+
+	When reducing initial empty rules, Bison parser read an initial
+	location that is not defined.  This results in garbage, and that
+	affects Bison's own parser.  Therefore we need (i) to extend Bison
+	to support a means to initialize this location, and (ii) to use
+	this CVS Bison to fix CVS Bison's parser.
+
+	* src/reader.h, reader.c (epilogue_augment): Remove, replace
+	with...
+	* src/muscle_tab.h, src/muscle_tab.c (muscle_code_grow): this.
+	* src/parse-gram.y: Adjust.
+	(%initial-action): New.
+	(%error-verbose): Since we require CVS Bison, there is no reason
+	not to use it.
+	* src/scan-gram.l: Adjust.
+	* src/Makefile.am (YACC): New, to make sure we use our own parser.
+	* data/yacc.c (yyparse): Use b4_initial_action.
+
+2003-08-25  Akim Demaille  <akim@epita.fr>
+
+	* doc/bison.texinfo: Don't promote stdout for error messages.
+
+2003-08-25  Akim Demaille  <akim@epita.fr>
+
+	* data/lalr1.cc (Parser::reduce_print_): Remove unused yyi.
+	From Alexandre Duret-Lutz.
+
+2003-08-25  Akim Demaille  <akim@epita.fr>
+
+	* data/lalr1.cc (Parser::stack_print_, YY_STACK_PRINT): New.
+	Use them.
+
+2003-08-25  Akim Demaille  <akim@epita.fr>
+
+	* data/lalr1.cc (Parser::reduce_print_): New.
+	Use it.
+
+2003-08-25  Akim Demaille  <akim@epita.fr>
+
+	Have lalr1.cc catch with Paul Eggert's patch to fix the infinite
+	error recovery loops.  This patch is based on
+	<http://mail.gnu.org/archive/html/bison-patches/2003-06/msg00000.html>.
+	Also, augment the similarity between lalr1.cc and yacc.c.
+	Note: the locations of error recovery rules are not correct yet.
+
+	* data/lalr1.cc: Comment changes to augment the similarity between
+	lalr1.cc and yacc.c.
+	(YYERROR): Goto to yyerrorlab, not yyerrlab1.
+	(yyerrlab1): Remove, but where it used to be (now the bottom part of
+	yyerrlab), when hitting EOF, pop the whole stack here instead of
+	merely falling thru the default error handling mechanism.
+	(yyerrorlab): New label, with the old contents of YYERROR,
+	plus the following change: pop the stack of rhs corresponding
+	to the production that invoked YYERROR.  That is how Yacc
+	behaves (required by POSIX).
+	* tests/calc.at (AT_CHECK_CALC_LALR1_CC): No longer expected to
+	fail.
+
+2003-08-25  Akim Demaille  <akim@epita.fr>
+
+	Tune local.at so that people can "autom4te -l autotest calc.at -o
+	calc" for instance, to extract a sub test suite.
+
+	* tests/testsuite.at: Move the initialization, Autotest version
+	requirement, and AT_TESTED invocation into...
+	* tests/local.at: here.
+	* tests/testsuite.at: Include it for compatibility with Autoconf
+	2.57.
+	* tests/Makefile.am ($(TESTSUITE)): Report that the warning should
+	be ignore.
+
+2003-08-04  Paul Eggert  <eggert@twinsun.com>
+
+	Rework code slightly to avoid gcc -Wtraditional warnings.
+	* data/glr.c (yyuserMerge): Return void, not YYSTYPE.
+	The returned value is now stored in *YY0.  All callers changed.
+	* src/output.c (merge_output): Adjust to the above change.
+
+2003-07-26  Paul Eggert  <eggert@twinsun.com>
+
+	* data/glr.c (YYASSERT): New macro.
+	(yyfillin, yydoAction, yyglrReduce, yysplitStack,
+	yyresolveStates, yyprocessOneStack):
+	Use `YYASSERT (FOO);' rather than `if (! (FOO)) abort ();'.
+	Derived from a suggestion by Frank Heckenbach.
+
+2003-07-25  Paul Eggert  <eggert@twinsun.com>
+
+	* data/glr.c (yyglrReduce): Don't use C89 string concatenation,
+	for portability to K&R C (after ansi2knr, presumably).  See
+	<http://mail.gnu.org/archive/html/bison-patches/2003-06/msg00041.html>
+	by Frank Heckenbach, though I have omitted the structure-initialization
+	part of his glr-knr.diff patch since I recall that the Portable
+	C Compiler didn't require that change.
+
+	Let the user specify how to allocate and free memory.
+	Derived from a suggestion by Frank Heckenbach in
+	<http://mail.gnu.org/archive/html/bison-patches/2003-06/msg00041.html>.
+	* data/glr.c (YYFREE, YYMALLOC, YYREALLOC): New macros.
+	All uses of free, malloc, realloc changed to use these macros,
+	and unnecessary casts removed.
+	* data/yacc.c (YYFREE, YYMALLOC): Likewise.
+
+2003-07-06  Matthias Mann  <MatthiasMann@gmx.de>
+
+	* data/lalr1.cc (operator<<(std::ostream&, const Position&)):
+	use s.empty() rather than s == "" to test for empty string; see
+	<http://mail.gnu.org/archive/html/bison-patches/2003-07/msg00003.html>
+	(trivial change)
+
+2003-06-25  Akim Demaille  <akim@epita.fr>
+
+	* config/depcomp, config/install-sh: Update from masters.
+
+2003-06-20  Paul Eggert  <eggert@twinsun.com>
+
+	* data/glr.c (YYLLOC_DEFAULT): Parenthesize arguments as needed,
+	and return properly parenthesized result.
+	* data/lalar1.cc (YYLLOC_DEFAULT): Likewise.
+	* data/yacc.c (YYLLOC_DEFAULT): Likewise.
+	Remove unnecessary parentheses from uses.
+	* doc/bison.texinfo (Location Default Action): Describe the
+	conventions for parentheses.
+
+2003-06-19  Paul Eggert  <eggert@twinsun.com>
+
+	* data/glr.c (yyremoveDeletes, yy_reduce_print, yyglrReduce,
+	yyreportTree): Do not assume that size_t is the same width as int,
+	when printing sizes.  Print sizes using an unsigned format.
+	Problem reported by Frank Heckenbach in
+	<http://mail.gnu.org/archive/html/bison-patches/2003-06/msg00035.html>.
+
+	Port to Forte Developer 7 C compiler.
+	* data/glr.c (struct YYLTYPE): If locations are not being used,
+	declare a single dummy member, as empty structs do not conform
+	to the C standard.
+	(YYERROR, YYBACKUP): Do not use "do { ...; return foo; } while (0)";
+	the Forte Developer 7 C compiler complains that end-of-loop
+	code is not reached.
+
+2003-06-17  Paul Eggert  <eggert@twinsun.com>
+
+	* lib/libiberty.h (PARAMS): Spell argument as Args, not as X, to
+	avoid warnings from picky compilers about redefinition of PARAMS.
+
+2003-06-17  Paul Eggert  <eggert@twinsun.com>
+
+	Version 1.875b.
+
+	* NEWS: Document 1.875b.
+
+	* lib/bbitset.h: Do not include config.h; that's the includer's job.
+	Do not include <sys/types.h>; shouldn't be needed on a C89 host.
+	* lib/bitset.h (bitset_compatible_p): Indent as per GNU standard.
+	Don't use 'index' in comments, as it's a builtin fn on some hosts.
+	* lib/bitset_stats.c: Include gettext.h unconditionally, as
+	per recent gettext manual's suggestion.
+	* lib/ebitset.c (ebitset_resize, ebitset_unused_clear):
+	Use prototypes, not old-style definitions.
+	* lib/lbitset.c (lbitset_unused_clear): Likewise.
+	* lib/vbitset.c (vbitset_resize, vbitset_ones, vbitset_zero,
+	vbitset_empty_p, vbitset_copy1, vbitset_not, vbitset_equal_p,
+	vbitset_subset_p, vbitset_disjoint_p, vbitset_and, vbitset_and_cmp,
+	vbitset_andn, vbitset_andn_cmp, vbitset_or, vbitset_or_cmp,

+	vbitset_andn_or, vbitset_andn_or_cmp, vbitset_or_and,
+	vbitset_or_and_cmp, vbitset_copy): Likewise.
+
+	* lib/libiberty.h: Do not include config.h; that's the includer's job.
+	Do not include <stdlib.h>.
+	(PARAMS): Define unconditionally for C89.
+	(ATTRIBUTE_NORETURN): Remove.
+	(ATTRIBUTE_UNUSED): Define unconditionally.
+
+	Upgrade to 2003-06-08 libbitset, submitted by Michael Hayes in:

+	* lib/abitset.c, lib/bbitset.h, lib/bitset.c, lib/bitset.h,
+	lib/bitset_stats.c, lib/ebitset.c, lib/lbitset.c: Import
+	from libbitset.
+
+	* doc/bison.texinfo (How Can I Reset the Parser): Renamed from
+	`How Can I Reset @code{yyparse}', since texinfo does not allow
+	arbitrary @ in node names.
+
+	* m4/Makefile.am (EXTRA_DIST): Add the following files, which
+	shouldn't be needed according to the gettext 0.12.1 documentation
+	but which seem to be needed anyway: codeset.m4 glibc21.m4
+	intdiv0.m4 inttypes-pri.m4 inttypes.m4 inttypes_h.m4 isc-posix.m4
+	lcmessage.m4 nls.m4 po.m4 stdint_h.m4 uintmax_t.m4 ulonglong.m4.

+	AC_HEADER_STDBOOL.
+	(AM_GNU_GETTEXT): Put brackets around args, as latest manual suggests.
+	(AM_GNU_GETTEXT_VERSION): Update to 0.12.1.
+	* lib/Makefile.am (EXTRA_DIST): Add stdbool_.h.
+	(MOSTLYCLEANFILES): New var.
+	($(libbison_a_OBJECTS)): Depend on $(STDBOOL_H).
+	(stdbool.h): New rule.

