysigned_char.
+
+2002-10-13  Paul Eggert  <eggert@twinsun.com>
+
+	* data/yacc.c (yyparse): Rewrite to avoid "comparison is always
+	true due to limited range of data type" warning from GCC.
+
+	* data/c.m4 (b4_token_defines): Protect against double-inclusion
+	by wrapping enum yytokentype's definition inside #ifndef
+	YYTOKENTYPE.  This undoes a bug I introduced on 2002-10-12.
+
+2002-10-13  Akim Demaille  <akim@epita.fr>
+
+	* data/glr.c (yyglrShiftDefer, yyaddDeferredAction, yydoAction):
+	Un yy- yyrhs to avoid the name clash with the global YYRHS.
+
+2002-10-13  Akim Demaille  <akim@epita.fr>
+
+	* Makefile.maint: Update from Autoconf 2.54.
+	* m4/strerror_r.m4 (AC_FUNC_STRERROR_R): Remove, shipped with 2.54.
+
+2002-10-13  Akim Demaille  <akim@epita.fr>
+
+	* src/print.c (print_state): Separate the list of solved conflicts
+	from the other items.
+	* tests/conflicts.at (Resolved SR Conflicts): Adjust.
+
+2002-10-13  Akim Demaille  <akim@epita.fr>
+
+	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.
+
+	* src/tables.c (pack_table): Always create conflict_table.
+	(token_actions): Always create conflict_list.
+	* data/glr.c (YYFLAG): Remove, unused.
+
+2002-10-13  Akim Demaille  <akim@epita.fr>
+
+	* configure.ac (AC_GNU_SOURCE): Use it instead of hand written code.
+	(O0FLAGS): New.
+	(VALGRIND, GXX): New.
+	* tests/atlocal.in (CFLAGS): Use O0FLAGS.
+	* tests/bison.in: Run $PREBISON a pre-command.
+	* tests/Makefile.am (maintainer-check, maintainer-check-valgrind)
+	(maintainer-check-g++): New.
+	* Makefile.am (maintainer-check): New.
+
+2002-10-13  Akim Demaille  <akim@epita.fr>
+
+	* data/glr.c: Formatting changes.
+	Tweak some trace messages to match yacc.c's.
+
+2002-10-13  Akim Demaille  <akim@epita.fr>
+
+	GLR parsers sometimes raise parse errors instead of performing the
+	default reduction.
+	Reported by Charles-Henry de Boysson.
+
+	* tests/calc.at (_AT_CHECK_CALC, _AT_CHECK_CALC_ERROR): Don't
+	check the length of the	traces when %glr.
+	(_AT_CHECK_CALC_ERROR): Also skip `^Stack' lines, coming from
+	GLR's traces.
+	(AT_CHECK_CALC_LALR, AT_CHECK_CALC_GLR): New.
+	Test GLR parsers.
+	* data/glr.c (YYLEFTMOST_STATE): Fix its value.
+	(yyltype): Remove the yy prefix from the member names.
+	(yytable): Complete its comment.
+	(yygetLRActions): Map error action number from YYTABLE from
+	YYTABLE_NINF to 0.
+	(yyisErrorAction): No longer compare YYACTION to YYPACT_NINF
+	(which was a bug: it should have been YYTABEL_NINF, and yet it was
+	not satisfying as we could compare an YYACTION computed from
+	YYDEFACT to YYTABLE_NINF although they are unrelated): 0 is the
+	only value for error actions.
+	(yyreportParseError): In verbose parse error messages, don't issue
+	`error' in the list of expected tokens.
+	* data/yacc.c (yyparse) <yybackup>: Rewrite the decoding of the
+	next action to perform to match glr.c's decoding.
+	(yytable): Complete its comment.
+
+2002-10-13  Paul Eggert  <eggert@twinsun.com>
+
+	Fix problem reported by Henrik Grubbstroem in
+	<http://mail.gnu.org/pipermail/bug-bison/2002-October/001670.html>:
