+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+	withdrawn in a future release.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
+	gnulib.
+	* config/install-sh: Sync with autotools.
+
+	Fix a bad interaction with flex 2.5.23 reported by Bruce Lilly in
+	<http://mail.gnu.org/pipermail/bug-bison/2002-November/001929.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.

+	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,

+	Now inline functions rather than macros, to avoid casts.
+	* src/state.h (state_number_as_int): Likewise.
+	* src/tables.c (state_number_to_vector_number,
+	symbol_number_to_vector_number): Likewise.
+
+	* 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):

+	hash_symbol_hasher): Likewise.
+	* src/uniqstr.c (uniqstr_print_processor): Likewise.
+	* src/muscle_tab.c (muscles_m4_output):
+	Use new functions instead of casting old functions unportably.
+	* src/state.c (state_hash_new): Likewise.
+	* src/symtab.c (symbols_new, symbols_do, symbols_check_defined,
+	symbols_token_translations_init):
+	Likewise.
+	* src/uniqstr.c (uniqstrs_new, hash_initialize, uniqstrs_do): 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/state.c (state_hash): Use unsigned accumulator, not signed.
+
+	* src/symtab.c (symbol_free): Remove; unused.
+	(symbol_get): Remove cast in lhs of assignment.
+	(symbols_do): Now static.  Accept generic arguments, not
+	hashing-related ones.
+
+	* src/symtab.h: (NUMBER_UNDEFINED): Remove unnecessary cast.
+	(symbol_processor): Remove.
+	(symbols_do): Remove decl; now static.
+
+	* src/system.h (alloca): Remove; decl no longer needed.
+	(<stddef.h>): Include, for offsetof.
+	(<inttypes.>, <stdint.h>): Include if available.
+	(uintptr_t): New type, if system lacks it.
+	(CALLOC, MALLOC, REALLOC): New macros.
+	All uses of XCALLOC, XMALLOC, and XREALLOC changed to use these
+	new macros.
+
+	* 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.
+	(default_goto, goto_actions, pack_vector): Remove unnecessary casts.
+	* src/uniqstr.c (hash_compare_uniqstr):  Likewise.
+
+	* src/vcg.h: Correct misspellings.
+
+	* src/vcg_defaults.h (G_CMAX): Now INT_MAX.
+
+
+	* src/getargs.c (getargs): Don't assume EOF == -1.
+
+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.
+	* src/uniqstr.h (uniqstr): Renamed from uniqstr_t, which in
+	turn was just renamed from struniq_t.
+	* src/uniqstr.c (uniqstr_processor): Renamed from struniq_processor,
+	which in turn was just renamed from struniq_processor_t.

+	Rename value_t -> value.
+	* 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

+	(ACTION_MAX): Remove; unused.
+	(ACTION_NUMBER_MINIMUM): Renamed from ACTION_MIN.
+	Unnecessary casts removed from above defines.
+
+
+	Fix misspelling in names.
+	* src/vcg.h (enum_alignment_e): Renamed from enum_alignement_e.
+	* src/vcg_defaults.h (G_NODE_ALIGNMENT): Renamed from
+	G_NODE_ALIGNEMENT.
+
+
+	* lib/timevar.c (timevar_report): Renamed from time_report,
+	for consistency with other names.
+	* lib/timevar.h (timevar_report): New decl.
+	* src/system.h (time_report): Remove; decl is now in lib/timevar.h.
+
+
+	Sort include-file uses.
+
+	Reorder all include files under src to be in the order "system.h".
+	then the ../lib include files in angle brackets (alphabetized),
+	then the . include files in double-quotes (alphabetized).  Fix
+	dependency breakages encountered in this process, as follows:
+	* src/closure.h, src/derives.h, src/state.h: Include "gram.h".
+	* src/complain.c: Don't include stdlib.h, string.h _LIBC stuff.
+	* src/state.h: Include "symtab.h".
+
+2002-12-08  Paul Eggert  <eggert@twinsun.com>
+
+	* 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
+	reported by Martin Mokrejs in
+	<http://mail.gnu.org/pipermail/bug-bison/2002-December/001945.html>.
+
+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.
+	(LOCATION_RESET, LOCATION_STEP): Remove.
+	(LOCATION_PRINT): Remove.  All callers changed to use location_print.