+
+	* tests/calc.at (AT_CHECK_CALC): New option EXPECTED-TO-FAIL.
+	(AT_CHECK_CALC_LALR1_CC): Use it, since the C++ LALR parser fails
+	the tests right now.
+	* tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Ensure yylex and
+	yyerror are declared before use; C99 requires this.
+
+2003-06-09  Paul Hilfinger  <Hilfinger@CS.Berkeley.EDU>
+
+	* data/glr.c (YYERROR): Update definition to reset yyerrState to 0
+	first.
+	(yyrecoverSyntaxError): Correct the logic for setting and testing
+	yyerrState.
+	Correct comment on handling EOF.
+	Allow states with only a default reduction, rather than failing
+	(I can't quite reconstruct why these were not allowed before).
+
+	Fixes to avoid problem that $-N rules in GLR parsers can cause
+	buffer overruns, corrupting state.
+
+	* src/output.c (prepare_rules): Output max_left_semantic_context
+	definition.
+	* src/reader.h (max_left_semantic_context): New variable declaration.
+	* src/scan-gram.l (max_left_semantic_context): Define.
+	(handle_action_dollar): Update max_left_semantic_context.
+	* data/glr.c (YYMAXLEFT): New definition.
+	(yydoAction): Increase size of yyrhsVals by YYMAXLEFT.
+	(yyresolveAction): Ditto.
+

+
+	* data/glr.c (YYLTYPE): Make trivial if locations not used.
+	(YYRHSLOC): Add parentheses, and define only if locations used.
+	(YYLLOC_DEFAULT): Add parentheses, and give trivial definition if
+	locations not used.
+	(yyuserAction): Use YYLLOC_DEFAULT to set *yylocp.
+	(yydoAction): Remove redundant initialization of *yyvalp and *yylocp.
+
+	* tests/cxx-type.at: Exercise location information; update tests
+	to differentiate output with and without locations.
+	Remove forward declarations of yylex and yyerror---caused errors
+	because default YYLTYPE not yet defined.
+	Change semantic actions to compute strings, rather than printing
+	them directly (to test proper passing of semantics values).  Change
+	output to prefix notation and update test data and expected results.
+	(yylex): Track locations.
+	(stmtMerge): Return value rather than printing, and include arguments
+	in value.
+
+2003-06-03  Paul Eggert  <eggert@twinsun.com>
+
+	Avoid warnings generated by GCC 2.95.4 when Bison is
+	configured with --enable-gcc-warnings.
+	* data/lalr1.cc (yy::]b4_parser_class_name[::parse,
+	yy::]b4_parser_class_name[::translate_,
+	yy::Stack::operator[] (unsigned),
+	yy::Stack::operator[] (unsigned) const,
+	yy::Slice::operator[] (unsigned),
+	yy::Slice::operator[] (unsigned) const):
+	Rename local vars to avoid warnings.
+	* tests/glr-regression.at (Improper handling of embedded actions
+	and $-N in GLR parsers): Remove unused local variable from yylex.
+	* tests/regression.at (_AT_DATA_DANCER_Y): Declare yylex to take
+	(void) as arg when not pure, since we now assume C89 when building
+	Bison.  Pacify GCC by using parameter.
+
+2003-06-02  Paul Eggert  <eggert@twinsun.com>
+
+	* data/lalr1.cc (yy::Position::lines, yy::Position::columns,
+	yy::Location::lines, yy::Location::columns): Rename arguments
+	to avoid shadowing; this removes a warning generated by GCC 3.3.
+
+2003-06-01  Paul Eggert  <eggert@twinsun.com>
+
+	Don't pass C-only warning optins (e.g., -Wmissing-declarations)
+	to g++, as GCC 3.3 complains if you do it.
+	* configure.ac (WARNING_CXXFLAGS): New subst.  Set it to
+	everything that WARNING_CFLAGS has, except omit warnings
+	not suitable for C++.
+	(AC_PROG_CXX): Use this instead of AC_CHECK_PROGS([CXX], [g++]).
+	* tests/atlocal.in (CXXFLAGS): New var.
+	* tests/local.at (AT_COMPILE_CXX): Use it instead of CFLAGS.
+
+	Fix a GLR parser bug I reported in February; see
+	<http://mail.gnu.org/archive/html/bison-patches/2003-02/msg00008.html>.
+	The problem was that GLR parsers did not conform to the C standard,
+	because actions like { $1 = $2 + $3; } expanded to expressions
+	that invoked YYFILL in separate subexpressions, and YYFILL assigned
+	to a local variable.  The C standard says that expressions
+	like (var = f ()) + (var = f ()) have undefined behavior.
+	Another problem was that GCC sometimes issues warnings that
+	yyfill and its parameters are unused.
+
+	* data/glr.c (yyfillin): Renamed from the old yyfill.  Mark
+	as possibly unused.
+	(yyfill): New function.
+	(YYFILL): Use it.
+	(yyuserAction): Change type of yynormal to bool, so that it matches
+	the new yyfill signature.  Mark it as possibly unused.
+
+
+	Follow up on a bug I reported in February, where a Bison-generated
+	parser can loop.  Provide a test case and a fix for yacc.c.  I
+	don't have a fix for lalr1.cc or for glr.c, unfortunately.
+	The original bug report is in:
+	<http://mail.gnu.org/archive/html/bison-patches/2003-02/msg00044.html>
+
+	* data/yacc.c (YYERROR): Now just 'goto yyerrorlab', since the
+	macro's size was becoming unwieldy.
+	(yyerrlab): Do not discard an empty lookahead symbol, as this
+	might destroy garbage.
+	(yyerrorlab): New label, with the old contents of YYERROR,
+	plus the following change: pop the stack of rhs corresponding
+	to the production that invoked YYERROR.  That is how Yacc
+	behaves, and POSIX requires this behavior.
+	(yyerrlab1): Use YYPOPSTACK instead of its definiens.
+	* tests/calc.at (_AT_DATA_CALC_Y): Include unistd.h if available.
+	Define 'alarm' to do nothing if unistd.h is not available.
+	Add a new rule "exp: '-' error;" to test the above change to
+	data/yacc.c.  Use 'alarm' to abort any test taking longer than
+	10 seconds, as it's probably looping.
+	(AT_CHECK_CALC): Test recovery from error in new grammar rule.
+	Also, the new yacc.c generates two fewer diagnostics for an
+	existing test.
+
+2003-05-24  Paul Eggert  <eggert@twinsun.com>
+
+	* data/glr.c (YYSTACKEXPANDABLE): Do not evaluate
+	YYSTYPE_IS_TRIVIAL or YYSTYPE_IS_TRIVIAL unless they are defined.
+	This fixes a problem reported by John Bowman when the Compaq/HP
+	Alpha cxx compiler happy (e.g. using cxx -D__USE_STD_IOSTREAM
+	-ansi -Wall -gall).
+	* data/yacc.c (union yyalloc): Likewise.
+	(YYCOPY): Do not evaluate __GNUC__ unless it is defined.
+
+	Switch from 'int' to 'bool' where that makes sense.
+
+	* lib/abitset.c (abitset_test, abitset_empty_p, abitset_equal_p,
+	abitset_subset_p, abitset_disjoint_p, abitset_and_cmp,
+	abitset_andn_cmp, abitset_or_cmp, abitset_xor_cmp, abitset_and_or,
+	abitset_and_or_cmp, abitset_andn_or_cmp, abitset_or_and_cmp):
+	Return or accept bool, not int.  All callers changed.
+	* lib/bbitset.h: (bitset_toggle_, bitset_copy_, bitset_and_or_cmp_,
+	bitset_andn_or_cmp_, bitset_or_and_cmp_): Likewise.
+	* lib/bitset.c (bitset_only_set_p, bitset_print, bitset_toggle_,

+	bitset_stats_and_or_cmp, bitset_stats_andn_or_cmp,
+	bitset_stats_or_and_cmp): Likewise.
+	* lib/ebitset.c (ebitset_elt_zero_p, ebitset_equal_p, ebitset_copy_cmp,
+	ebitset_test, ebitset_empty_p, ebitset_subset_p, ebitset_disjoint_p,
+	ebitset_op3_cmp, ebitset_and_cmp, ebitset_andn_cmp, ebitset_or_cmp,
+	ebitset_xor_cmp): Likewise.
+	* lib/lbitset.c (lbitset_elt_zero_p, lbitset_equal_p, lbitset_copy_cmp,
+	lbitset_test, lbitset_empty_p, lbitset_subset_p, lbitset_disjoint_p,
+	lbitset_op3_cmp, lbitset_and_cmp, lbitset_andn_cmp, lbitset_or_cmp,
+	lbitset_xor_cmp): Likewise.
+	* lib/bbitset.h: Include <stdbool.h>.
+	(struct bitset_vtable): The following members now return bool, not
+	int: toggle, test, empty_p, disjoint_p, equal_p, subset_p,
+	and_cmp, andn_cmp, or_cmp, xor_cmp, and_or_cmp, andn_or_cmp,
+	or_and_cmp).
+	* src/conflicts.c (count_rr_conflicts): Likewise.
+	* lib/bitset_stats.h (bitset_stats_enabled): Now bool, not int.
+	All uses changed.

+	* src/nullable.c (nullable_compute): Likewise.
+	* src/print.c (print_reductions): Likewise.
+	* src/tables.c (action_row, pack_vector): Likewise.
+	* src/muscle_tab.h (MUSCLE_INSERT_BOOL): New macro.
+	* src/output.c (prepare): Use it.
+	* src/output.c (token_definitions_output,
+	symbol_destructors_output, symbol_destructors_output): Use string,
+	not boolean integer, to keep track of whether to output separator.
+	* src/print_graph.c (print_core): Likewise.
+	* src/state.c (state_rule_lookaheads_print): Likewise.
+
+	* config/install-sh: Sync from automake 1.7.5.
+
+2003-05-14  Paul Eggert  <eggert@twinsun.com>
+
+	* src/parse-gram.y (rules_or_grammar_declaration): Require a
+	semicolon after a grammar declaration, in the interest of possible
+	future changes to the Bison input language.
+	Do not allow a stray semicolon at the start of the grammar.
+	(rhses.1): Allow one or more semicolons after any rule, including