+	"nonterm: { $$ = 123; } { $$ = $1; };" was wrongly rejected,
+	because the Bison parser reads the second action before reducing
+	the first one.
+	* src/scan-gram.l (rule_length): New static var.
+	Use it to keep track of the rule length in the scanner, since
+	we can't expect the parser to be in lock-step sync with the scanner.
+	(handle_action_dollar, handle_action_at): Use this var.
+	* tests/actions.at (Exotic Dollars): Test for the problem.
+
+2002-10-12  Paul Eggert  <eggert@twinsun.com>
+
+	* lib/timevar.c [! IN_GCC && HAVE_SYS_TIME_H]: Include <sys/time.h>.
+	* m4/timevar.m4 (BISON_PREREQ_TIMEVAR): Check for <sys/time.h>.
+	Include <sys/time.h> when checking for clock_t and struct tms.
+	Use same include order as source.
+	This is for the SunOS 4.1.4 porting bug reported by Peter Klein in
+	<http://mail.gnu.org/pipermail/bug-bison/2002-October/001674.html>.
+
+	* lib/timevar.c: Update copyright date and clarify comments.
+	(get_time) [IN_GCC]: Keep the GCC version for reference.
+
+	* lib/timevar.c, lib/timevar.h, lib/timevar.def: Import
+	GCC version as of today, then merge Bison's changes.
+	Change "GCC" to "Bison" in copyright notice.  timevar.def's
+	author is Akim, so change that too.
+
+	* src/reader.c (grammar_current_rule_check):
+	Don't worry about the default action if $$ is untyped.
+	Prevents bogus warnings reported by Jim Gifford in
+	<http://mail.gnu.org/pipermail/bug-bison/2002-October/001673.html>.
+
+	* data/c.m4 (b4_token_enum): Do not define YYTOKENTYPE.
+	* data/glr.c, data/lalr1.cc, data/yacc.c:
+	Output token definitions before the first part of user declarations.
+	Fixes compatibility problem reported by Jim Gifford for kbd in
+	<http://mail.gnu.org/pipermail/bug-bison/2002-October/001672.html>.
+
+2002-10-11  Paul Eggert  <eggert@twinsun.com>
+
+	* data/yacc.c (yyreport_parse_error): Remove, putting its body into...
+	(yyparse): here.  This undoes some of the 2002-07-25 change.
+	Compatibility problem reported by Ralf S. Engelschall with
+	OSSP cfg <http://www.ossp.org/pkg/lib/cfg/>.
+
+2002-10-11  Akim Demaille  <akim@epita.fr>
+
+	* tests/regression.at Characters Escapes): New.
+	* src/scan-gram.l (SC_ESCAPED_CHARACTER): Accept \' in strings and
+	characters.
+	Reported by Jan Nieuwenhuizen.
+
+2002-10-11  Akim Demaille  <akim@epita.fr>
+
+	* po/id.po: New.
+
+2002-10-10  Paul Eggert  <eggert@twinsun.com>
+
+	Portability fixes for bitsets; this also avoids several GCC
+	warnings.
+
+	* lib/abitset.c: Include <stddef.h>, for offsetof.
+	* lib/lbitset.c: Likewise.
+
+	* lib/abitset.c (abitset_bytes): Return a size that is aligned
+	properly for vectors of objects.  Do not assume that adding a
+	header size to a multiple of a word size yields a value that is
+	properly aligned for the whole union.
+	* lib/bitsetv.c (bitsetv_alloc): Likewise.
+
+	* lib/bitset_stats.c (bitset_stats_bytes): Adjust to new,
+	unique names for structures.
+	* lib/ebitset.c (ebitset_bytes): Likewise.
+	* lib/lbitset.c (lbitset_bytes): Likewise.
+
+	* lib/abitset.c (abitset_ones, abitset_zero, abitset_empty_p,

