+	local variables whose names begin with 'yy'.
+	* tests/calc.at (_AT_DATA_CALC_Y): Likewise.

+
+	* bootstrap (gnulib_modules): Remove alloca.  Bison doesn't need
+	it itself.
+	* src/main.c (main) [C_ALLOCA]: Don't flush alloca'ed memory; we
+	don't use alloca any more.
+
+	* data/yacc.c [YYSTACK_USE_ALLOCA && !defined __GNUC__ && ! defined

+	(_STDLIB_H): Renamed from YYINCLUDED_STDLIB_H.  All uses changed.
+	This works a bit better with glibc, if user code has already included
+	stdlib.h.
+	* doc/bison.texinfo (Bison Parser): Document that users can't
+	arbitrarily use malloc and free for other purposes.  Document
+	that <alloca.h> and <malloc.h> might be included.
+	(Table of Symbols): Under YYSTACK_USE_ALLOCA, Don't claim that the
+	user must declare alloca.

+	(yysyntax_error): New function.
+	(yyparse) [YYERROR_VERBOSE]: Don't leak memory indefinitely if
+	multiple syntax errors are reported, and alloca is being used.
+	Instead, reallocate buffers twice as big each time, so that
+	we waste at most half the allocated memory.  Start with a small
+	(128-byte) buffer that will suffice in most cases anyway.
+	Use yysyntax_error to do most of the work.
+
+	* doc/bison.texinfo (Error Reporting, Table of Symbols):
+	yynerrs is the number of errors reported, not the number of
+	errors encountered.
+
+	* tests/glr-regression.at (Duplicated user destructor for lookahead):
+	Mark it as expected to fail.
+	Cast result of malloc; problem reported by twlevo@xs4all.nl.
+	* tests/actions.at, tests/calc.at, tests/glr-regression.at:
+	Don't start user-code symbols with "yy", to avoid name space problems.
+
+2005-09-19  Akim Demaille  <akim@epita.fr>
+
+	Remove the traits, failed experiment.
+	It never proved useful, and anyway because of the current
+	definition, it was not possible to have several specialization of
+	this traits, making it useless.
+	* data/lalr1.cc (yy:traits): Remove.
+	Inline its definitions in the parser class.
+
+2005-09-19  Akim Demaille  <akim@epita.fr>

+	* data/lalr1.cc (YYERROR_VERBOSE_IF): New macro.

+	is not defined.  This is an awful hack, but it's enough for now.
+	All callers changed.
+	* tests/glr-regression-at (make_value): Args are const pointers now,
+	to avoid GCC warning.
+	(Duplicated user destructor for lookahead): New test.  Currently
+	skipped.  It fails on my host but I'm not sure it'll always fail.
+
+2005-09-16  Akim Demaille  <akim@epita.fr>
+
+	* src/symtab.h (struct symbol): Declare the printer and destructor
+	as const, to avoid accidental calls to free.
+	(symbol_destructor_set, symbol_printer_set): Adjust.
+	* src/symtab.c: Adjust.
+
+2005-09-16  Akim Demaille  <akim@epita.fr>

+
+2005-09-16  Akim Demaille  <akim@epita.fr>
+
+	* data/lalr1.cc (yylex_): Remove, inline its code.
+	(yyreport_syntax_error_): Remove, replaced by...
+	(yysyntax_error_): this which returns a string and leaves to the
+	caller the call to the users' error function.
+	(yylooka_, yyilooka_, yylval, yylloc, yyerror_range_, yyval, yyloc):
+	Move from members of the parser object...
+	(yylooka, yyilooka, yylval, yylloc, yyerror_range, yyval, yyloc):
+	to local variables of the parse function.
+
+2005-09-16  Akim Demaille  <akim@epita.fr>
+
+	* doc/bison.texinfo (Calc++ Parser): Don't promote defining YYEOF
+	since it's in Bison's name space.
+
+2005-09-15  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* data/glr.c (yyresolveValue): Add default case to pacify

+
+2005-09-14  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* examples/calc++/Makefile.am ($(calc_sources_generated)): Don't
+	do anything if $@ exists.  This reverts part of the 2005-07-07
+	patch.
+
+2005-09-11  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* Makefile.am (EXTRA_DIST): Do not distribute REFERENCES; it
+	contains obsolete information and isn't worth distributing as a
+	separate file anyway.
+	* data/glr.c [defined YYSETJMP]: Don't include <setjmp.h>.
+	(YYJMP_BUF, YYSETJMP, YYLONGJMP) [!defined YYSETJMP]: New macros.