+
+2003-05-14  Alexandre Duret-Lutz  <adl@gnu.org>
+
+	%parse-param support for lalr1.cc.
+
+	* data/lalr1.cc (b4_parse_param_decl, b4_parse_param_cons,
+	b4_cc_constructor_calls, b4_cc_constructor_call,
+	b4_parse_param_vars, b4_cc_var_decls, b4_cc_var_decl): New m4
+	definitions.
+	(yy::b4_parser_class_name::b4_parser_class_name): Take extra
+	parse-param arguments.
+	(yy::b4_parser_class_name): Declare instance variables to
+	hold parse-param arguments.
+	* tests/calc.at: s/value/semantic_value/ because value clashes
+	with a member of yy::b4_parser_class_name.  Adjust C++ code
+	to handle %parse-param.  Enable %parse-param test in C++.
+
+2003-05-12  Paul Eggert  <eggert@twinsun.com>
+
+	* doc/bison.texinfo (How Can I Reset @code{yyparse}): Reword the
+	English a bit.  Fix fclose typo.  Change "const char" to "char
+	const", and use ANSI C rather than K&R for "main".  Suggest
+	YY_FLUSH_BUFFER over yyrestart (as that is what Flex recommends)
+	and suggest yy_switch_to_buffer.
+
+2003-05-05  Paul Eggert  <eggert@twinsun.com>
+
+	* lib/bitset.h (__INT_TO_PTR): Define to a value that presumes
+	C89.  This avoids a diagnostic on compilers that define __STDC__
+	to 0, fixing a problem with Tru64 cc reported by Martin Mokrejs in
+	<http://mail.gnu.org/archive/html/bug-bison/2003-04/msg00041.html>.
+
+2003-05-03  Paul Eggert  <eggert@twinsun.com>

+	This should fix a bug reported today by Olatunji Oluwabukunmi in
+	<http://mail.gnu.org/archive/html/bug-bison/2003-05/msg00004.html>.
+
+2003-04-29  Akim Demaille  <akim@epita.fr>
+
+	* src/gram.h, src/gram.c (pure_parser, glr_parser): Move to...
+	* src/getargs.c, src/getargs.h: here, as bool, not int.
+	(nondeterministic_parser): New.
+	* src/parse-gram.y, src/scan-gram.l: Support
+	%nondeterministic-parser.
+	* src/output.c (prepare): Use nondeterministic_parser instead
+	of glr_parser where appropriate.
+	* src/tables.c (conflict_row, action_row, save_row)
+	(token_actions, token_actions, pack_vector): Ditto.
+
+2003-04-29  Akim Demaille  <akim@epita.fr>
+
+	* doc/bison.texinfo (C++ Parsers, Implementing Loops): New.
+
+2003-04-29  Akim Demaille  <akim@epita.fr>
+
+	* tests/calc.at: Also test yacc.c and glr.c (but not lalr1.cc yet)
+	with %pure-parser and %locations to exercise the patch from Yakov
+	Markovitch below.
+
+2003-04-28  Tim Van Holder <tim.van.holder@pandora.be>
+
+	* data/yacc.c: (b4_lex_param): Corrected for the case where
+	%lex-param is provided and %pure-parser isn't.
+
+2003-04-27  Paul Eggert  <eggert@twinsun.com>
+
+	Avoid gcc -Wundef warnings reported by Gerald Pfeifer in
+	<http://mail.gnu.org/archive/html/bug-bison/2003-04/msg00044.html>.
+	* data/yacc.c (YYSTACK_ALLOC): Don't evaluate YYSTACK_USE_ALLOCA
+	if it is not defined.
+	(YYMAXDEPTH): Don't evaluate YYMAXDEPTH if it is not defined.
+
+2003-04-26  Paul Eggert  <eggert@twinsun.com>
+
+	* data/lalr1.cc (yy::Parser::pact_ninf_, yy::Parser::table_ninf_):
+	Declare to be of type suitable for the ninf value itself, not of
+	type suitable for the corresponding table, since the latter might
+	be unsigned but the ninf value might be negative.  This fixes a
+	bug reported by Alexandre Duret-Lutz in
+	<http://mail.gnu.org/archive/html/bug-bison/2003-04/msg00017.html>.
+
+	* configure.ac (AC_FUNC_ERROR_AT_LINE): Remove, since gl_ERROR
+	invokes it.  We shouldn't invoke it twice because it will attempt
+	to put error.o in the archive twice.  This fixes a glitch reported
+	by Martin Mokrejs in
+	<http://mail.gnu.org/archive/html/bug-bison/2003-04/msg00041.html>.
+
+2003-04-21  Paul Eggert  <eggert@twinsun.com>
+
+	* m4/error.m4: Update from Bruno Haible's 2003-04-14 patch
+	to gnulib.
+
+2003-04-21  Yakov Markovitch <Markovitch@iso.ru>
+
+	* data/glr.c (yyexpandGLRStack) [!YYSTACKEXPANDABLE]:
+	Fix obvious typo that results in uncompilable GLR parsers
+	when both %pure-parser and %locations are used.  (trivial change)
+
+2003-04-17  Paul Eggert  <eggert@twinsun.com>
+
+	* src/scan-gram.l: Add %option nounput, since we no longer use unput.
+	(unexpected_eof): Renamed from unexpected_end_of_file, for brevity.
+	Do not insert the expected token via unput, as this runs afoul
+	of a POSIX-compatibility bug in flex 2.5.31.
+	All uses changed to BEGIN the parent state,
+	since we no longer insert the expected token via unput.
+	* tests/regression.at (Invalid inputs): Remove cascaded diagnostic
+	that is no longer emitted after the above change.
+
+	* src/conflicts.c (set_conflicts): Resolve all conflicts, not just
+	the first one.  This change is from Paul Hilfinger, and it fixes
+	regression reported by Werner Lemberg in
+	<http://mail.gnu.org/archive/html/bug-bison/2003-04/msg00026.html>.
+
+	(resolve_sr_conflict): Don't invoke state_errs_set
+	unless one or more tokens have been explicitly made errors.
+	Otherwise, the above change causes Bison to abort.
+
+	* tests/existing.at (GNU pic Grammar): New test case, taken from
+	Lemberg's email.
+
+2003-03-31  Akim Demaille  <akim@epita.fr>
+
+	* doc/Makefile.am (AM_MAKEINFOFLAGS): Don't split the info file.
+
+2003-03-31  Akim Demaille  <akim@epita.fr>
+
+	* src/output.c (prepare_symbols): Avoid trailing spaces in the
+	output.
+
+2003-03-31  Akim Demaille  <akim@epita.fr>
+
+	* doc/bison.texinfo (Strings are Destroyed): s/losses/loses/.
+	From Paul Hilfinger.
+
+2003-03-29  Akim Demaille  <akim@epita.fr>
+
+	* m4/error.m4: Do not put under dynamic conditions some code which
+	expansion is under static control.
+
+2003-03-29  Akim Demaille  <akim@epita.fr>
+
+	* doc/bison.texinfo (How Can I Reset @code{yyparse}): New.
+
+2003-03-29  Akim Demaille  <akim@epita.fr>
+
+	* doc/bison.texinfo (Strings are Destroyed): New.
+
+2003-03-13  Paul Eggert  <eggert@twinsun.com>
+
+	* .cvsignore: Add configure.lineno.
+	* src/.cvsignore: Add yacc.
+	* tests/.cvsignore: Add testsuite.log.
+	* doc/fdl.texi: Sync with latest FSF version.
+
+2003-03-12  Paul Eggert  <eggert@twinsun.com>
+
+	* scan-gram.l (YY_USER_INIT): Initialize code_start, too.
+	(<INITIAL><<EOF>>, <SC_PRE_CODE><<EOF>>): Set *loc to the scanner
+	cursor, instead of leaving it undefined.  This fixes a bug
+	reported by Tim Van Holder in
+	<http://mail.gnu.org/archive/html/bug-bison/2003-03/msg00023.html>.
+	* tests/input.at (Torturing the Scanner): Test the scanner on
+	an empty input file, which was Tim Van Holder's test case.
+
+	* m4/timevar.m4 (BISON_PREREQ_TIMEVAR): When checking whether
+	<sys/resource.h> can be included, include sys/time.h and
+	sys/times.h first, if available.  This works around the SunOS
+	4.1.4 porting bug reported by Bruce Becker in
+	<http://mail.gnu.org/archive/html/bug-bison/2003-03/msg00018.html>.
+
+	* m4/subpipe.m4 (BISON_PREREQ_SUBPIPE): Don't
+	AC_CHECK_HEADERS([sys/wait.h]), as this interferes with
+	AC_HEADER_SYS_WAIT.
+
+	Merge changes from gnulib.  This was prompted because the CVS
+	snapshot didn't build on Solaris 7 due to strnlen problems.
+
+	These changes need to be merged back into gnulib:
+	* lib/hash.c: Include <stdbool.h> unconditionally.
+	* m4/onceonly.m4 (m4_quote): New macro.
+	(AC_CHECK_HEADERS_ONCE, AC_CHECK_FUNCS_ONCE, AC_CHECK_DECLS_ONCE):

+	New files, imported from gnulib.
+	* m4/Makefile.am (EXTRA_DIST): Add the new m4/*.m4 files mentioned
+	above.
+
+	* lib/mbswidth.c, m4/error.m4, m4/mbrtowc.m4, m4/mbswidth.m4,

+	gnulib sources.
+
+	* configure.ac (gl_DIRNAME, gl_GETOPT, gl_HASH, gl_QUOTE, gl_XALLOC):
+	Add.
+	(gl_ERROR): New, replacing jm_PREREQ_ERROR.

