+2004-12-25  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* NEWS: Version 2.0.  Reformat the existing news items since
+	1.875, so that related items are grouped together.
+	* configure.ac (AC_INIT): Bump version to 1.875f.
+	* src/parse-gram.c, src/parse-gram.h: Regenerate with 2.0.
+
+	* data/lalr1.cc (yydestruct_): Pacify unused variable warning
+	for yymsg, too.
+
+	* src/LR0.c (new_itemsets): Use memset rather than zeroing by
+	hand.  This avoids a warning about comparing int to size_t when
+	GCC warnings are enabled.
+
+2004-12-22  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* NEWS: Bison-generated parsers no longer default to using the
+	alloca function (when available) to extend the parser stack, due
+	to widespread problems in unchecked stack-overflow detection.
+	* data/glr.c (YYMAXDEPTH): Remove undef when zero.  It's the user's
+	responsibility to set it to a positive value.  This lets the user
+	specify a value that is not a preprocessor constant.
+	* data/yacc.c (YYMAXDEPTH): Likewise.
+	(YYSTACK_ALLOC): Define only if YYSTACK_USE_ALLOCA is nonzero.
+	* doc/bison.texinfo (Stack Overflow): YYMAXDEPTH no longer needs
+	to be a compile-time constant.  However, explain the constraints on it.
+	Also, explain the constraints on YYINITDEPTH.
+	(Table of Symbols): Explain that alloca is no longer the default.
+	Explain the user's responsibility if they define YYSTACK_USE_ALLOCA
+	to 1.
+
+	* doc/bison.texinfo (Location Default Action): Mention that n must
+	be zero when k is zero.  Suggested by Frank Heckenbach.
+
+2004-12-22  Akim Demaille  <akim@epita.fr>
+
+	* data/lalr1.cc (parser::token_number_type, parser::rhs_number_type)
+	(parser::state_type, parser::semantic_type, parser::location_type):
+	Private, not public.
+	(parser::parse): Return ints, not bool.
+	Returning a bool introduces a problem: 0 corresponds to false, and
+	it seems weird to return false on success.  Returning true changes
+	the conventions for yyparse.
+	Alternatively we could return void and send an exception.
+	There is no clear consensus (yet?).
+	(state_stack, semantic_stack, location_stack): Rename as...
+	(state_stack_type, semantic_stack_type, location_stack_type): these.
+	Private, not public.
+	* tests/c++.at: New.
+	* tests/testsuite.at, tests/Makefile.am: Adjust.
+
+2004-12-21  Akim Demaille  <akim@epita.fr>
+
+	* data/lalr1.cc (parser::parse): Return a bool instead of an int.
+
+2004-12-21  Akim Demaille  <akim@epita.fr>
+
+	Don't impose std::string for filenames.
+
+	* data/lalr1.cc (b4_filename_type): New.
+	(position::filename): Use it.
+	(parser.hh): Move the inclusion of stack.hh and location.hh below
+	the user code, so that needed headers for the filename type can be
+	included first.
+	Forward declare them before the user code.
+	* tests/Makefile.am (check-local, installcheck-local): Pass
+	TESTSUITEFLAGS to the TESTSUITE.
+
+2004-12-20  Akim Demaille  <akim@epita.fr>
+
+	Use more STL like names: my_class instead of MyClass.
+
+	* data/lalr1.cc (LocationStack, LocationType, RhsNumberType)
+	(SemanticStack, SemanticType, StateStack, StateType)
+	(TokenNumberType, Stack, Slice, Traits, Parser::location)
+	(Parser::value): Rename as...
+	(location_stack, location_type, rhs_number_type, semantic_stack)
+	(semantic_type, state_stack, state_type, token_number_type, stack)
+	(slice, traits, parser::yylloc, parser::yylval): these.
+
+	* tests/calc.at, tests/regression.at, tests/actions.at: Adjust.
+
+2004-12-19  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* data/glr.c (YYLLOC_DEFAULT): Use GNU spacing conventions.
+	* data/yacc.c (YYLLOC_DEFAULT): Likewise.
+
+2004-12-17  Paul Eggert  <eggert@cs.ucla.edu>
+
+	Remove uses of 'short int' and 'unsigned short int'.  This raises
+	some arbitrary limits.  It uses more memory but nowadays that's
+	not much of an issue.
+
+	This change does not affect the generated parsers; that's a different
+	task, as some users will want to conserve memory there.
+
+	Ideally we should use size_t to represent all object counts, and
+	something like ptrdiff_t to represent signed differences of object
+	counts; but that will require more code-cleanup than I have the
+	time to do right now.
+
+	* src/LR0.c (allocate_itemsets, new_itemsets, save_reductions):
+	Use size_t, not int or short int, to count objects.
+	* src/closure.c (nritemset, closure): Likewise.
+	* src/closure.h (nritemset, closure): Likewise.