+	rolling our own.
+	* src/scan-gram.l (YY_USER_INIT): Initialize scanner_cursor instead
+	of *loc.
+	(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
+	*loc and adjusts the scanner cursor.  All uses changed.
+	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
+	comment, not location.  All callers changed.  Update scanner cursor,
+	not the location.
+	(SC_AFTER_IDENTIFIER): New state.
+	(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.
+	(<SC_YACC_COMMENT>, <SC_COMMENT>, <SC_LINE_COMMENT>):

+	Return correct token start.
+	(<SC_BRACED_CODE,SC_PROLOGUE,SC_EPILOGUE>): Save start boundary when
+	the start of a character, string or multiline comment is found.
+	* tests/conflicts.at (S/R in initial, Defaulted Conflicted
+	Reduction): Adjust reported locations to match the more-precise
+	results now expected.
+	* tests/input.at (Invalid $n, Invalid @n, Type Clashes): Likewise.
+	* tests/reduce.at (Useless Rules, Reduced Automaton,
+	Underivable Rules): Likewise.
+	* tests/regression.at (Invalid inputs): No longer `expecting ";"
+	or "|"' now that so many other tokens are allowed by the new grammar.
+
+	* 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.

+	* 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
+	<http://mail.gnu.org/pipermail/bug-bison/2002-December/001944.html>.
+
+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,
+	to avoid collision with lex macro described by Bruce Lilly in
+	<http://mail.gnu.org/pipermail/bug-bison/2002-November/001929.html>.
+	* tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise.
+	* doc/bison.texinfo (Prologue, Tracing): yyprint -> print_token_value.
+	* 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.
+	(STRING_FREE): Renamed from YY_OBS_FREE.  All uses changed.
+
+	* src/parse-gram.y (gram_error): loc is now const *.
+	* src/reader.h (gram_error): Likewise.
+
+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>
+

+
+2002-11-20  Paul Eggert  <eggert@twinsun.com>
+
+	Avoid use of <assert.h>, as the GNU Coding Standards hint that one
+	should use `if (! x) abort ();' rather than `assert (x);', and
+	anyway it's one less thing to worry about configuring.
+
+	* data/glr.c, lib/hash.c, src/system.h: Do not include <assert.h>.
+	* tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise,

+	* src/getargs.c (trace_argmatch, report_argmatch): Use verify
+	rather than assert.
+	* src/tables.c (tables_generate): Likewise.