+	(jm_PREREQ_ARGMATCH): Remove.
+	(AC_REPLACE_FUNCS): Remove memchr, memrchr, stpcpy, strtol, strtoul.
+	* lib/Makefile.am (libbison_a_SOURCES): Add argmatch.c, argmatch.h.
+
+	* src/system.h: Include <stdbool.h> unconditionally.
+
+	* lib/bbitset.h: Include <limits.h> unconditionally.  We have been
+	assuming at least C89 in the bitset code for some time now.
+
+2003-03-03  Akim Demaille  <akim@epita.fr>
+
+	* ro.po: New.
+
+2003-03-02  Akim Demaille  <akim@epita.fr>
+
+	* doc/bison.texinfo (Table of Symbols): Reactivate the
+	documentation for %lex-param, and %parse-param.
+
+2003-03-02  Akim Demaille  <akim@epita.fr>
+
+	* data/yacc.c, data/glr.c, data/lal1.cc: Use similar code to
+	generate verbose error messages.
+	Use the number of tokens as an upper bound in yytname, as it
+	cannot be a non terminal.
+
+2003-03-02  Akim Demaille  <akim@epita.fr>
+
+	* tests/regression.at (_AT_DATA_DANCER_Y): Fix the expected error
+	message.
+
+2003-03-02  Akim Demaille  <akim@epita.fr>
+
+	* tests/regression.at (_AT_DATA_DANCER_Y, AT_CHECK_DANCER): New.
+	Use them to exercise yycheck overrun.
+	Based on Andrew Suffield's grammar.
+
+2003-03-02  Akim Demaille  <akim@epita.fr>
+
+	Create tests/local.at for Bison generic testing macros.
+
+	* tests/calc.at (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): Move to...
+	* tests/local.at (AT_BISON_OPTION_PUSHDEFS, AT_BISON_OPTION_POPDEFS):
+	This new file.
+	* tests/calc.at (AT_CHECK_CALC): Adjust.
+	* tests/testsuite.at (AT_DATA_GRAMMAR_PROLOGUE, AT_DATA_GRAMMAR)

+2003-03-01  Paul Eggert  <eggert@twinsun.com>
+
+	* src/scan-gram.l (code_start): Initialize it to scanner_cursor,
+	not loc->end, since loc->end might contain garbage and this leads
+	to undefined behavior on some platforms.
+	(id_loc, token_start): Use (IF_LINTed) initial values that do not
+	depend on *loc, so that the reader doesn't give the the false
+	impression that *loc is initialized.
+	(<INITIAL>"%%"): Do not bother setting code_start, since its value
+	does not survive the return.
+
+2003-03-01  Akim Demaille  <akim@epita.fr>
+
+	* src/scan-gram.l (code_start): Always initialize it when entering
+	into yylex, as SC_EPILOGUE is activated *before* the corresponding
+	yylex invocation.  An alternative would be making it static, but
+	then it starts with the second %%'s beginning, instead of its end.
+
+2003-02-28  Paul Eggert  <eggert@twinsun.com>
+
+	* lib/mbswidth.c: Include <wchar.h> before "mbswidth.h", to work

+2003-02-24  Paul Eggert  <eggert@twinsun.com>
+
+	* data/glr.c (yy_reduce_print): yylineno -> yylno,

+	Suggested by Paul Eggert.
+
+2003-02-20  Akim Demaille  <akim@epita.fr>
+
+	* data/lalr1.cc (position.hh): Make sure "columns" never pushes
+	before initial_columns.
+	(location.hh): Use consistent variable names when defining the
+	operator<<.
+	Use "last" so that we subtract from Positions, not from unsigned.
+
+2003-02-20  Akim Demaille  <akim@epita.fr>
+
+	* data/lalr1.cc (position.hh): New subfile, including the extended
+	and Doxygen'ed documentation of class Position.
+	(location.hh): Use it.
+	Document a` la Doxygen.
+	With the help of Benoit Perrot.
+
+2003-02-20  Akim Demaille  <akim@epita.fr>
+
+	* tests/calc.at (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): Define
+	AT_YACC_IF.
+	Redefine AT_YYERROR_SEES_LOC_IF using it.
+	(_AT_DATA_CALC_Y): Don't declare yyerror when lalr1.cc, as it is
+	not defined.
+	Don't use the location in yy::Parser::error_ and
+	yy::Parser::print_ when not %locations.
+	Activate more lalr1.cc tests.
+
+2003-02-19  Akim Demaille  <akim@epita.fr>
+
+	* data/lalr1.cc: When displaying a line number, be sure to make it
+	an int.
+
+2003-02-19  Akim Demaille  <akim@epita.fr>
+

+	Disable the lalr1.cc tests as currently it doesn't support YYERROR.
+
+2003-02-17  Paul Eggert  <eggert@twinsun.com>
+
+	* tests/atlocal.in (LDFLAGS, LIBS): New vars.

+	Adjust the C locations to match those from Emacs: first column is
+	column 0.
+	Change all the expected results.
+	Conform to the GCS: simplify the locations when applicable.