+2004-12-17  Akim Demaille  <akim@epita.fr>
+
+	* data/lalr1.cc: Extensive Doxygenation.
+	(error_): Rename as...
+	(error): this, since it is visible to the user.
+	Adjust callers.
+	(Parser::message): Now an automatic variable from...
+	(Parser::yyreport_syntax_error_): here.
+	* tests/actions.at, tests/calc.at, tests/regression.at: Adjust to
+	Parser::error.
+	* tests/input.at: Escape $.
+
+2004-12-16  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* data/glr.c (b4_lhs_value, b4_rhs_value, b4_rhs-location):
+	Parenthesize rhs to avoid obscure problems with mistakes like
+	"foo$$bar = foo$1bar;".  Problem reported by twlevo at xs4all.
+	* data/lalr1.cc (b4_lhs_value, b4_rhs_value, b4_lhs_location,

+	* tests/actions.at: Re-enable C++ tests.
+
+2004-12-16  Akim Demaille  <akim@epita.fr>
+

+	real.
+
+2004-12-16  Akim Demaille  <akim@epita.fr>
+
+	Use #define to handle the %name-prefix.
+
+	* data/glr.c, data/yacc.c: Comment changes.
+	* data/lalr1.cc (yylex): Use #define to select the name of yylex,
+	so that one can refer to yylex in the parser file, and have it
+	renamed, as is the case with other skeletons.
+
+2004-12-16  Akim Demaille  <akim@epita.fr>
+
+	Move lalr1.cc internals into yy*.

+	(yydefact_, yypgoto_, yydefgoto_, yytable_, yytable_ninf_)
+	(yycheck_, yystos_, yyr1_, yyr2_, yyname_, yyrhs_, yyprhs_)
+	(yyrline_, yytoken_number_, yyeof_, yylast_, yynnts_, yyempty_)

+	(yynerrs_, yylooka_, yyilooka_, yyerror_range_, yynerrs_):
+	these.
+
+2004-12-15  Paul Eggert  <eggert@cs.ucla.edu>
+
+	Fix some problems reported by twlevo at xs4all.
+	* src/symtab.c (symbol_new): Report an error if the input grammar
+	contains too many symbols.  This is better than calling abort() later.
+	* src/vcg.h (enum layoutalgorithm): Remove.  All uses removed.
+	(struct node, struct graph):
+	Rename member expand to stretch.  All uses changed.
+	(struct graph): Remove member layoutalgorithm.  All uses removed.

+
+2004-12-15  Akim Demaille  <akim@epita.fr>

+	(yypop_, yyreport_syntax_error_, yytranslate_): this.
+
+2004-12-15  Akim Demaille  <akim@epita.fr>
+
+	* data/lalr1.cc (lex_): Rename as...
+	(yylex_): this.
+	Move the trace here.
+	Take the %name-prefix into account.
+	Reported by Alexandre Duret-Lutz.
+
+2004-12-15  Akim Demaille  <akim@epita.fr>
+
+	Simplify the C++ parser constructor.
+
+	* data/lalr1.cc (debug_): Rename as...
+	(yydebug_): so that the parser's internals are always in the yy*
+	pseudo namespace.
+	Adjust uses.
+	(b4_parse_param_decl): Remove the leading comma as it is now only
+	called as unique argument list.
+	(Parser::Parser): Remove the constructor accepting a location and