+	abitset_xor_cmp, abitset_and_or, abitset_and_or_cmp,
+	abitset_andn_or, abitset_andn_or_cmp, abitset_or_and,
+	abitset_or_and_cmp, abitset_copy): Supply prototype decls,
+	to improve the type-checking that GCC can do.
+	* lib/bitset.c (bitset_op4_cmp): Likewise.
+	* lib/bitset_stats.c (bitset_stats_count,
+	bitset_stats_empty_p, bitset_stats_ones, bitset_stats_zero,

+	bitset_stats_andn_or_cmp, bitset_stats_or_and,
+	bitset_stats_or_and_cmp): Likewise.

+	lbitset_xor_cmp, lbitset_empty_p, lbitset_ones, lbitset_not,
+	lbitset_subset_p, lbitset_disjoint_p, debug_lbitset): Likewise.
+
+	* lib/abitset.h: Include bitset.h, not bbitset.h.
+	* lib/ebitset.h: Likewise.
+	* lib/lbitset.h: Likewise.
+
+	* lib/bbitset.h: (enum_bitset_ops, enum_bitset_type): New types.
+	All instances of parameters of type enum bitset_opts are now of
+	type enum_bitset_opts, to conform to the C Standard, and similarly
+	for enum_bitset_type.
+	* lib/ebitset.c (enum_ebitset_find_mode): Likewise.
+	* lib/lbitset.c (enum_lbitset_find_mode): Likewise.
+
+	Do not use "struct bitset_struct" to mean different things in
+	different modules.  Not only is this confusing, it violates
+	the C Standard, which requires that structure types in different
+	modules must be compatible if one is to be passed to the other.
+	* lib/bbitset.h (bitset): Now points to a union, not to a struct.
+	All instances of "struct bitset_struct *" replaced with "bitset".
+	* lib/bitset.h (struct bitset_struct): Remove, replacing with....
+	(union bitset_union, struct abitset_struct, struct ebitset_struct,

+	* lib/ebitset.c (struct ebitset_struct, ebitset, struct
+	bitset_struct): Remove.
+	* lib/lbitset.c (struct lbitset_struct, lbitset, bitset_struct):
+	Likewise.
+
+	Do not call a function of type T using a call that assumes the
+	function is of a different type U.  Standard C requires that a
+	function must be called with a type that is compatible with its
+	definition.
+	* lib/bbitset.h (bitset_and_or_, bitset_andn_or_, bitset_or_and_):
+	New decls.
+	* lib/bitset.c (bitset_and_or_, bitset_andn_or_, bitset_or_and_):
+	New functions.

+	GCC warning.
+	* lib/lbitset.c (LBITSET_CURRENT1): Likewise.
+	Use offsetof, for simplicity.
+
+2002-10-06  Paul Eggert  <eggert@twinsun.com>
+
+	* lib/bitset.h (bitset_reset): Do not assume that bitset_word is
+	the same width as int.  This reapplies a hunk of the 2002-08-12 patch
+	<http://mail.gnu.org/pipermail/bison-patches/2002-August/001111.html>,
+	which was inadvertently undone by the 2002-09-30 patch.
+	* lib/lbitset.c (debug_lbitset): Do not assume that bitset_word is
+	the same width as int.
+
+2002-10-04  Paul Eggert  <eggert@twinsun.com>
+
+	Version 1.50.
+
+	* configure.ac (AC_INIT), NEWS: Increment version number.
+
+	* doc/bison.texinfo: Minor spelling, grammar, and white space
+	fixes.
+	(Symbols): Mention that any negative value returned from yylex
+	signifies end-of-input.  Warn about negative chars.  Mention
+	the portable Standard C character set.
+
+	The GNU coding standard says CFLAGS and YFLAGS are reserved
+	for the installer to set.
+	* lib/Makefile.am (AM_CFLAGS): Renamed from CFLAGS.
+	* src/Makefile.am (AM_CFLAGS): Likewise.

+	* src/symtab.h (SYMBOL_NUMBER_MAX): New macro.
+	* src/reader.c (reader): Use it.
+
+	* tests/regression.at (Braces parsing): Use grep, not fgrep, as
+	POSIX 1003.1-2001 has removed fgrep.
+
+2002-10-04  Michael Hayes  <m.hayes@elec.canterbury.ac.nz>
+
+	* lib/bbitset.h (BITSET_WINDEX_MAX): Redefine so that it cannot be
+	interpreted as signed.

+
+	* lib/abitset.c (struct abitset_struct.n_bits, abitset_small_list,
