+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_copy_, bitset_op4_cmp, bitset_and_or_cmp_, bitset_andn_or_cmp_,
+	bitset_or_and_cmp_): Likewise.

+	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.

+	graph_flag): Likewise.
+	* src/getargs.h (debug_flag, defines_flag, locations_flag,

+	* 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,

+	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
+	just before "|" as required by POSIX.
+	* tests/input.at (Torturing the Scanner): Add tests for ";|" in a
+	grammar.
+
+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>
+
+	* lib/bitset.h (BITSET_FOR_EACH, BITSET_FOR_EACH_REVERSE):
+	Do not overrun array bounds.
+	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):
+	Quote AC_FOREACH variable-expansions properly.
+	The 2003-01-03 obstack.h change also needs merging.
+	{end of changes requiring merging}
+
+	* lib/stdbool.h.in, m4/alloca.m4, m4/dirname.m4, m4/dos.m4,
+	m4/getopt.m4, m4/hash.m4, m4/malloc.m4, m4/memchr.m4,
+	m4/memrchr.m4, m4/obstack.m4, m4/onceonly.m4, m4/quote.m4,
+	m4/quotearg.m4, m4/realloc.m4, m4/stpcpy.m4, m4/strnlen.m4,
+	m4/strtol.m4, m4/strtoul.m4, m4/unlocked-io.m4, m4/xalloc.m4:
+	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,
+	m4/memcmp.m4, m4/prereq.m4, m4/stdbool.m4: Update to current
+	gnulib sources.
+
+	* configure.ac (gl_DIRNAME, gl_GETOPT, gl_HASH, gl_QUOTE, gl_XALLOC):
+	Add.
+	(gl_ERROR): New, replacing jm_PREREQ_ERROR.
+	(gl_FUNC_ALLOCA): New, replacing AC_FUNC_ALLOCA.
+	(gl_FUNC_STPCPY): New, replacing AC_REPLACE_FUNCS(stpcpy).
+	(gl_FUNC_STRNLEN): New, replacing AC_FUNC_STRNLEN.
+	(gl_MBSWIDTH): New, replacing jm_PREREQ_MBSWIDTH.
+	(gl_OBSTACK): New, replacing AC_FUNC_OBSTACK.
+	(gl_QUOTEARG): New, replacing jm_PREREQ_QUOTEARG.
+	(jm_FUNC_GLIBC_UNLOCKED_IO, gl_FUNC_STPCPY, gl_FUNC_STRTOL): New.
+	(jm_FUNC_MALLOC): New, replacing AC_FUNC_MALLOC.
+	(jm_FUNC_REALLOC): New, replacing AC_FUNC_REALLOC.
+	(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)
+	(AT_COMPILE, AT_COMPILE_CXX, AT_PARSER_CHECK): Move to...
+	* tests/local.at: here.
+	(AT_COMPILE_CXX): Tags the tests using it as c++.
+	Ignore the test if CXX is not functional.
+
+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
+	around a UnixWare 7.1.1 porting bug reported by John Hughes in
+	<http://mail.gnu.org/archive/html/bug-bison/2003-02/msg00030.html>.
+
+2003-02-26  Paul Eggert  <eggert@twinsun.com>
+
+	* README: Mention compiler bug in Sun Forte Developer 6 update 2.
+	Remove Sequent/Pyramid discussion (nobody uses them any more).
+	Merge VMS and MS-DOS discussion; these ports may well be dead
+	but let's keep mentioning them for now.  Put <> around email
+	addresses.  Add copyright notice.
+
+2003-02-24  Paul Eggert  <eggert@twinsun.com>
+
+	* data/glr.c (yy_reduce_print): yylineno -> yylno,
+	to avoid collision with flex use of yylineno.
+	Problem reported by Bruce Lilly in
+	<http://mail.gnu.org/archive/html/bug-bison/2003-02/msg00016.html>.
+	* data/lalr1.cc (yy::]b4_parser_class_name[::parse): Likewise.
+	* data/yacc.c (yy_reduce_print): Likewise.
+
+	* config/depcomp: Sync with Automake 1.7.3.
+
+2003-02-21  Akim Demaille  <akim@epita.fr>
+
+	* data/lalr1.cc: Use temporary variables instead of casts to
+	change integer types.
+	Suggested by Paul Eggert.
+
+2003-02-21  Akim Demaille  <akim@epita.fr>
+
+	* doc/bison.texinfo: Use "location" consistently to refer to @n,
+	to avoid confusions with lalr1.cc's notion of Position.
+	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>
+
+	* data/lalr1.cc (b4_stack_depth_init, yy::Parser::initdepth_):
+	Remove, useless.
+	(YYABORT, YYACCEPT, YYERROR): New.
+	* tests/calc.at: Renable the lalr1.cc test.
+
+2003-02-19  Akim Demaille  <akim@epita.fr>
+
+	* tests/calc.at (AT_CHECK_CALC): Check different scenarios of
+	error recovery, mixing with/without pops and discarding of the
+	lookahead.
+	Exercise YYERROR.
+	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.
+	* tests/testsuite.at (AT_COMPILE): Use them.
+	This fixes the testsuite problem reported by Robert Lentz in
+	<http://mail.gnu.org/archive/html/bug-bison/2003-02/msg00011.html>.
+
+2003-02-12  Paul Eggert  <eggert@twinsun.com>
+
+	* data/yacc.c (yyerrlab) [YYERROR_VERBOSE]:
+	Avoid subscript error in yycheck.  Bug reported by Andrew Suffield in
+	<http://mail.gnu.org/archive/html/bug-bison/2003-02/msg00003.html>.
+	* data/glr.c (yyreportSyntaxError) [YYERROR_VERBOSE]: Likewise.
+	Check for malloc failure, for consistency with yacc.c.
+	(yytname_size): Remove, for consistency with yacc.c.
+
+	The bug still remains in data/lalr1.cc, as I didn't have time
+	to fix it there.
+
+2003-02-06  Akim Demaille  <akim@epita.fr>
+
+	* configure.ac (GXX): Rename as...
+	(CXX): this, to keep the original Autoconf semantics.