+	definitions and uses.
+
+2004-12-14  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* data/glr.c (struct yyGLRStack): yyerror_range now has 3 items,
+	not 2, since it's not portable to subtract 1 from the start of an
+	array.  The new item 0 is never set or used.  All uses changed.
+
+	(yyrecoverSyntaxError): Use YYLLOC_DEFAULT instead of assuming
+	the default definition of YYLLOC_DEFAULT.  Problem reported
+	by Frank Heckenbach.
+
+2004-12-12  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* data/glr.c (YYRHSLOC): Don't have two definitions, one for
+	the normal case and one for the error case.  Just use the
+	first one uniformly.  Problem reported by Frank Heckenbach.
+	(YYLLOC_DEFAULT): Use the conventions of yacc.c, so we can
+	use exactly the same macro in both places.
+	(yyerror_range): Now of type yyGLRStackItem, not YYLTYPE,
+	so that the normal-case YYRHSLOC works for the error case too.
+	All uses changed.
+	* data/yacc.c (YYRHSLOC): New macro, taken from glr.c.
+	(YYLLOC_DEFAULT): Use the same macro as glr.c.
+	* doc/bison.texinfo (Location Default Action): Don't claim that
+	we have an array of locations.  Use the same macro for both glr
+	and lalr parsers.  Mention YYRHSLOC.  Mention what happens when
+	the index is 0.
+
+2004-12-10  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* HACKING: Update email addresses to send announcements to.

+	* src/parse-gram.c, src/parse-gram.h: Regenerate with 1.875e.
+
+	* src/scan-skel.l: Include "complain.h", for "fatal".
+
+	* src/relation.h (relation_print, relation_digraph):
+	Relation sizes are of type relation_node, not size_t (this is
+	merely a doc fix, since the two types are equivalent).
+	(relation_transpose): Relation sizes are of type relation_node,
+	not int.
+	* src/relation.c: Likewise.
+	(top, infinity): Now of type relation_node, not int.
+	(traverse, relation_transpose): Use relation_node, not int.
+
+	* data/glr.c (yyuserAction, yyrecoverSyntaxError): Mark args
+	with ATTRIBUTE_UNUSED if they're not used, to avoid GCC warning.
+	(yyparse): Remove unused local introduced in 2004-10-25 patch.
+
+	* tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): New arg
+	specifying whether the test should be skipped.  Use it tp
+	specify that the [%defines %skeleton "lalr1.cc"] tests currently
+	fail on some hosts, and should be skipped.
+
+2004-12-08  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* src/system.h (CALLOC, MALLOC, REALLOC): Remove.  All callers
+	changed to use xcalloc, xnmalloc, xnrealloc, respectively,
+	unless otherwise specified below.
+
+	* src/LR0.c (allocate_itemsets): Use xnmalloc, not xcalloc,
+	to allocate kernel_base, kernel_items, kernel_size, since
+	they needn't be initialized to 0.
+	(allocate_storgae): Likewise, for shiftset, redset, shift_symbol.
+	* src/closure.c (new_closure): Likewise, for itemset.
+	* src/derives.c (derives_compute): Likewise, for delts, derives, q.
+	* src/lalr.c (set_goto_map): Likewise, for temp_map.

+	(goto_actions): Likewise for state_count.
+	(pack_table): Likewise for base, pos, check.
+	(tables_generate): Likewise for width.
+
+	* src/LR0.c (set_states): Don't reuse kernel_size and kernel_base
+	for initial core.  Just have a separate core, so we needn't worry
+	about whether kernel_size and kernel_base are initialized.
+
+	* src/LR0.c (shift_symbol, redset, shiftset, kernel_base,
+	kernel_size, kernel_items): Remove unnecessary initialization.

+	conflrow, conflict_table, conflict_list, table, check):
+	Likewise.
+
+	* src/closure.c (new_closure): Arg is of type unsigned int, not int.
+	This is because all callers pass unsigned int.
+	* src/closure.h (new_closure): Likewise.
+
+	* src/lalr.c (initialize_F): Initialize reads[i] in all cases.
+	(build_relations): Initialize includes[i] in all cases.
+	* src/reader.c (packgram): Always initialize rules[ruleno].prec
+	and rules[ruleno].precsym.  Initialize members in order.