+
+2002-11-18  Paul Eggert  <eggert@twinsun.com>
+
+	* data/glr.c (yygetLRActions): Replace `yyindex' with
+	`yytable[yyindex]' to fix typo introduced in my 2002-11-09 patch.
+	This fixes the regression with Sun ONE Studio 7 cc that I reported in
+	<http://mail.gnu.org/pipermail/bug-bison/2002-November/001892.html>.
+
+2002-11-18  Akim Demaille  <akim@epita.fr>
+
+	* doc/bison.texinfo (Tracing): `yyprint' shouldn't prepend a
+	space.
+	From Tim Van Holder.
+
+2002-11-17  Paul Eggert  <eggert@twinsun.com>
+
+	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.
+	(yymergeOptionSets, yyresolvStack): Use `continue;' for empty
+	loop body.
+	(yyreportSyntaxError): Renamed from yyreportParseError.
+	(yyrecoverSyntaxError): Renamed from yyrecoverParseError.
+	All uses changed.
+	* tests/calc.at (_AT_DATA_CALC_Y): Make vars static instead of
+	extern when possible.  Remove unused initializations.
+
+2002-11-16  Akim Demaille  <akim@epita.fr>
+
+	Augment the similarity between GLR and LALR traces.
+
+	* data/yacc.c (yy_stack_print, YY_STACK_PRINT, yy_reduce_print)
+	(YY_REDUCE_PRINT): New.
+	(yyparse): Use them.
+	* data/glr.c (yy_reduce_print): Use YYFPRINTF, no need for
+	YYDPRINT here.
+	(yyglrReduce, yyrecoverParseError, yyparse): Don't report the
+	state reached after the reduction/recovery, since...
+	(yyparse, yyprocessOneStack): Report the state we are entering in.
+
+2002-11-16  Akim Demaille  <akim@epita.fr>
+
+	* src/getargs.h, src/getargs.c (trace_e, trace_args, trace_types):
+	Add support for --trace=skeleton.
+	* src/scan-skel.l: %option debug.
+	Scan strings of non-@ or \n instead of character by character.
+	(scan_skel): Handle trace_skeleton.
+	(QPUTS): New.
+	(@output_parser_name@, @output_header_name@): ``Restore'' their
+	support (used to be M4 macros).
+	* data/yacc.c: Quote larger chunks, a la glr.c.
+	* data/lalr1.cc: Likewise.
+	The header guards are no longer available, so use some other
+	string than `YYLSP_NEEDED'.
+
+2002-11-16  Akim Demaille  <akim@epita.fr>
+
+	Make the ``Printers and Destructors'' test more verbose, taking
+	`yacc.c''s behavior as (possibly wrong) reference.
+
+	* tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Use printf
+	instead of fprint on stdout.
+	Set and report the last_line of the symbols.
+	Consistently display values and locations.
+
+2002-11-16  Paul Eggert  <eggert@twinsun.com>
+
+	* data/yacc.c: Avoid over-quoting of __line__ and __file__.
+
+2002-11-15  Paul Eggert  <eggert@twinsun.com>
+
+	* tests/actions.at (Actions after errors): New test case.
+
+	* data/glr.c, data/lalr1.cc, data/yacc.cc, doc/bison.texinfo,
+	src/conflicts.c, src/parse-gram.y, src/tables.c, src/tables.h,
+	tests/action.at, tests/calc.at, tests/conflicts.at,
+	tests/cxx-type.at, tests/regression.at:
+	"parse error" -> "syntax error" for POSIX compatibility.
+	"parsing stack overflow..." -> "parser stack overflow" so
+	that code matches Bison documentation.
+
+2002-11-15  Akim Demaille  <akim@epita.fr>
+
+	* src/parse-gram.y (declaration): Have %parse-param and %lex-param
+	take two BRACED_CODE, not two string_content.
+	Free the scanner's obstack when we are done.
+	(code_content): New.
+	* tests/calc.at: Adjust.
+	* doc/bison.texinfo: Adjust.
+	Also, make sure to include the `,' for these declarations.
+
+2002-11-15  Tim Van Holder  <tim.van.holder@pandora.be>
+
+	* m4/prereq.m4: Removed the commented jm_PREREQ_HASH
+	definition; avoids potential autoreconf problems.
+
+2002-11-15  Akim Demaille  <akim@epita.fr>
+
+	Always check the value returned by yyparse.
+
+	* tests/calc.at (_AT_DATA_CALC_Y): Have `main' exit with the value
+	returned by yyparse.
+	(_AT_CHECK_CALC_ERROR): Take the expected exit value as argument.
+	Adjust calls.
+	* tests/glr-regr1.at (glr-regr1.y): Have `main' exit with the value
+	returned by yyparse.
+
+2002-11-14  Paul Hilfinger  <Hilfinger@CS.Berkeley.EDU>
+
+	* data/glr.c (yyFail): Always set yyerrflag.  Corrects regression
+	on input.at test.
+
+2002-11-14  Paul Eggert  <eggert@twinsun.com>
+
+	* 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/pipermail/bug-bison/2002-November/001893.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.  This should fix
+	the input.at bug reported by Nelson H. F. Beebe in
+	<http://mail.gnu.org/pipermail/bug-bison/2002-November/001893.html>.
+
+2002-11-14  Akim Demaille  <akim@epita.fr>
+
+	* tests/synclines.at (AT_SYNCLINES_COMPILE): Ignore the exit
+	status of the compiler.
+	Calling `exit 1' is no longer needed.
+	Reported by Nelson H. F. Beebe.
+
+2002-11-14  Akim Demaille  <akim@epita.fr>
+
+	* tests/atlocal.in (CPPFLAGS): We have config.h.
+	* tests/testsuite.at (AT_DATA_GRAMMAR_PROLOGUE, AT_DATA_GRAMMAR):
+	New.