+	* tests/calc.at (_AT_DATA_CALC_Y): Adjust yyerror to report the
+	locations in a more synthetic way.
+	(AT_CHECK_PUSHDEFS): AT_YYERROR_SEES_LOC_IF is positive if
+	lalr1.cc is used.
+	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.
+	(LOC, VAL, YYLLOC_FORMAL, YYLLOC_ARG, USE_YYLLOC, LEX_FORMALS)
+	(LEX_ARGS, USE_LEX_ARGS, LEX_PRE_FORMALS, LEX_PRE_ARGS): Replace

+
+2003-02-04  Akim Demaille  <akim@epita.fr>
+
+	* data/lalr1.cc (YYLLOC_DEFAULT): Fix its definition: be based on
+	Location as is defined.
+
+2003-02-04  Akim Demaille  <akim@epita.fr>
+
+	* data/lalr1.cc: If YYDEBUG is not defined, don't depend upon
+	name_ being defined.
+
+2003-02-03  Paul Eggert  <eggert@twinsun.com>
+
+	* src/gram.h (start_symbol): Remove unused decl.
+
+	Use more-consistent naming conventions for local vars.
+
+	* src/derives.c (derives_compute): Change type of local var from
+	int to rule_number.
+	* src/gram.c (grammar_rules_partial_print): Likewise.
+	* src/print.c (print_core): Likewise.

+	var.
+
+	* src/system.h (xstrndup, strchr, strspn, strnlen, memchr, memrchr):