+	and end_R[i].
+	* src/table.c (conflict_row): Initialize 0 at end of conflict_list.
+
+	* src/output.c (prepare_actions): Pass 0 instead of conflict_list[0];
+	conflict_list[0] was always 0, but now it isn't initialized.
+
+	* src/table.c (table_grow): When conflict_table grew, the grown
+	area wasn't cleared.  Fix this.
+
+	* lib/.cvsignore: Add strdup.c, strdup.h.
+	* m4/.cvsignore: Add strdup.m4.
+
+2004-12-07  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* src/lalr.h (GOTO_NUMBER_MAXIMUM): New macro.
+	* src/lalr.c (set_goto_map): Don't allow ngotos to equal
+	GOTO_NUMBER_MAXIMUM, since we occasionally compute
+	ngotos + 1 without checking for overflow.
+	(build_relations): Use END_NODE, not -1, to denote end of edges.
+	* src/lalr.c (set_goto_map, map_goto, initialize_F, add_loopback_edge,
+	build_relations): Use goto_number, not int, for goto numbers.
+	* src/tables.c (save_column, default_goto): Likewise.
+
+2004-11-23  Akim Demaille  <akim@epita.fr>
+
+	* data/lalr1.cc (YYSTYPE): Define it as is done for C, instead
+	of #defining from yystype.
+	Don't typedef yystype, C++ does not need it.
+	This lets it possible to forward declare it as union.
+
+2004-11-23  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* bootstrap (gnulib_modules): Add extensions.
+	Problem reported by Jim Meyering.
+
+2004-11-22  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* src/LR0.c, src/closure.c, src/derives.c, src/gram.c,
+	src/lalr.c, src/nullable.c, src/relation.c, src/scan-skel.l,
+	src/system.h, src/tables.c: XFREE -> free, to accommodate
+	recent change to gnulib xalloc.h.
+	Problem reported by Jim Meyering.
+
+2004-11-17  Akim Demaille  <akim@epita.fr>

+	(Parser::debug_stream, Parser::set_debug_stream): New.
+	(Parser::symprint_): Define cdebug_ for temporary backward
+	compatibility.
+	* tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Use

+
+	* data/lalr1.cc (Parser:print_): Remove, use %printer instead.
+	* tests/regression.at (_AT_DATA_DANCER_Y): Adjust.

+
+2004-10-27  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* data/glr.c (yyloc_default): Remove; not used.
+	Problem reported by Frank Heckenbach.
+
+2004-10-25  Akim Demaille  <akim@epita.fr>
+
+	* data/glr.c (YYRHSLOC): Move its definition next to its uses.
+	Introduce another definition to address simple location arrays.
+	(yyGLRStack): New member: yyerror_range.
+	(yyrecoverSyntaxError, yyparse): Update it.
+	(yyrecoverSyntaxError): Use it when shifting the error token to
+	have an accurate range, equivalent to the one computed by both
+	yacc.c and lalr1.cc.
+	* tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Change its yylex so
+	that column numbers start at column 0, as per GNU Coding
+	Standards, the others tests, and the doc.
+	(_AT_RESOLVED_GLR_OUTPUT_WITH_LOC, _AT_AMBIG_GLR_OUTPUT_WITH_LOC):
+	Adjust to the above change (first column is 0).
+	And adjust the location of the "<error>", now covering the whole
+	line.
+
+2004-10-22  Akim Demaille  <akim@epita.fr>
+       and  Paul Eggert  <eggert@cs.ucla.edu>
+
+	Remove some arbitrary limits on goto numbers and relations.
+	* src/lalr.c (goto_map, ngotos, from_state, to_state): Omit
+	initial values, since they're never used.
+	(set_goto_map): ngotos is now unsigned, so test for overflow
+	by seeing whether it wraps around to zero.
+	* src/lalr.h (goto_number): Now size_t, not short int.
+	(GOTO_NUMBER_MAXIMUM): Remove.
+	* src/relation.c (relation_print, traverse, relation_transpose):
+	Check for END_NODE rather than looking at sign.
+	* src/relation.h (END_NODE): New macro.
+	(relation_node): Now size_t, not short int.
+
+2004-10-22  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* doc/bison.texinfo (Language and Grammar): In example, "int" is a
+	keyword, not an identifier.  Problem reported by Baron Schwartz in
+	<http://lists.gnu.org/archive/html/bug-bison/2004-10/msg00017.html>.
+
+2004-10-11  Akim Demaille  <akim@epita.fr>

+	value.
+	(redeclaration): New.
+	Use it to factor redeclaration complaints.
+	(symbol_make_alias): Don't set the type of the alias, let
+	symbol_check_alias_consistency do it as for other features.