+	* tests/cxx-type.at, tests/glr-regr1.at, tests/headers.at,
+	* tests/regression.at, tests/torture.at: Use them for all the
+	grammars that are to be compiled.
+	* tests/cxx-type.at (_AT_TEST_GLR_CALC): Rename as...
+	* tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): this.
+	* doc/bison.texinfo (GLR Parsers): Document `inline'.
+
+2002-11-14  Akim Demaille  <akim@epita.fr>
+
+	* doc/bison.texinfo: Various formatting changes (alignments in
+	samples, additional @group/@end group, GCS in samples.
+	Use @deffn instead of simple @table to define the directives,
+	macros, variables etc.
+
+2002-11-13  Paul Eggert  <eggert@twinsun.com>
+
+	Fix some bugs reported by Albert Chin-A-Young in
+	<http://mail.gnu.org/pipermail/bug-bison/2002-November/001881.html>.
+
+	* tests/input.at (Torturing the Scanner): Don't invoke "cc a.c b.c
+	-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>
+
+	* data/yacc.c: Leave bigger chunks of quoted text.
+	(YYDSYMPRINTF): New.
+	Use it to report symbol activities.
+	* data/glr.c (YYDSYMPRINTF): New.
+	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/pipermail/bug-bison/2002-November/001872.html>.
+
+	* lib/bbitset.h (BITSET_INLINE): Remove.
+	* lib/bitset.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/pipermail/bug-bison/2002-November/001873.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/pipermail/bison-patches/2002-November/001352.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.
+	* src/struniq.c (struniq_new): Likewise.
+
+2002-11-12  Albert Chin-A-Young <china@thewrittenword.com>
+
+	* src/Makefile.am (LDADD): Link $(LIBINTL) last to avoid the

+
+2002-11-12  Akim Demaille  <akim@epita.fr>
+
+	* tests/regression.at (input.y): s/YYEOF/MYEOF/, as the skeleton

+	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
+	instead of CPP macros.
+	Don't rely on internal details.

+2002-11-12  Akim Demaille  <akim@epita.fr>
+
+	* 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 against YYEMPTY and so forth), work on yytoken (i.e., set
+	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.

+
+	* doc/bison.texinfo (Destructor Decl): New.
+
+2002-11-12  Akim Demaille  <akim@epita.fr>
+
+	* src/tables.c (tables_generate): Use free for pointers that

+2002-11-12  Akim Demaille  <akim@epita.fr>
+
+	* src/scan-gram.l, src/reader.h (scanner_last_string_free):
+	Restore.
+	* src/scan-gram.l (last_string): Is global to the file, not to

+	* src/files.h, src/files.c (infile): Split into...
+	(grammar_file, current_file): these.
+	* src/scan-gram.c (YY_USER_INIT, handle_syncline): Adjust.
+	* src/reduce.c (reduce_print): Likewise.
+	* src/getargs.c (getargs): Likewise.
+	* src/complain.h, src/complain.c: Likewise.
+	* src/main.c (main): Call struniqs_new early enough to use it for

+	Don't free the input file name.
+
+2002-11-12  Akim Demaille  <akim@epita.fr>
+
+	* src/symtab.c (symbol_free): Remove dead deactivated code:

+
+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/pipermail/bison-patches/2002-November/001329.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/pipermail/bug-bison/2002-November/001815.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.
+
+2002-11-07  Akim Demaille  <akim@epita.fr>
+

+	(symbol_destructors_output): Quote the file name.
+
+2002-11-06  Akim Demaille  <akim@epita.fr>

+	* src/reader.c (prologue_augment, epilogue_set): Use b4_syncline.
+	* src/output.c (user_actions_output): Likewise.
+	(prepare): Define 'b4_synclines_flag'.

+
+2002-11-06  Akim Demaille  <akim@epita.fr>
+
+	* src/main.c (main): Free `infile'.
+	* src/scan-gram.l (handle_syncline): New.