+	(yyparse): Abort if user code uses longjmp to throw an unexpected
+	value.
+
+2005-09-09  Paul Eggert  <eggert@cs.ucla.edu>

+	Suggested by twlevo@xs4all.nl.

+	This avoids a diagnostic from gcc -Wswitch-enum.
+	Problem reported by twlevo@xs4all.nl.
+
+	* doc/bison.texinfo: Don't use "filename", as per GNU coding
+	standards.  Use "file name" or "file" or "name", depending on

+
+2005-08-21  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* lib/.cvsignore: Remove realloc.c, strncasecmp.c, xstrdup.c.

+	lib-prefix.m4, po.m4.
+
+	* data/glr.c (yyreturn): Use "Cleanup:" rather than "Error:"
+	in yydestruct diagnostic, since it might not be an error.
+	Problem reported by Joel Denny near end of
+	<http://lists.gnu.org/archive/html/help-bison/2005-07/msg00040.html>.
+	* data/lalr1.cc (yyerturn): Likewise.
+	* data/yacc.c (yyreturn): Likewise.

+
+	* src/files.c: Remove obsolete FIXME comment.
+

+	New test, from Joel E. Denny in:
+	<http://lists.gnu.org/archive/html/help-bison/2005-07/msg00013.html>.
+	* THANKS: Add Joel E. Denny.
+
+	* configure.ac (AC_INIT): Bump to 2.0c.
+
+2005-07-24  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* NEWS: Version 2.0b.
+
+	* Makefile.am (SUBDIRS): Put examples before tests, so that
+	"make check" doesn't finish with "All 1 tests passed".
+
+	* tests/regression.at (Token definitions): Don't rely on
+	AT_PARSER_CHECK for data that contains backslashes.  It currently
+	uses 'echo', and 'echo' isn't portable if its argument contains
+	backslashes.  Problem found on OpenBSD 3.4.  Also, do not assume
+	that the byte '\0xff' is not printable in the C locale; it is,
+	under OpenBSD 3.4 (!).  Luckily, '\0x80' through '\0x9e' are
+	not printable, so use '\0x81' to test.
+
+	* data/glr.c (YYOPTIONAL_LOC): Define even if it's not a recent
+	version of GCC, since the macro is used with non-GCC compilers.
+
+	Fix core dump reported by Pablo De Napoli in
+	<http://lists.gnu.org/archive/html/bug-bison/2005-07/msg00053.html>.
+	* tests/regression.at (Invalid inputs with {}): New test.
+	* src/parse-gram.y (token_name): Translate type before using
+	it as an index.
+
+	* data/glr.c (ATTRIBUTE_UNUSED): Remove, since it infringes on
+	the user's name space.  All uses changed to __attribute__
+	((__unused__)).
+	(yyFail, yyMemoryExhausted, yyreportAmbiguity):
+	Add __attribute__ ((__noreturn__)).
+
+	* etc/clcommit: Remove.  We weren't using it, and it failed
+	"make maintainer-distcheck".
+	* Makefile.maint: Merge from coreutils.
+	(CVS_LIST, CVS_LIST_EXCEPT): New macros.
+	(syntax-check-rules): Change list of rules as described below.
+	(sc_cast_of_alloca_return_value, sc_dd_max_sym_length):
+	(sc_file_system, sc_obsolete_symbols, sc_prohibit_atoi_atof):
+	(sc_prohibit_jm_in_m4, sc_root_tests, sc_tight_scope):
+	(sc_trailing_space): New rules.
+	(sc_xalloc_h_in_src): Remove.
+	(sc_cast_of_argument_to_free, sc_cast_of_x_alloc_return_value):
+	(sc_space_tab, sc_error_exit_success, sc_changelog):
+	(sc_system_h_headers, sc_sun_os_names, sc_unmarked_diagnostics):
+	(makefile-check, po-check, author_mark_check):
+	(makefile_path_separator_check, copyright-check):
+	Use grep -n, to make it easier to find violations.
+	Use CVS_LIST and CVS_LIST_EXCEPT.
+	(header_regexp, h_re): Remove.
+	(dd_c): New macro.
+	(sc_dd_max_sym_length, .re-list, news-date-check): New rules.
+	(my-distcheck): Use more-modern GCC flags.
+	(signatures, %.asc): Remove.
+	(rel-files, announcement): Remove signatures.
+	Restore old updating code, even though we don't use it, so
+	that we're the same as coreutils.
+	(alpha, beta, major): Depend on news-date-check.
+	Make the upload commands.
+
+	* data/c.m4, data/lalr1.cc, data/yacc.c: Normalize white space.
+	* lib/abitset.h, lib/bbitset.h, lib/bitset.h: Likewise.
+	* lib/bitset_stats.c, lib/ebitset.h, lib/lbitset.c: Likewise.
+	* lib/libitset.h, lib/timevar.c, lib/vbitset.h: Likewise.
+	* src/Makefile.am, src/gram.c, src/muscle_tab.h: Likewise.