+
+2004-10-09  Paul Eggert  <eggert@cs.ucla.edu>

+
+	In Bison 1.875's yacc.c, YYLLOC_DEFAULT was called regardless
+	whether the reducion was empty or not.  This leaves room to
+	improve the use of YYLLOC_DEFAULT in such a case.
+	lalr1.cc is still experimental, so changing this is acceptable.
+	And finally, there are probably not many users who changed the
+	handling of locations in GLR, so changing is admissible too.
+
+	* data/glr.c, data/lalr1.cc, data/yacc.c (YYLLOC_DEFAULT): On an
+	empty reduction, set @$ to an empty location ending the previously
+	stacked symbol.
+	Adjust uses to make sure the code is triggered on empty
+	reductions.
+	* tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust the
+	expected output: empty reductions have empty locations.
+
+2004-09-29  Akim Demaille  <akim@epita.fr>
+
+	* data/lalr1.cc: Move towards a more standard C++ coding style
+	for templates: Class < T > -> Class<T>.
+
+2004-09-29  Akim Demaille  <akim@epita.fr>
+
+	* data/lalr1.cc: Reinstall the former ctor, for sake of
+	compatibility, but warn it will be removed.
+	Move towards a more standard C++ coding style (i.e., type *var ->
+	type* var).
+
+2004-09-27  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* src/parse-gram.y (add_param): Rewrite to avoid strchr,
+	since it's less likely to work if NULs are involved in the future.
+
+2004-09-27  Akim Demaille  <akim@epita.fr>
+
+	* data/yacc.c (YY_LOCATION_PRINT): Fix its default declaration.
+
+2004-09-27  Akim Demaille  <akim@epita.fr>
+
+	* data/lalr1.cc (b4_parse_param_decl_1): New.