+	<http://mail.gnu.org/archive/html/bug-bison/2003-01/msg00071.html>
+	and <http://mail.gnu.org/archive/html/bug-bison/2003-01/msg00073.html>.
+
+2003-01-21  Paul Eggert  <eggert@twinsun.com>
+
+	* data/yacc.c (YYERROR): Move code from yyerrlab1 to here, so that
+	we don't need to worry about yyerrlab1 being reported as an
+	"unused label" by non-GCC C compilers.  The downside is that if
+	locations are used then a couple of statements are duplicated each
+	time YYERROR is invoked, but the upside is that the warnings
+	should vanish.
+	(yyerrlab1): Move code to YERROR.
+	(yyerrlab2): Remove.  Change uses back to yyerrlab1.
+	This reverts some of the 2002-12-27 change.
+
+2003-01-17  Paul Eggert  <eggert@twinsun.com>
+
+	* src/output.c (symbol_printers_output): Fix typo that led
+	to core dump.  Problem reported by Antonio Rus in
+	<http://mail.gnu.org/archive/html/bug-bison/2003-01/msg00058.html>.
+
+2003-01-13  Akim Demaille  <akim@epita.fr>,
+		Quoc Peyrot <chojin@lrde.epita.fr>,
+		Robert Anisko <anisko_r@lrde.epita.fr>
+
+	* data/lalr1.cc (parse::yyerrlab1): When popping the stack, stop
+	when the stacks contain one element, as the loop would otherwise
+	free the last state, and then use the top state (the one we just
+	popped).  This means that the initial elements will not be freed
+	explicitly, as is the case in yacc.c; it is not a problem, as
+	these elements have fake values.
+
+2003-01-11  Paul Eggert  <eggert@twinsun.com>
+
+	* NEWS: %expect-violations are now just warnings, reverting
+	to Bison 1.30 and 1.75 behavior.  This fixes the GCC 3.2
+	bootstrapping problem reported by Matthias Klose; see
+	<http://mail.gnu.org/archive/html/bug-bison/2003-01/msg00053.html>.
+	* src/conflicts.c (conflicts_print): Likewise.
+	* tests/conflicts.at (%expect not enough, %expect too much,
+	%expect with reduce conflicts): Likewise.
+	* doc/bison.texinfo (Expect Decl): Document this.  Also mention
+	that the warning is enabled if the number of conflicts changes
+	(not necessarily increases).
+
+	* src/getargs.c (version): Update copyright year.
+
+2003-01-09  Akim Demaille  <akim@epita.fr>
+
+	* src/Makefile.am, lib/Makefile.am: Use $(VAR) instead of @VAR@.
+
+2003-01-08  Paul Eggert  <eggert@twinsun.com>
+
+	* Makefile.maint (WGETFLAGS):
+	New macro, containing "-C off" to disable proxy caches.
+	All uses of $(WGET) changed to $(WGET) $(WGETFLAGS).
+	(rel-check): Use $(WGET) instead of wget.
+
+2003-01-06  Paul Eggert  <eggert@twinsun.com>
+
+	* doc/bison.texinfo (Generalized LR Parsing): Add a reference to
+	the GLR paper of Scott, Johnstone and Hussain.
+
+2003-01-04  Paul Eggert  <eggert@twinsun.com>
+
+	* configure.ac (AC_ARG_ENABLE): Add --disable-yacc.
+	(YACC_SCRIPT, YACC_LIBRARY): New vars to AC_SUBST.
+	* lib/Makefile.am (lib_LIBRARIES): liby.a -> @YACC_LIBRARY@.
+	(EXTRA_LIBRARIES): New var, for liby.a.
+	* src/Makefile.am (bin_SCRIPTS): yacc -> @YACC_SCRIPT@.
+	(EXTRA_SCRIPTS): New var, for yacc.
+
+	* data/yacc.c (yyerrlab1): Omit attribute if __cplusplus is defined,
+	since GNU C++ (as of 3.2.1) does not allow attributes on labels.
+	Problem reported by Nelson H. F. Beebe.
+
+2003-01-03  Paul Eggert  <eggert@twinsun.com>
+
+	* lib/obstack.h (__INT_TO_PTR) [__STDC__]: Cast result to
+	(void *) to avoid diagnostic with native c89 on SGI IRIX 6.5
+	when compiling Bison 1.875's `bitset bset = obstack_alloc
+	(bobstack, bytes);'.  Problem reported by Nelson H. F. Beebe.
+
+	* src/scan-skel.l (QPUTS): Omit redundant `;' from macro definition.
+	([^@\n]): Renamed from [^@\n]+ so that the token buffer does not
+	grow to a huge size with typical invocation.
+
+	* lib/hash.c (_Bool, bool, false, true, __bool_true_false_are_defined):
+	Use the pattern recommended by Autoconf 2.57, except also protect
+	against double-definition.
+	* src/system.h: Likewise.
+	Portability issues reported by Nelson H. F. Beebe.
+
+	* data/glr.c (yybool): Renamed from bool, to avoid collisions in C.
+	All uses changed.  Provide a definition in both C and C++.
+	(yytrue, yyfalse): Define even if defined (__cplusplus).
+
+	* lib/bitset_stats.c (bitset_stats_list): Remove unused var.
+	Reported by Nelson H. F. Beebe.
+
+	* src/scan-skel.l ("@oline@"): Output lineno+1, not lineno.
+
+2003-01-02  Paul Eggert  <eggert@twinsun.com>
+
+	* data/yacc.c (yyerrlab1): Append `;' after attribute, to
+	pacify the buggy "smart preprocessor" in MacOS 10.2.3.
+	Bug reported by Nelson H. F. Beebe.
+
+2003-01-01  Paul Eggert  <eggert@twinsun.com>
+
+	* Version 1.875.
+
+2002-12-30  Paul Eggert  <eggert@twinsun.com>
+
+	* src/scan-gram.l (<INITIAL,SC_AFTER_IDENTIFIER,SC_PRE_CODE>","):
+	Moved here from...
+	(<INITIAL>","): Here.  This causes stray "," to be treated
+	more uniformly.
+
+	* src/scan-gram.l (<SC_BRACED_CODE>"}"): Output ";" before the
+	last brace in braced code when not in Yacc mode, for compatibility
+	with Bison 1.35.  This resurrects the 2001-12-15 patch to
+	src/reader.c.
+
+	* src/reader.h (YYDECL): Use YYSTYPE, not its deprecated alias
+	yystype.  This follows up the 2002-12-24 YYSTYPE bug fix.
+
+2002-12-28  Paul Eggert  <eggert@twinsun.com>
+
+	* src/symtab.c (symbol_make_alias): Set type of SYMVAL to be
+	that of SYM's type.  This fixes Debian bug 168069, reported by
+	Thomas Olsson.
+
+2002-12-28  Paul Eggert  <eggert@twinsun.com>
+
+	Version 1.75f.
+
+	Switch back to the Yacc style of conflict reports, undoing some
+	of the 2002-07-30 change.
+	* doc/bison.texinfo (Understanding): Use Yacc style for
+	conflict reports.  Also, use new way of locating rules.
+	* src/conflicts.c (conflict_report):
+	Renamed from conflict_report_yacc, removing the old
+	'conflict_report'.  Translate the entire conflict report at once,
+	so that we don't assume that "," has the same interpretation in
+	all languages.
+	(conflicts_output): Use Yacc-style conflict report for each state,
+	instead of our more-complicated style.
+	(conflicts_print): Use Yacc-style conflict report, except print
+	the input file name when not emulating Yacc.
+	* tests/conflicts.at (Unresolved SR Conflicts, Defaulted
+	Conflicted Reduction, %expect not enough, %expect too much,
+	%expect with reduce conflicts): Switch to Yacc-style conflict reports.
+	* tests/existing.at (GNU Cim Grammar): Likewise.
+	* tests/glr-regr1.at (Badly Collapsed GLR States): Likewise.
+
+	* src/complain.c (warn_at, warn, complain_at, complain, fatal_at,
+	fatal): Don't invoke fflush; it's not needed and it might even be
+	harmful for stdout, as stdout might not be open.
+	* src/reduce.c (reduce_print): Likewise.
+
+2002-12-27  Paul Eggert  <eggert@twinsun.com>
+
+	Fix a bug where error locations were not being recorded correctly.
+	This problem was originally reported by Paul Hilfinger in
+	<http://mail.gnu.org/archive/html/bug-bison/2002-11/msg00086.html>.
+
+	* data/yacc.c (yyparse): New local var yylerrsp, to record the
+	top of the location stack's error locations.
+	(yyerrlab): Set it.  When discarding a token, push its location
+	onto yylerrsp so that we don't lose track of the error's end.
+	(yyerrlab1): Now is only the target of YYERROR, so that we can
+	properly record the location of the action that failed.  For GCC
+	2.93 and later, insert an __attribute__ ((__unused__)) to avoid
+	GCC warning about yyerrlab1 being unused if YYERROR is unused.
+	(yyerrlab2): New label, which yyerrlab now falls through to.
+	Compute the error's location by applying YYLLOC_DEFAULT to
+	the locations of all the symbols that went into the error.
+	* doc/bison.texinfo (Location Default Action): Mention that
+	YYLLOC_DEFAULT is also invoked for syntax errors.
+	* tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
+	Error locations include the locations of all the tokens that were
+	discarded, not just the last token.
+
+2002-12-26  Paul Eggert  <eggert@twinsun.com>
+
+	* src/files.c: Include quote.h.
+	(compute_output_file_names): Warn if we detect conflicting
+	outputs to the same file.  This should catch the misunderstanding
+	exemplified by Debian Bug 165349, reported by Bruce Stephens..
+
+	* src/conflicts.c (conflicts_print): If the user specifies
+	"%expect N", report an error if there are any reduce/reduce
+	conflicts.  This is what the manual says should happen.
+	This fixes Debian bug 130890, reported by Anthony DeRobertis.
+	* tests/conflicts.at (%expect with reduce conflicts): New test.
+
+	Don't use m4_include on relative file names, as it doesn't work as
+	desired if there happens to be a file with that name under ".".
+
+	* m4sugar/version.m4: Remove; it was included but it wasn't used.
+	* data/Makefile.am (dist_m4sugar_DATA): Remove m4sugar/version.m4.
+	* data/m4sugar/m4sugar.m4: Don't include m4sugar/version.m4.
+	* data/glr.c, data/lalr1.cc, data/yacc.c: Don't include c.m4.
+	* src/output.c (output_skeleton): Use full path names when
+	specifying a file to include; don't rely on include path, as
+	it's unreliable when the working file contains a file with
+	that name.
+
+2002-12-25  Paul Eggert  <eggert@twinsun.com>
+
+	Remove obsolete references to bison.simple and bison.hairy.
+	Problem mentioned by Aubin Mahe in
+	<http://mail.gnu.org/archive/html/help-bison/2002-12/msg00010.html>.
+	* data/glr.c: Comment fix.
+	* doc/bison.1: Remove references.  Also, mention "yacc".
+
+	* src/getargs.c (getargs) [MSDOS]: Don't assume optarg != NULL
+	with -g option.
+
+	* src/parse-gram.y (declaration): Use enum "report_states" rather
+	than its numeric value 1.
+
+	* src/scan-skel.l ("@output ".*\n): Close any old yyout before
+	opening a new one.  This fixes Debian bug 165349, reported by
+	Bruce Stephens.
+
+2002-12-24  Paul Eggert  <eggert@twinsun.com>
+
+	Version 1.75e.
+
+	* Makefile.maint (cvs-update): Don't assume that the shell
+	supports $(...), as Solaris sh doesn't.
+
+	* src/parse-gram.y (lloc_default): Remove test for empty
+	nonterminals at the end, since it didn't change the result.
+
+2002-12-24  Paul Eggert  <eggert@twinsun.com>
+
+	If the user does not define YYSTYPE as a macro, Bison now declares it
+	using typedef instead of defining it as a macro.  POSIX requires this.
+	For consistency, YYLTYPE is also declared instead of defined.
+
+	%union directives can now have a tag before the `{', e.g., the
+	directive `%union foo {...}' now generates the C code
+	`typedef union foo { ... } YYSTYPE;'; this is for Yacc compatibility.
+	The default union tag is `YYSTYPE', for compatibility with Solaris 9
+	Yacc.  For consistency, YYLTYPE's struct tag is now `YYLTYPE'
+	instead of `yyltype'.
+
+	`yystype' and `yyltype' are now obsolescent macros instead of being
+	typedefs or tags; they are no longer documented and will be
+	withdrawn in a future release.
+
+	* data/glr.c (b4_location_type): Remove.
+	(YYSTYPE): Renamed from yystype.
+	(YYSTYPE_IS_DECLARED): New macro, used to prevent double-typedef.
+	(struct YYLTYPE): Renamed from struct yyltype.
+	(YYLTYPE): Renamed from yyltype.
+	(yyltype, yystype): New (and obsolescent) macros,
+	for backward compatibility.
+	* data/yacc.c: Likewise.
+
+	* data/yacc.c (YYSTYPE): Declare as union YYSTYPE if the user
+	does not specify a union tag.  This is for compatibility with
+	Solaris 9 yacc.
+
+	* src/parse-gram.y (add_param): 2nd arg is now char * not char
+	const *, since it is now modified by stripping surrounding { }.
+	(current_braced_code): Remove.
+	(PERCENT_DESTRUCTOR, PERCENT_PRINTER, PERCENT_UNION,
+	PERCENT_LEX_PARAM, PERCENT_PARSE_PARAM): Change names to include
+	trailing " {...}".  Now of type <chars>.
+	(grammar_declaration): Adjust to bundled tokens.
+	(code_content): Remove; stripping is now done by add_param.
+	(print_token_value): Print contents of bundled tokens.
+	(token_name): New function.
+
+	* src/reader.h (braced_code, current_braced_code): Remove.
+	(token_name): New decl.
+
+	* src/scan-gram.l (handle_dollar, handle_at): Now takes int
+	token_type, not braced_code code_kind.  All uses changed.
+	(SC_PRE_CODE): New state, for scanning after a keyword that
+	has (or usually has) an immediately-following braced code.
+	(token_type): New local var, to keep track of which token type
+	to return when scanning braced code.
+	(<INITIAL>"%destructor", <INITIAL>"%lex-param",
+	<INITIAL>"%parse-param", <INITIAL>"%printer",
+	<INITIAL>"%union"): Set token type and BEGIN SC_PRE_CODE
+	instead of returning a token type immediately.
+	(<INITIAL>"{"): Set token type.
+	(<SC_BRACED_CODE>"}"): Use it.
+	(handle_action_dollar, handle_action_at): Now returns bool
+	indicating success.  Fail if ! current_rule; this prevents a core dump.
+	(handle_symbol_code_dollar, handle_symbol_code_at):
+	Remove; merge body into caller.
+	(handle_dollar, handle_at): Complain in invalid contexts.
+
+	* NEWS, doc/bison.texinfo: Document the above.
+	* NEWS: Fix years and program names in copyright notice.
+
+2002-12-17  Paul Eggert  <eggert@twinsun.com>
+
+	* NEWS, doc/bison.texinfo (Parser Function, Pure Calling, Error
+	Reporting, Table of Symbols): Omit mentions of %lex-param and
+	%parse-param from the documentation for now.
+
+2002-12-15  Paul Eggert  <eggert@twinsun.com>
+
+	Undo most of the 2002-11-12 yychar -> yytoken patch, as it broke
+	GCC 3.2.1 (which depends on yychar == YYEMPTY when there is no
+	lookahead symbol, and which sets yychar in parser actions) and it
+	disagreed with the Bison documentation.  Bug
+	reported by Andrew Walrond.
+
+	* data/yacc.c (YYTRANSLATE): Don't check for negative argument,
+	as the caller now does that.
+	(yyclearin, YYBACKUP, yyparse): Use yychar, not yytoken.
+	(YYEMPTY): Parenthesize right hand side, since others use it.
+	(yyparse): Don't assume that our generated code is the only code
+	that sets yychar.
+
+2002-12-13  Paul Eggert  <eggert@twinsun.com>
+
+	Version 1.75d.
+
+	POSIX requires a "yacc" command.
+	* src/Makefile.am (bin_SCRIPTS): New macro, for yacc.
+	(MOSTLYCLEANFILES): Add yacc.
+	(yacc): New rule.
+	* doc/bison.texinfo (Invocation, Bison Options): Mention yacc
+	as an alias for bison y.
+
+	* po/LINGUAS: Add da.
+
+	* src/getargs.c (__GNU_LIBRARY__) [lint]: Define to work around
+	problem with latest <getopt.h>.
+	(HACK_FOR___GNU_LIBRARY___PROTOTYPE): New macro.
+
+	* doc/fdl.texi: Upgrade to 1.2.
+	* lib/alloca.c, lib/error.c, lib/getopt.c, lib/getopt.h
+	lib/getopt1.c, lib/gettext.h, lib/memrchr.c, lib/obstack.c,
+	lib/obstack.h, lib/strnlen.c, lib/unlocked-io.h: Sync with