+	* src/output.c (user_actions_output, symbol_destructors_output)
+	(symbol_printers_output): Use the location's file name, not
+	infile.
+	* src/reader.c (prologue_augment, epilogue_set): Likewise.
+
+2002-11-05  Paul Hilfinger  <Hilfinger@CS.Berkeley.EDU>
+
+	* src/tables.c (matching_state): Don't allow states to match if
+	either has GLR conflict entries.
+
+2002-11-05  Paul Eggert  <eggert@twinsun.com>
+
+	* src/scan-gram.l: Use more accurate diagnostics, e.g.
+	"integer out of range" rather than "invalid value".
+	* 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.
+	(INITIAL): Clear braces_level instead of incrementing it.
+	(SC_BRACED_CODE): Treat <% and %> as { and } when inside C code,
+	as POSIX 1003.1-2001 requires.
+	* src/system.h (IF_LINT): New macro, taken from coreutils.
+	* configure.ac: Define "lint" if --enable-gcc-warnings.
+
+2002-11-05  Akim Demaille  <akim@epita.fr>
+
+	* src/scan-gram.l: When it starts with `%', complain about the
+	whole directive, not just that `invalid character: %'.
+
+2002-11-04  Akim Demaille  <akim@epita.fr>
+
+	* Makefile.maint: Update from Autoconf.

+
+	* tests/glr-regr1.at (Badly Collapsed GLR States): Prototype yylex

+	* tests/calc.at (AT_CHECK_PUSHDEFS): AT_YYERROR_SEES_LOC_IF
+	returns true when location & yacc & pure & parse-param.
+	(_AT_DATA_CALC_Y): Let yyerror ``use'' its arguments.
+
+2002-11-04  Akim Demaille  <akim@epita.fr>
+
+	* src/location.h (LOCATION_PRINT): Use quotearg slot 3 to avoid

+	* src/scan-gram.l: Use [\'] instead of ['] to pacify

+
+2002-11-03  Paul Eggert  <eggert@twinsun.com>
+
+	* src/reader.c (get_merge_function, grammar_current_rule_check):

+	* tests/cxx-type.at: Formatting changes.
+
+2002-11-03  Paul Eggert  <eggert@twinsun.com>
+
+	* src/scan-gram.l: Revamp to fix POSIX incompatibilities,
+	to count columns correctly, and to check for invalid inputs.
+
+	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.

+	(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.

+
+	(letter, id): Don't assume ASCII; e.g., spell out a-z.
+
+	({int}, handle_action_dollar, handle_action_at): Check for integer

+
+	(YY_STEP): Omit trailing semicolon, so that it's more like C.
+
+	(<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER>): Allow \0 and \00

+
+	(handle_symbol_code_dollar): Use quote_n slot 1 to avoid collision

+	* src/output.c (prepare_symbols): When printing token names,

+
+	* src/system.h (errno): Remove declaration, as we are now

+
+2002-10-30  Paul Eggert  <eggert@twinsun.com>
+
+	* lib/bitset_stats.c (bitset_stats_read, bitset_stats_write):
+	Check for close failures.

+	* src/files.c (xfclose): Likewise.  Report I/O error if ferror
+	indicates one.
+	* src/output.c (output_skeleton): Use xfclose rather than fclose
+	and ferror.  xfclose now checks ferror.
+
+	* data/glr.c (YYLEFTMOST_STATE): Remove.
+	(yyreportTree): Use a stack-based leftmost state.  This avoids

+
+2002-10-30  Akim Demaille  <akim@epita.fr>
+
+	* src/system.h: Don't use #ifdef/#ifndef on HAVE_ values, only

+
+2002-10-29  Paul Hilfinger  <Hilfinger@CS.Berkeley.EDU>
+
+	* tests/glr-regr1.at: New test for reported regressions.

+
+2002-10-24  Paul Eggert  <eggert@twinsun.com>
+
+	Version 1.75a.
+
+	* 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

+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>

+
+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/pipermail/bug-bison/2002-October/001764.html
+	http://mail.gnu.org/pipermail/bug-bison/2002-October/001769.html
+	and I hope it also fixes this bug report:
+	http://mail.gnu.org/pipermail/bug-bison/2002-October/001748.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/symtab.c (hash_compare_symbol_t): Likewise.
+	* src/system.h (bool, false, true): Use a definition consistent
+	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/main.c (main): Likewise.
+	* src/getargs.c (getargs): Likewise.
+	* src/reader.c (reader): Likewise.
+
+	* 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.
+	* src/complain.c (VA_START): Remove.  Assume prototypes.
+	(vfprintf) [! (HAVE_VPRINTF || defined vfprintf)]: New macro.
+	(private_strerror, warn_at, warn, complain_at, complain, fatal_at,
+	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.