+
+2004-09-24  Akim Demaille  <akim@epita.fr>
+

+	the useless parentheses.
+	Suggested by Paul Eggert.
+
+2004-09-20  Akim Demaille  <akim@epita.fr>
+
+	Let the initial-action act on the look-ahead, and use it for the
+	"initial push" (corresponding to an hypothetical beginning-of-file).
+	And let lalr1.cc honor %initial-action.
+
+	* doc/bison.texinfo (Initial Action Decl): Clarify, and add an
+	example.
+	* data/lalr1.cc (Parser::initlocation_): Remove, bad experiment.
+	(Parser::Parser): Remove the ctor that used to initialize it.
+	(Parser::parse): Like in the other skeletons, issue the "starting
+	parse" message before any action.
+	Honor %initial-action.
+	Initialize the stacks with the lookahead.
+	* data/yacc.c: Let $$ and @$ in %initial-action designate the
+	look-ahead.
+	Push them in the stacks.
+	* tests/actions.at, tests/calc.at: Adjust the C++ ctor invocations.
+
+2004-09-20  Akim Demaille  <akim@epita.fr>
+
+	* doc/bison.texinfo (Initial Action Decl): New.
+
+2004-09-20  Akim Demaille  <akim@epita.fr>
+
+	* data/yacc.c (YY_LOCATION_PRINT): Use YYLTYPE_IS_TRIVIAL as a
+	clearer criterion to define it.
+	(parse): Initialize the initial location when YYLTYPE_IS_TRIVIAL.
+	When reducing on an empty RHS, use the latest stacked location as
+	location.
+	yylloc is not always available.
+	* data/glr.c: Likewise.
+	Also, honor initial-actions.
+
+2004-09-20  Akim Demaille  <akim@epita.fr>
+
+	* data/yacc.c (YY_LOCATION_PRINT): New.
+	Define when we know YYLTYPE's structure, i.e., when the default
+	YYLLOC_DEFAULT is used.
+	* data/c.m4 (b4_yysymprint_generate): Use it.
+	* data/lalr1.cc (YYLLOC_DEFAULT): Stop relying on the initial
+	value of the result.
+	(error_start_): Replace with...
+	(error_range_): this location array.
+	This allows to replace code relying on the implementation of
+	locations by portable code.
+	* data/yacc.c (yylerrsp): Replace with...
+	(yyerror_range): this.
+	Every time a token is popped, update yyerror_range[0], to have an
+	accurate location for the error token.
+	* data/glr.c (YY_LOCATION_PRINT): New.
+	(yyprocessOneStack): Fix an invocation of YY_SYMBOL_PRINT:
+	deference a pointer.
+	* tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): No longer
+	report the location in %printers.
+
+	* src/scan-skel.l: Instead of abort, report error messages to ease
+	understanding skeleton scanning failures.
+
+2004-09-16  Akim Demaille  <akim@epita.fr>
+
+	* data/lalr1.cc (Stack::Iterator, Stack::ConstIterator): Rename as...
+	(iterator, const_iterator): these, to be more in the C++ spirit.
+	Also, return reverse iterators so that when displaying the stack
+	we display its bottom first.
+	(Parser::stack_print_, Parser::reduce_print_): Match the messages
+	from yacc.c.
+	We should probably use vector here though.
+
+2004-09-16  Akim Demaille  <akim@epita.fr>
+
+	Have more complete shift traces.
+
+	* data/yacc.c, data/lalr1.c, data/glr.c: Use YY_SYMBOL_PRINT
+	to report Shifts instead of ad hoc YYDPRINTF invocations,
+	including for the error token.
+	* data/lalr1.cc (symprint_): Output the location.
+	* tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): In C++, don't
+	output the location within the %printer.
+	Activate GLR tests, at least to make sure they compile properly.
+	They still don't pass though.
+	* tests/calc.at: Adjust expect verbose output, since now "Entering
+	state..." is on a different line than the "Shifting" message.
+
+2004-09-08  Akim Demaille  <akim@epita.fr>
+
+	* tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Move the
+	Bison directive from the Bison file to the invocation of this
+	macro, so that these directives are passed to
+	AT_BISON_OPTION_PUSHDEFS to get correct help macros.
+	Use these helping macros (e.g., AT_LOC, AT_VAL and so forth).
+	Move the AT_SETUP/AT_CLEANUP outside, to report as test title
+	the extra Bison directives instead of the whole series.
+	Change the grammar so that there are recoverable errors, and
+	unrecoverable errors.  Now we can have the parser give up before
+	consuming the whole input.  As a result we now can observe that
+	the lookahead is freed when needed.
+	Change the parser source to parse argv[1] instead of a hard coded
+	string.
+	Simplify yylex, and give a value and location to EOF.
+	Simplify some invocations of AT_CHECK_PRINTER_AND_DESTRUCTOR that
+	passed directives already coded in the file.
+	Add some tests to check the location of "error".
+	For some tests, the C++ parser is correct, and not yacc.c.
+	For other tests, they provide different, but unsatisfying, values,
+	so keep the C++ value so that at least one parser is "correct"
+	according to the test suite.
+	(Actions after errors): Remove, this is subsumed by the
+	AT_CHECK_PRINTER_AND_DESTRUCTOR series.
+
+2004-09-06  Akim Demaille  <akim@epita.fr>
+
+	* data/lalr1.cc: Adjust the indentation of the labels.
+        (Parser::pop): New.
+	Use it.
+
+2004-09-06  Akim Demaille  <akim@epita.fr>
+
+	* data/yacc.cc, data/glr.cc (yydestruct): Accept an additional
+	argument, an informative message.
+	Call YY_SYMBOL_PRINT.
+	Adjust all callers: integrate the associated YY_SYMBOL_PRINT.
+	* data/lalr1.cc (destruct_): Likewise.
+	In addition, no longer depend on b4_yysymprint_generate and
+	b4_yydestruct_generate to generate these functions, do it "by
+	hand".
+
+2004-09-03  Akim Demaille  <akim@epita.fr>
+
+	* data/glr.c, data/lalr1.cc, data/yacc.c: When YYABORT was
+	invoked, yydestruct the lookahead.
+	* tests/calc.at (Calculator $1): Update the expected lengths of
+	traces: there is an added line for the discarded lookahead.
+	* doc/bison.texinfo (Destructor Decl): Some rewording.
+	Define "discarded" symbols.
+
+2004-09-02  Akim Demaille  <akim@epita.fr>
+