+	* config/install-sh: Sync with autotools.
+
+	Fix a bad interaction with flex 2.5.23 reported by Bruce Lilly in
+	<http://mail.gnu.org/archive/html/bug-bison/2002-11/msg00114.html>.
+	* data/yacc.c (YYLTYPE, struct yyltype): Do not define unless
+	locations are requested.
+	(union yyalloc): Do not depend on YYLTYPE_IS_TRIVIAL unless
+	locations are requested.
+
+2002-12-12  Paul Eggert  <eggert@twinsun.com>
+
+	Remove unportable casts and storage allocation tricks.
+	While we're at it, remove almost all casts, since they
+	usually aren't needed and are a sign of trouble.
+
+	* configure.ac (AC_CHECK_TYPES): Check for uintptr_t.
+
+	* src/derives.c (derives_compute): Do not subtract NTOKENS from
+	the pointer DSET returned by malloc; this isn't portable.
+	Instead, always use DSET[i - NTOKENS] rather than DSET[i].
+	Similarly for DERIVES.
+	* src/lalr.c (set_goto_map): Likewise, for GOTO_MAP and TEMP_MAP.
+	* src/nullable.c (nullable_compute): Likewise, for RSETS and NULLABLE.
+	* src/reduce.c (reduce_grammar_tables): Likewise, for nontermmap
+
+	* src/derives.c (derives_compute): Do not bother invoking
+	int_of_rule_number, since rule numbers are integers.
+
+	* src/files.c (concat2, tr, compute_base_name): Use xmalloc (N)
+	rather than XMALLOC (char, N).
+
+	* src/files.c (filename_split): Rewrite to avoid cast.
+
+	* src/gram.h (symbol_number_as_item_number,
+	item_number_as_symbol_number, rule_number_as_item_number,

+
+	* src/gram.h (int_of_rule_number): Remove; no longer used.
+
+	* src/lalr.c (add_lookback_edge): Use malloc rather than calloc,
+	since the resulting storage is always stored into.
+
+	* src/main.c (alloca) [C_ALLOCA]: Add decl here, the only place
+	where it's needed.
+
+	* src/muscle_tab.c (muscle_m4_output):
+	Now inline.  Return bool, not int.
+	* src/state.c (state_compare): Likewise.

+
+	* src/output.c (GENERATE_MUSCLE_INSERT_TABLE): Use long local
+	var instead of casting to long, to avoid casts.
+	(prepare_states): Use MALLOC rather than alloca, so that we don't
+	have to worry about alloca.
+	* src/state.c (state_hash_lookup): Likewise.
+
+	* src/scan-gram.l (<SC_ESCAPED_CHARACTER>"'"): Use unsigned char
+	local var instead of casting to unsigned char, to avoid casts.
+
+	* src/state.c (TRANSITIONS_ALLOC, ERRS_ALLOC, REDUCTIONS_ALLOC,
+	STATE_ALLOC): Remove.
+	(transitions_new, errs_new, reductions_new, state_new): Use malloc
+	rather than calloc, and use offsetof to avoid allocating slightly
+	too much storage.
+	(state_new): Initialize all members.
+

+
+	* src/symtab.c (symbol_free): Remove; unused.

+	(uintptr_t): New type, if system lacks it.
+	(CALLOC, MALLOC, REALLOC): New macros.
+	All uses of XCALLOC, XMALLOC, and XREALLOC changed to use these

+
+2002-12-09  Paul Eggert  <eggert@twinsun.com>
+
+	Change identifier spellings to avoid collisions with names
+	that are reserved by POSIX.
+
+	Don't use names ending in _t, since POSIX reserves them.
+	For consistency, remove _e and _s endings -- they're weren't

+
+	* data/glr.c, data/lalr1.cc, data/yacc.c: Do not use __file__,
+	since this causes problems when __file__ contains character
+	sequences like "@" that are treated specially by src/scan-skel.l.
+	Instead, just use the file's basename.  This fixes the bug

+	<http://mail.gnu.org/archive/html/bug-bison/2002-12/msg00007.html>.
+
+2002-12-06  Paul Eggert  <eggert@twinsun.com>
+
+	Add support for rules that do not have trailing semicolons, as

+	GNU Coding Standards for locations that span file boundaries.
+	* src/location.h: Do not include <quotearg.h>; no longer needed.
+	(boundary): New type.
+	(location_t): Use it.  This allows locations to span file boundaries.

+	last_line -> end.line, last_column -> end.column.
+	(equal_boundaries): New function.

+	(STEP): Remove.  No longer needed, now that adjust_location does
+	the work.  All uses removed.

+	(id_loc, code_start, token_start): New local vars.
+	(<INITIAL,SC_AFTER_IDENTIFIER>): New initial context.  Move all
+	processing of Yacc white space and equivalents here.
+	(<INITIAL>{id}): Save id_loc.  Begin state SC_AFTER_IDENTIFIER
+	instead of returning ID immediately, since we need to search for
+	a subsequent colon.
+	(<INITIAL>"'", "\""): Save token_start.
+	(<INITIAL>"%{", "{", "%%"): Save code_start.

+
+	* src/complain.h (current_file): Remove duplicate decl;
+	current_file is now owned by files.h.
+	* src/complain.c, src/scan-gram.l: Include files.h.
+
+2002-12-06  Paul Eggert  <eggert@twinsun.com>
+
+	* data/glr.c (yy_reduce_print): Don't assume that yyrline[yyrule]
+	promotes to int; it might be unsigned int.
+	* data/yacc.c (yy_reduce_print): Likewise.
+
+	* doc/bison.texinfo (Table of Symbols): YYERROR_VERBOSE should
+	be #defined in the prologue, not in the Bison declarations.
+	This fixes Debian Bug 102878, reported by Shaul Karl.
+
+2002-12-02  Paul Eggert  <eggert@twinsun.com>
+
+	* configure.ac (AC_REPLACE_FUNCS): Add strtoul.
+	* lib/strtoul.c: New file, from gnulib.
+	This fixes a porting bug reported by Peter Klein in

+
+2002-11-30  Paul Eggert  <eggert@twinsun.com>
+
+	* src/scan-gram.l (no_cr_read, extend_location): Move to epilogue,
+	and put only a forward declaration in the prologue.  This is for
+	consistency with the other scanner helper functions.
+
+	Type clashes now generate warnings, not errors, since it
+	appears that POSIX may allow some grammars with type clashes.
+	* src/reader.c (grammar_current_rule_check): Warn about
+	type clashes instead of complaining.
+	* tests/input.at (Type Clashes): Expect warnings, not complaints.
+
+	Add Yacc library, since POSIX requires it.
+	* doc/bison.texinfo (Yacc Library): New node.  Regenerate top menu.
+	* lib/Makefile.am (lib_LIBRARIES, liby_a_SOURCES): New macros.
+	* lib/main.c, lib/yyerror.c: New files.
+
+	gram_error can be static; it need not be extern.
+	* src/reader.h (gram_error): Remove decl.
+	* src/parse-gram.y (gram_error): Now static.  Add static decl.
+	(print_token_value): Omit parameter names from forward decl,
+	for consistency.
+
+2002-11-29  Paul Eggert  <eggert@twinsun.com>
+
+	* doc/bison.texinfo: Emphasize that yylex and yyerror must
+	be declared before being used.  E.g., one should typically
+	declare them in the prologue.  Use GNU coding style in examples.
+	Put "const" consistently after the type it modifies.  Mention
+	that C99 supports "inline".  Mention that yyerror traditionally
+	returns "int".
+
+	%parse-param and %lex-param now take just one argument, the
+	declaration; the argument name is deduced from the declaration.
+
+	* doc/bison.texinfo (Parser Function, Pure Calling, Error
+	Reporting, Table of Symbols): Document this.
+	* src/parse-gram.y (add_param): New function.
+	(COMMA): Remove.
+	(declaration): Implement new rule for %parse-param and %lex-param.
+	* src/scan-gram.l: "," now elicits a warning, rather than being
+	a token; this is more compatible with byacc.
+	* tests/calc.at (Simple LALR Calculator): Adopt new convention.
+
+2002-11-27  Paul Eggert  <eggert@twinsun.com>
+
+	Rename identifiers to avoid real and potential collisions.
+
+	* data/c.m4 (b4_yysymprint_generate): yyout -> yyoutput,

+	* src/parse-gram.y (print_token_value): Renamed from yyprint.
+	All uses changed.
+	(YYPARSE_PARAM, YYLEX_PARAM, yycontrol): Remove.  All uses changed.
+	The name "yycontrol" violates the name space rules, and this stuff
+	wasn't being used anyway.
+	(input): Remove action; this stuff wasn't being used.
+	(gram_error): Rename local variable yylloc -> loc.
+	* src/reader.h (struct gram_control_s, gram_control_t): Remove.
+	(YY_DECL): Don't use "yy" at start of local variables.
+	All uses changed, e.g., yylloc -> loc.
+	* src/scan-gram.l (STEP): Renamed from YY_STEP.  All uses changed.
+	(STRING_GROW): Renamed from YY_OBS_GROW.  All uses changed.
+	(STRING_FINISH): Renamed from YY_OBS_FINISH.  All uses changed.

+
+2002-11-24  Paul Eggert  <eggert@twinsun.com>
+
+	Version 1.75c.
+
+	* tests/actions.at (Actions after errors): Use an output format
+	more similar to that of the Printers and Destructors test.
+	Test the position of the ';' token too.
+	(Printers and Destructors): Likewise.
+	(Printers and Destructors: %glr-parser): Remove for now, to avoid
+	unnecessarily alarming people when the test fails.
+
+	* data/yacc.c (yyerrlab1): Move this label down, so that the
+	parser does not discard the lookahead token if the user code
+	invokes YYERROR.  This change is required for POSIX conformance.
+
+	* lib/error.c: Sync with gnulib.
+
+2002-11-22  Paul Eggert  <eggert@twinsun.com>

+
+	Avoid use of <assert.h>, as the GNU Coding Standards hint that one

+
+	* data/glr.c (yygetLRActions): Replace `yyindex' with

+
+2002-11-18  Akim Demaille  <akim@epita.fr>

+2002-11-17  Paul Eggert  <eggert@twinsun.com>
+
+	Pacify Sun ONE Studio 7 lint.  Also, rename "ParseError"

+
+	* data/glr.c (YYDPRINTF, YYDSYMPRINT, YYDSYMPRINTF) [!YYDEBUG]: Do

+
+2002-11-16  Akim Demaille  <akim@epita.fr>
+
+	Make the ``Printers and Destructors'' test more verbose, taking

+	* src/output.c (output_skeleton): Call xfopen instead of
+	duplicating xfopen's body.
+
+	Fix bugs reported by Nelson H. F. Beebe in
+	<http://mail.gnu.org/archive/html/bug-bison/2002-11/msg00078.html>.
+
+	* tests/headers.at (AT_TEST_CPP_GUARD_H): Don't assume that
+	"$CC -E foo.h" is allowed, as this doesn't work with the Portland
+	Group compiler.  Instead, use "$CC -E bar.c".  Include the .h
+	file twice in the grammar, as an extra check.
+
+	* tests/input.at (Torturing the Scanner): Surround the
+	backslash-newline tests with "#if 0", to make it less likely that
+	we'll run into compiler bugs.  Bring back solitary \ inside
+	comment, but add a closing comment to work around HP C bug.  Don't
+	test backslash-newline in C character constant.