+	get_view_str, get_linestyle_str, get_arrowstyle_str): Rename
+	param to have same name as that of enum, so that we don't use
+	"s" to stand for a non-state.
+
+2003-02-02  Akim Demaille  <akim@epita.fr>
+
+	* src/scan-skel.l: Scan more than one inert character per yylex
+	invocation.
+
+2003-02-01  Paul Eggert  <eggert@twinsun.com>
+
+	Version 1.875a.
+
+	* po/LINGUAS: Add ms.
+
+2003-01-30  Akim Demaille  <akim@epita.fr>
+
+	* doc/Makefile.am (CLEANFILES): Add bison.fns for distcheck.
+
+2003-01-29  Paul Hilfinger  <Hilfinger@CS.Berkeley.EDU>
+
+	* tests/cxx-type.at: Correct apparent typo in Bison input: $$ instead
+	of $1.
+
+	Changes in response to error report by S. Eken: GLR mode does not
+	handle negative $ indices or $ indices in embedded rules correctly.
+	See <http://mail.gnu.org/archive/html/bug-bison/2003-01/msg00076.html>.
+
+	* data/glr.c (b4_rhs_value): Change to use YYFILL macro.
+	(b4_rhs_location): Ditto.
+	(yyfill): New function to copy from stack tree into array
+	incrementally.
+	(yyuserAction): Modify to allow incremental move of semantic values
+	to rhs array when in GLR mode.
+	Define YYFILL to use in user-defined actions to fill semantic array
+	as needed.
+	Remove dummy use of yystack, as there is now a guaranteed use.
+	(yydoAction): Modify to allow incremental move of semantic values
+	to rhs array when in GLR mode.
+	(yyresolveAction): Ditto.
+	(yyglrShiftDefer): Update comment.
+	(yyresolveStates): Use X == NULL for pointers, not !X.
+	(yyglrReduce): Ditto.
+	(yydoAction): Ditto
+
+	* tests/glr-regr1.at: Rename to ...
+	* tests/glr-regression.at: Add new regression test for the problems
+	described above (adapted from S. Eken).
+	Update copyright notice.
+	* tests/testsuite.at: Rename glr-regr1.at to glr-regression.at.
+	* tests/Makefile.am: Ditto.
+
+2003-01-28  Paul Eggert  <eggert@twinsun.com>
+
+	* data/lalr1.cc: Do not use @output_header_name@ unless
+	b4_defines_flag is set.  This fixes two bugs reported by
+	Tim Van Holder in
+	<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

+	(<INITIAL>"{"): Set token type.
+	(<SC_BRACED_CODE>"}"): Use it.
+	(handle_action_dollar, handle_action_at): Now returns bool

+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.

+
+	* configure.ac (AC_CHECK_TYPES): Check for uintptr_t.
+
+	* src/derives.c (derives_compute): Do not subtract NTOKENS from

+
+	* src/output.c (GENERATE_MUSCLE_INSERT_TABLE): Use long local

+	have to worry about alloca.
+	* src/state.c (state_hash_lookup): Likewise.
+
+	* src/scan-gram.l (<SC_ESCAPED_CHARACTER>"'"): Use unsigned char

+

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

+
+	* src/tables.c (table_size): Now int, to pacify GCC.
+	(table_grow, table_ninf_remap): Use signed table size.
+	(save_row): Don't bother initializing locals when not needed.

+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
+	needed to remove ambiguity.  All uses changed.

+	* tests/input.at (Torturing the Scanner): Rename value_t -> value,
+	value_t_as_yystype -> value_as_yystype.
+
+	Don't include <errno.h> in the mainstream code, since it

+
+	* data/glr.c, data/lalr1.cc, data/yacc.c: Do not use __file__,
+	since this causes problems when __file__ contains character

+	Instead, just use the file's basename.  This fixes the bug
+	reported by Martin Mokrejs in

+
+2002-12-06  Paul Eggert  <eggert@twinsun.com>
+
+	Add support for rules that do not have trailing semicolons, as
+	POSIX requires.  Improve the quality of locations in Bison
+	diagnostics.
+
+	* src/location.c: Include <quotearg.h>.
+	(empty_location): Now const.

+	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.
+	All member uses changed: file -> start.file or end.file (as needed),
+	first_line -> start.line, first_column -> start.column,
+	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.
+	(scanner_cursor): New var.
+	(adjust_location): Renamed from extend_location.  It now sets

+	Don't bother testing for CR.
+	(handle_syncline): Remove location arg; now updates scanner cursor.
+	All callers changed.
+	(unexpected_end_of_file): Now accepts start boundary of token or

+	(context_state): Renamed from c_context.  All uses changed.
+	(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.
+	(<SC_AFTER_IDENTIFIER>): New state, looking for a colon.

+	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>
+

+	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.

+
+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.

+
+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.

+
+	Pacify Sun ONE Studio 7 lint.  Also, rename "ParseError"
+	to "SyntaxError" for consistency with my 2002-11-15 change.
+
+	* data/glr.c (YYDPRINTF, YYDSYMPRINT, YYDSYMPRINTF) [!YYDEBUG]: Do
+	not define to {}, since this breaks the common use of `YYDPRINTF
+	((...));' if a single statement is desired (e.g. before `else').
+	Work around GCC warnings by surrounding corresponding calls with
+	{} if needed.
+	(yyhasResolvedValue): Remove unused function.