+
+	* data/glr.c, yacc.c (YYDSYMPRINT): Remove, not used.
+	(YYDSYMPRINTF): Rename as...
+	(YY_SYMBOL_PRINT): this.
+	* data/lalr1.cc (YY_SYMBOL_PRINT): New, modeled after the previous
+	two.
+	Use it instead of direct symprint_ calls.
+	(yybackup): Tweak the "Now at end of input" case to match yacc.c's
+	one.
+
+2004-09-02  Akim Demaille  <akim@epita.fr>
+
+	* data/lalr1.cc (b4_yysymprint_generate): New.
+	(symprint_): New member function, defined when YYDEBUG.
+	Use it consistently instead of token/nterm debugging output by
+	hand.
+	* tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust
+	%printer calls to use cdebug_ when using lalr1.cc.
+
+2004-08-30  Florian Krohm  <florian@edamail.fishkill.ibm.com>
+
+	* data/glr.c: Guard the declarations of yypstack and yypdumpstack
+	with #ifdef YYDEBUG.
+
+2004-08-26  Akim Demaille  <akim@epita.fr>
+
+	* doc/bison.texinfo (Implementing Loops): Rename as...
+	(Implementing Gotos/Loops): this.
+
+2004-08-13  Paul Eggert  <eggert@cs.ucla.edu>
+
+	Adjust to latest gnulib.
+	* bootstrap (gnulib_modules): Add xalloc-die.
+	Set LC_ALL=C so that file names sort consistently.
+	Prefer the gnulib copies of gettext.m4, glibc21.m4,
+	inttypes_h.m4, lib-ld.m4, lib-prefix.m4, po.m4, stdint_h.m4,
+	uintmax_t.m4, ulonglong.m4.
+	(intl_files_to_remove): Add gettext.m4, lib-ld.m4, lib-prefix.m4,
+	po.m4 since we are now using _gl.m4 instead.
+
+2004-08-10  Florian Krohm  <florian@edamail.fishkill.ibm.com>
+
+	* src/scan-action.l: Remove. Scanning of semantic actions is
+	handled in scan-gram.l.
+
+2004-08-07  Florian Krohm  <florian@edamail.fishkill.ibm.com>
+
+	* src/scan-gram.l (handle_syncline): Use uniqstr_new not xstrdup.
+
+	* src/location.h (struct): The file member is a uniqstr.
+	(equal_boundaries): Use UNIQSTR_EQ for comparison.
+
+2004-07-22  Paul Eggert  <eggert@cs.ucla.edu>
+
+	Fix bug with non-%union parsers that have printers or destructors,
+	which led to a Bison core dump.  Reported by Peter Fales in
+	<http://lists.gnu.org/archive/html/bug-bison/2004-07/msg00014.html>.
+
+	* data/c.m4 (b4_symbol_actions): Don't assume %union was used.
+	* data/lalr1.cc (yystype) [defined YYSTYPE]: Define to YYSTYPE,
+	not to our own type.
+	* src/output.c (symbol_destructors_output, symbol_printers_output):
+	Don't assume %union.
+	* tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR,
+	AT_CHECK_PRINTER_AND_DESTRUCTOR): New argument
+	UNION-FLAG.  All callers changed.
+	(_AT_CHECK_PRINTER_AND_DESTRUCTOR): Don't assume %union.
+	Use type char, not unsigned int, when declaring an array of char;
+	this lets us remove a cast.
+	(Printers and Destructors): Add non-%union test cases.
+
+2004-06-21  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* doc/bison.texinfo: Minor editorial changes, mostly to the new
+	GLR writeups.  E.g., avoid frenchspacing and the future tense,

+	respect to".
+
+2004-06-21  Paul Hilfinger  <hilfingr@CS.Berkeley.EDU>
+
+	* doc/bison.texinfo (Merging GLR Parses, Compiler Requirements):

+2004-05-29  Paul Eggert  <eggert@cs.ucla.edu>
+
+	Fix some "make check" problems with C++ reported by