+2002-11-14  Akim Demaille  <akim@epita.fr>
+

+
+2002-11-14  Akim Demaille  <akim@epita.fr>
+

+
+2002-11-13  Paul Eggert  <eggert@twinsun.com>
+
+	Fix some bugs reported by Albert Chin-A-Young in
+	<http://mail.gnu.org/archive/html/bug-bison/2002-11/msg00066.html>.
+

+	-o c"; the HP C compiler chatters during compilation.
+	Instead, invoke "cc -c a.c -o a.o; cc -c b.c -o b.o; cc a.o b.o -o c".
+	* tests/headers.at (export YYLTYPE): Likewise.
+
+	* tests/input.at (Torturing the Scanner): Remove lines containing
+	solitary backslashes, as they tickle a bug in the HP C compiler.
+
+	* tests/glr-regr1.at (Badly Collapsed GLR States): Avoid //
+	comments, since they're not portable.  Use GNU coding style.
+
+2002-11-13  Akim Demaille  <akim@epita.fr>

+	Use it.
+
+2002-11-12  Paul Eggert  <eggert@twinsun.com>
+
+	Version 1.75b.
+
+	* data/glr.c (yydoAction): Return YYRESULTTAG, not int.
+	(yyglrReduce): Return yyok, not 0.
+	This should avoid the enumerated-type warnings reported
+	by Nelson H. F. Beebe in
+	<http://mail.gnu.org/archive/html/bug-bison/2002-11/msg00057.html>.
+
+	* lib/bbitset.h (BITSET_INLINE): Remove.

+	(bitset_set, bitset_reset, bitset_test): Rename local vars
+	to avoid shadowing warnings by GCC.
+
+	* data/glr.c (inline): Remove #define.  It's the user's
+	responsibility to #define it away, just like 'const'.
+	This fixes one of the bugs reported by Nelson H. F. Beebe in
+	<http://mail.gnu.org/archive/html/bug-bison/2002-11/msg00058.html>.
+
+	* Makefile.maint (po-check): Scan .l and .y files instead of the
+	.c and the .h files that they generate.  This fixes the bug
+	reported by Tim Van Holder in:
+	<http://mail.gnu.org/archive/html/bison-patches/2002-11/msg00062.html>
+	Look for N_ as well as for _.  Try to avoid matching #define for
+	N_ and _.
+	* po/POTFILES.in: Remove src/parse-gram.c, src/scan-gram.c,
+	src/system.h.  Add src/parse-gram.y, src/scan-gram.l.
+	* src/scan-gram.l: Revamp regular expressions so that " and '
+	do not confuse xgettext.
+
+	* src/struniq.h (struniq_new): Do not declare the return type
+	to be 'const'; this violates the C standard.

+
+2002-11-12  Akim Demaille  <akim@epita.fr>

+	Accept pointers as arguments, as opposed to the version from
+	yacc.c.
+	(b4_yydestruct_generate): Likewise.
+	* tests/cations.at (Printers and Destructors): Use Bison directives

+
+	* data/c.m4 (b4_yydestruct_generate, b4_symbol_actions): New.
+	* data/yacc.c: Rename yychar1 as yytoken, as in glr.c.
+	Don't work on yychar (i.e., do set it to YYEMPTY, don't match

+	it to YYEMPTY etc.).
+	(yydestruct): Replace with a b4_yydestruct_generate invocation.
+	(b4_symbol_actions): Remove.
+	* data/glr.c (YYTRANSLATE): As for yacc.c, if negative, it stands
+	for 0, end-of-input.

+

+
+2002-11-11  Paul Eggert  <eggert@twinsun.com>
+
+	Revamp to fix many (but not all) of the C- and M4-related quoting
+	problems.  Among other things, this fixes the Bison bug reported
+	by Jan Hubicka when processing the Bash grammar; see:
+	<http://mail.gnu.org/archive/html/bison-patches/2002-11/msg00039.html>
+
+	Use new @ escapes consistently.  Represent brackets with @{ and @}
+	rather than @<:@ and @:>@, since this works a bit better with dumb
+	editors like vi.  Represent @ with @@, since @ is now consistently
+	an escape.  Use @oline@ and @ofile@ rather than __oline__ and
+	__ofile__, to avoid unexpected expansions.  Similarly, use @output
+	rather than #output.
+
+	* data/c.m4 (b4_copyright): Omit file name from comment, since
+	the file name could contain "*/".
+	(b4_synclines_flag): Don't quote the 2nd argument; it should already
+	be quoted.  All uses changed.
+
+	* data/glr.c: Use new @ escapes consistently.
+	(b4_input_suffix, b4_output_parser_suffix, b4_output_parser_name,
+	b4_output_header_suffix, b4_output_header_name, b4_header_guard):
+	Remove, since they couldn't handle arbitrary characters in file
+	names.
+	* data/lalr1.cc: Likewise.
+	* data/yacc.c: Likewise.
+
+	* src/files.c (output_infix): Remove; all uses removed.
+	* src/files.h: Likewise.
+
+	* data/glr.c: Remove use of "#ifdef b4_header_guard", since it
+	mishandled funny characters in file names, and anyway it isn't
+	needed any more.
+	* data/yacc.c: Likewise.
+	* data/lalr1.cc: Use YYSLP_NEEDED instead of b4_header_guard.
+
+	* data/glr.c (YYSTYPE_IS_TRIVIAL): Define when the .h file would.
+	* data/yacc.c: Likewise.
+
+	* src/muscle_tab.c: Include quotearg.h, since we need to quote C
+	strings now.
+	(muscle_init): Quote filename as a C string.
+	* src/muscle_tab.h (MUSCLE_GROW_STRING_PAIR): Remove; unused.
+	(MUSCLE_OBSTACK_SGROW, MUSCLE_INSERT_C_STRING): New macros.
+	* src/output.c (escaped_file_name_output): New function.
+	(prepare_symbols): Quote tokens for M4.
+	(prepare): Don't insert output_infix, output_prefix,
+	output_parser_name, output_header_name; this is now down by scan-skel.
+	Insert skeleton as a C string.
+
+	* src/output.c (user_actions_output, symbol_destructors_output,
+	symbol_printers_output): Quote filenames for C and M4.
+	* src/reader.c (prologue_augment, epilogue_set): Likewise.
+
+	* src/scan-gram.l (<SC_CHARACTER>): Don't worry about any backslash
+	escapes other than \\ and \'; this simplifies the code.
+	(<SC_STRING>): Likewise, for \\ and \".
+	(<SC_COMMENT,SC_LINE_COMMENT,SC_STRING,SC_CHARACTER,SC_BRACED_CODE,
+	SC_PROLOGUE,SC_EPILOGUE>): Escape $ and @, too.
+	Use new escapes @{ and @} for [ and ].
+
+	* src/scan-skel.l (yylineno, yyoutname): Remove static vars, replacing
+	them with auto vars.
+	Switch to new escape scheme, where @ is the escape character uniformly.
+	Abort if a stray escape character is found.  Avoid unbounded input
+	buffer when parsing non-escaped text.
+
+	* tests/input.at (Torturing the Scanner): Add tests that @oline@,
+	__oline__, #output, $@, and @{ do not have unintended meanings.
+
+2002-11-09  Paul Eggert  <eggert@twinsun.com>
+
+	Fix the test failure due to GCC warnings described in
+	<http://mail.gnu.org/archive/html/bug-bison/2002-11/msg00000.html>.
+	* data/glr.c (yyis_pact_ninf, yyis_table_ninf): New macros, which
+	evaluate to 0 if it's impossible for NINF to be in the respective
+	table.
+	(yygetLRActions, yyrecoverParseError): Use them.
+
+	* src/scan-gram.l (unexpected_end_of_file): Fix bug: columns were
+	counted in the token inserted at end of file.  Now takes
+	location_t *, not location_t, so that the location can be
+	adjusted.  All uses changed.
+
+	* tests/regression.at (Invalid inputs): Adjust wording in
+	diagnostic to match the new behavior.
+
+	* tests/torture.at (AT_DATA_TRIANGULAR_GRAMMAR,
+	AT_DATA_HORIZONTAL_GRAMMAR, AT_DATA_LOOKAHEADS_GRAMMAR,
+	AT_DATA_STACK_TORTURE): Replace `assert (x);' with `if (! (x))
+	abort ();'.  This reduces the runtime of the "Many lookaheads"
+	test from 27.6 to 2.7 minutes on a 440 MHz Ultrasparc III running
+	GCC 3.2.
+
+2002-11-07  Paul Eggert  <eggert@twinsun.com>
+
+	* src/parse-gram.y (CHARACTER): Remove unused token.
+	All uses removed.
+
+	* src/scan-gram.l: Remove stack option.  We no longer use the
+	stack, since the stack was never deeper than 1; instead, use the
+	new auto var c_context to record the stacked value.
+
+	Remove nounput option.  At an unexpected end of file, we now unput
+	the minimal input necessary to end cleanly; this simplifies the
+	code.
+
+	Avoid unbounded token sizes where this is easy.
+
+	(unexpected_end_of_file): New function.
+	Use it to systematize the error message on unexpected EOF.
+	(last-string): Now auto, not static.
+	(YY_OBS_FREE): Remove unnecessary do while (0) wrapper.
+	(scanner_last_string_free): Remove; not used.
+	(percent_percent_count): Move decl to just before use.
+	(SC_ESCAPED_CHARACTER): Return ID at unexpected end of file,
+	not the (never otherwised-used) CHARACTER.