+	C++ compiler.  (trivial change)
+
+2004-05-27  Paul Eggert  <eggert@cs.ucla.edu>
+
+	Spent a few hours checking out which prerequisite versions the
+	current sources actually require.  I went all the way back to
+	Gettext 0.10.40, Automake 1.4, and Autoconf 2.57 and investigated
+	a seemingly endless set of combinations of versions more recent
+	than that.  The bottom line is that the current sources require
+	fairly recent versions of the build tools, and it'll be some work
+	to change this.
+	* configure.ac (AC_PREREQ): Increase from 2.58 to 2.59.
+	(AM_INIT_AUTOMAKE): Increase from 1.7 to 1.8.
+	(AM_GNU_GETTEXT_VERSION): Increase from 0.11.5 to 0.12.
+	Add comments explaining why those particular versions are
+	currently needed.
+
+	* src/parse-gram.y (lloc_default): Rewrite to avoid compiler bug
+	in SGI MIPSpro 7.4.1m.  Problem reported by Albert Chin-A-Young in
+	<http://lists.gnu.org/archive/html/bug-bison/2004-05/msg00037.html>.
+
+	* configure.ac (AC_PREREQ): Bump to 2.58, since 2.57 doesn't work
+	(it fails with a Autoconf-without-aclocal-m4 diagnostic).
+
+2004-05-26  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* configure.ac (AM_GNU_GETTEXT_VERSION): Lower it from 0.14.1 to
+	0.11.5.  Suggested by Bruno Haible.
+	* bootstrap: Remove gettext version checking.
+
+	* doc/bison.texinfo (Decl Summary): Also mention that %union
+	can depend on prerequisite types.  Problem reported by Tim
+	Van Holder.
+
+2004-05-25  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* README: Mention GNU m4 1.4 bugs and Akim's patched version.
+	* README-alpha: Don't tell people not to package this.

+
+	* doc/bison.texinfo (Decl Summary, Bison Options): Clarify what's

+	defined as a macro.
+
+2004-05-24  Paul Eggert  <eggert@cs.ucla.edu>
+
+	Undo change made earlier today: it caused autopoint to not bring
+	in ABOUT-NLS.  Ouch.  Instead, substitute our own diagnostic for
+	autopoint's.
+
+	* bootstrap: Check that gettext version matches what's in
+	configure.ac.  Warn users to ignore robots.txt ERROR 404.
+	* bootstrap: Undo today's earlier change (logged below).
+	* configure.ac (AM_GNU_GETTEXT_VERSION): Likewise.
+
+	The gettext version checking is causing more trouble than it's
+	curing; remove it.  Problem reported by Paul Hilfinger.
+
+	* bootstrap: Issue a warning that one can expect a message
+	'AM_GNU_GETTEXT is used, but not AM_GNU_GETTEXT_VERSION'.
+	* configure.ac (AM_GNU_GETTEXT_VERSION): Remove.
+
+2004-05-23  Paul Eggert  <eggert@cs.ucla.edu>
+
+	Ensure that the C++ compiler used for testing actually works on a

+
+	* configure.ac (AC_INIT): Update to 1.875e.
+
+2004-05-21  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* NEWS: Version 1.875d.
+	* configure.ac (AC_INIT): Likewise.
+	* src/parse-gram.c, src/parse-gram.h: Regenerate with 1.875d.
+
+	* configure.ac (--enable-gcc-warnings): Do not enable -Wshadow,

+	lalr1.cc runs afoul of the first, and the last two are no longer
+	supported by GCC 3.4.0.
+	* README: Mention GNU m4 1.4 or later; mention m4 patches.

+
+2004-04-28  Paul Eggert  <eggert@twinsun.com>
+
+	Get files from the gnulib and po repositories, instead of relying

+	* bootstrap: Bootstrap from gnulib and po repositories.
+	Much of this code was stolen from GNU diff and GNU tar's bootstrap.
+	* README-cvs: Document these changes.  Remove version numbers from
+	mentions of build tools, since they change so often.  Mention Flex.
+
+	* configure.ac (AC_CONFIG_MACRO_DIR): Add, with m4 as arg.
+	(gl_USE_SYSTEM_EXTENSIONS): Add.
+	(AC_GNU_SOURCE, AC_AIX, AC_MINIX):
+	Remove; no longer needed, as gl_USE_SYSTEM_EXTENSIONS
+	does this for us.
+	(AC_ISC_POSIX): Remove; we no longer support this
+	ancient OS, as it gets in the way of latest Autoconf & gnulib.
+	(AC_HEADER_STDC): Remove: we now assume C89 or better.
+	(AC_CHECK_HEADERS_ONCE): Use instead of AC_CHECK_HEADERS.
+	Do not check for C89 headers, except for locale.h which is used