+	* tests/input.at (Invalid $n, Invalid @n): Change expected wording
+	accordingly.
+
+	Scan <% and %> digraphs in C code as POSIX 1003.1-2001 requires.
+	Also, remove one static variable in the scanner.
+
+	* src/scan-gram.l (braces_level): Now auto, not static.
+	Initialize to zero if the compiler is being picky.

+
+2002-11-03  Paul Eggert  <eggert@twinsun.com>
+
+	* src/scan-gram.l: Revamp to fix POSIX incompatibilities,

+
+	Use mbsnwidth to count columns correctly.  Account for tabs, too.
+	Include mbswidth.h.
+	(YY_USER_ACTION): Invoke extend_location rather than LOCATION_COLUMNS.
+	(extend_location): New function.

+	(SC_LINE_COMMENT, SC_YACC_COMMENT): New states.
+	(eols, blanks): Remove.  YY_USER_ACTION now counts newlines etc.;
+	all uses changed.
+	(tag, splice): New EREs.  Do not allow NUL or newline in tags.
+	Use {splice} wherever C allows backslash-newline.
+	YY_STEP after space, newline, vertical-tab.
+	("/*"): BEGIN SC_YACC_COMMENT, not yy_push_state (SC_COMMENT).
+
+	(letter, id): Don't assume ASCII; e.g., spell out a-z.
+
+	({int}, handle_action_dollar, handle_action_at): Check for integer
+	overflow.
+
+	(YY_STEP): Omit trailing semicolon, so that it's more like C.
+
+	(<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER>): Allow \0 and \00
+	as well as \000.  Check for UCHAR_MAX, not 255.
+	Allow \x with an arbitrary positive number of digits, as in C.
+	Check for overflow here.
+	Allow \? and UCNs, for compatibility with C.
+

+	* src/output.c (prepare_symbols): When printing token names,
+	escape "[" as "@<:@" and likewise for "]".
+
+	* src/system.h (errno): Remove declaration, as we are now
+	assuming C89 or better, and C89 guarantees errno.
+
+2002-10-30  Paul Eggert  <eggert@twinsun.com>
+
+	* lib/bitset_stats.c (bitset_stats_read, bitset_stats_write):
+	Check for close failures.
+	* src/files.h (xfclose): Return void, not int, since it always
+	returned zero.
+	* src/files.c (xfclose): Likewise.  Report I/O error if ferror
+	indicates one.

+	and ferror.  xfclose now checks ferror.
+
+	* data/glr.c (YYLEFTMOST_STATE): Remove.
+	(yyreportTree): Use a stack-based leftmost state.  This avoids
+	our continuing battles with bogus warnings about initializers.
+

+
+	* src/system.h: Don't use #ifdef/#ifndef on HAVE_ values, only

+
+	* tests/calc.at (_AT_DATA_CALC_Y): Remove unused strcat declaration.
+	* tests/cxx-type.at (_AT_TEST_GLR_CALC): Include stdlib.h, since
+	we use malloc.  Don't assume 'A' through 'Z' are contiguous.
+	Don't assume strdup exists; POSIX says its an XSI extension.
+	Check for buffer overflow on input.
+
+2002-10-24  Akim Demaille  <akim@epita.fr>
+
+	* src/output.c (output_skeleton): Don't disable M4sugar comments
+	too soon: it results in comments being expanded.
+	* data/yacc.c, data/glr.c, data/lalr1.cc: Do it right before the
+	first output.
+
+2002-10-24  Akim Demaille  <akim@epita.fr>
+
+	* data/yacc.c (m4_int_type): New.
+	* data/c.m4 (m4_int_type): Don't use yysigned_char, but `signed
+	char' as only yacc.c wants K&R portability.
+	* data/glr.c (yysigned_char): Remove.
+	* data/lalr1.cc: Rename the trailing b4_name as b4_parser_class_name.
+	Reported by Quoc Peyrot.
+
+2002-10-23  Paul Eggert  <eggert@twinsun.com>
+
+	* src/main.c (main): With --trace=time, report times even if a
+	non-fatal error occurs.  Formerly, the times were reported in some
+	such cases but not in others.
+	* src/reader.c (reader): Just return if a complaint has been issued,
+	instead of exiting, so that 'main' can report times.
+
+2002-10-22  Akim Demaille  <akim@epita.fr>
+
+	* src/system.h: Include sys/types.
+	Reported by Bert Deknuydt.
+
+2002-10-23  Paul Eggert  <eggert@twinsun.com>
+
+	* configure.ac (AC_PROG_LEX): Use instead of AM_PROG_LEX.
+	Suggested by Art Haas.

+2002-10-22  Paul Eggert  <eggert@twinsun.com>
+
+	* src/complain.c (exit) [! (STDC_HEADERS || _LIBC)]: Remove exit
+	decl; not needed any more.
+	* src/main.c (main): Use return to exit, undoing yesterday's change.
+	The last OS that we could find where this wouldn't work is
+	SunOS 3.5, and that's too old to worry about now.
+
+	* data/glr.c (struct yyltype): Define members even when not
+	doing locations.  This is more consistent with yacc.c, and it
+	works around the following bug reports:
+	http://mail.gnu.org/archive/html/bug-bison/2002-10/msg00106.html
+	http://mail.gnu.org/archive/html/bug-bison/2002-10/msg00111.html
+
+	* doc/bison.texinfo: Minor spelling and typographical fixes.  Use
+	@acronym consistently.  Standardize on "Yacc" instead of "YACC",
+	"Algol" instead of "ALGOL".  Give a bit more history about BNF.
+
+2002-10-22  Akim Demaille  <akim@epita.fr>
+
+	* data/README: New.
+
+2002-10-21  Paul Eggert  <eggert@twinsun.com>
+
+	Be consistent about 'bool'; the old code used an enum in one
+	module and an int in another, and this violates the C standard.
+	* m4/stdbool.m4: New file, from coreutils 4.5.3.
+	* configure.ac (AC_HEADER_STDBOOL): Add.
+	* m4/Makefile.am (EXTRA_DIST): Add stdbool.m4.
+	* src/muscle_tab.c (hash_compare_muscles): (a ? FALSE : TRUE) -> (! a)
+	* src/symtab.c (hash_compare_symbol_t): Likewise.

+	with ../lib/hash.c.  All uses changed.
+
+	* src/complain.c (warning_issued): Renamed from warn_message_count,
+	so that we needn't worry about integer overflow (!).
+	Now of type bool.  All uses changed.
+	(complaint_issued): Renamed from complain_message_count; likewise.
+
+	* src/main.c (main): Use exit to exit with failure.
+
+	* src/complain.c (fatal_at, fatal): Use EXIT_FAILURE and EXIT_SUCCESS
+	rather than 1 and 0.

+
+	* src/getarg.c (getargs): Remove duplicate code for
+	"Try `bison --help'".
+
+	* src/files.c (xfopen, xfclose): Use EXIT_FAILURE rather than 2.
+	What was that "2" for?
+
+	* src/complain.h (fatal, fatal_at): Add __attribute__((__noreturn__)).
+	* src/getargs.c (usage): Likewise.
+
+	* src/getargs.c (getargs): When there are too few operands, report
+	the last one.  When there are too many, report the first extra
+	one.  This is how diffutils does it.
+
+2002-10-20  Paul Eggert  <eggert@twinsun.com>
+
+	Remove K&R vestiges.
+	* configure.ac (AC_C_CONST, AM_C_PROTOTYPES): Remove.

+	fatal): Assume prototypes.
+	* src/complain.h: Assume prototypes.
+	* src/system.h (PARAMS): Remove.
+	Include <limits.h> unconditionally, since it's guaranteeed even
+	for a freestanding C89 compiler.
+	(SHRT_MIN, SHRT_MAX): Remove, since C89 guarantees them.
+	* src/vmsgetargs.c (getargs, cli_present, cli_get_value): Prototype.
+

+	* data/yacc.c (yyparse): Prototype and define thanks to these.
+	Adjust b4_c_function_def uses.
+	* data/glr.c (yyparse): Likewise, but ANSI only.

+	These.
+
+2002-10-19  Paul Eggert  <eggert@twinsun.com>
+
+	Do not create a temporary file, as that involves security and

+	Derived from a suggestion by Florian Krohm.
+	* lib/subpipe.c, lib/subpipe.h, m4/subpipe.m4: New files.

+	Read from stream rather than file.
+
+	* lib/timevar.c (TICKS_TO_MSEC, CLOCKS_TO_MSEC): Do not cast to
+	float, as this generates a warning on Solaris 8 + GCC 3.2 with
+	--enable-gcc-warnings.  Instead, divide into 1.0 rather than 1;
+	this generates a more-accurate value anyway.
+
+	* lib/timevar.c (timervar_accumulate): Rename locals to
+	avoid confusion with similarly-named more-global.
+	* src/muscle_tab.c (muscle_pair_list_grow): Likewise.

+	b4_c_function_call.
+
+2002-10-19  Akim Demaille  <akim@epita.fr>

+
+2002-10-19  Akim Demaille  <akim@epita.fr>
+
+	* src/getargs.c (usage): Take status as argument and exit
+	accordingly.
+	Report the traditional `Try ... --help' message when status != 0.
+	(usage, version): Don't take a FILE * as arg, it is pointless.
+	(getargs): When there is an incorrect number of arguments, make it
+	an error, and report it GNUlically thanks to `usage ()'.
+
+2002-10-18  Paul Eggert  <eggert@twinsun.com>
+
+	* data/glr.c (yyreportParseError): Don't assume that sprintf
+	yields the length of the printed string, as this is not true
+	on SunOS 4.1.4.  Reported by Peter Klein.
+
+	* tests/calc.at (_AT_DATA_CALC_Y): #undef memcmp and realloc.
+	* tests/conflicts.at (%nonassoc and eof): Likewise.

+2002-10-15  Paul Eggert  <eggert@twinsun.com>
+
+	Stop using the "enum_" trick for K&R-style function definitions;

+
+	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.

+	GLR parsers sometimes raise parse errors instead of performing the

+
+	* tests/calc.at (_AT_CHECK_CALC, _AT_CHECK_CALC_ERROR): Don't

+	(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.

+	"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.

+
+	* src/reader.c (grammar_current_rule_check):

+	visible here.
+	* data/yacc.c (yyreport_parse_error): Rename yylocation as yylloc
+	for the time being: %locations ought to provide it to yyerror.
+
+2002-07-25  Akim Demaille  <akim@epita.fr>
+
+	* src/output.c (prepare_tokens): Go up to ntokens, not ntokens + 1.