+	* src/vcg_defaults.h, tests/cxx-type.at, tests/existing.at: Likewise.
+	* tests/sets.at: Likewise.
+
+	* data/m4sugar/m4sugar.m4: Sync from Autoconf, except that
+	we comment out the Autoconf version number.
+	* doc/bison.texinfo (Calc++ Scanner): Don't use atoi, as
+	it's error-prone and "make maintainer-distcheck" rejects it.
+
+	* lib/subpipe.c: Include <fcntl.h> without checking for HAVE_FCNTL_H.
+	Indent calls to "error" to pacify "make maintainer-distcheck",
+	when the calls are not intended to be translated.
+	* m4/subpipe.m4 (BISON_PREREQ_SUBPIPE): Don't check for fcntl.h.
+
+	* src/Makefile.am (DEFS): Use +=, to pacify
+	"make maintainer-distcheck".
+	(bison_SOURCES): Add scan-skel.h.
+	(sc_tight_scope): New rule, from coreutils.
+
+	* src/files.c (src_extension, header_extension):
+	Now static, not extern.
+	* src/getargs.c (short_options): Likewise.
+	* src/muscle_tab.c (muscle_table): Likewise.
+	* src/parse-gram.y (current_class, current_type, current_prec):
+	Likewise.
+	* src/reader.c (grammar_end, previous_rule_end): Likewise.
+	* src/getargs.h: Redo comments to pacify "make maintainer-distcheck".
+	* src/main.c (main): Cast bindtextdomain and textdomain calls to
+	void, to avoid warning when NLS is disabled.
+	* src/output.c: Include scan-skel.h.
+	(scan_skel): Remove decl, since scan-skel.h does this.

+

+	not @VAR@.
+
+	* tests/torture.at: Revamp to avoid misuse of atoi that
+	"make maintainer-distcheck" complained about.
+
+	* examples/extexi (message): Don't print a message more than once,
+	and omit line-number decoration that makes Emacs compile think
+	that informative messages are worth worrying about.
+
+2005-07-22  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* configure.ac: Update version number.
+
+	* Makefile.am (SUBDIRS): Add examples; somehow this got removed
+	accidentally.
+	* examples/calc++/calc++-parser.yy: Remove from CVS, as it's
+	autogenerated by the maintainer.
+	* examples/calc++/.cvsignore: Add *.yy.
+
+	* lib/bitset.c (bitset_alloc): Don't cast xcalloc result.
+	* lib/bitset_stats.c (bitset_stats_init): Likewise.
+	* lib/bitsetv.c (bitsetv_alloc): Likewise.
+
+	* po/POTFILES.in: Add lib/xalloc-die.c; remove lib/xmalloc.c.
+
+	* src/relation.c (relation_transpose): Rewrite to avoid bogus complaint
+	from maintainer-distcheck about casting the argument of 'free'.
+
+	* NEWS: Mention recent yytname changes.
+	* THANKS: Add Anthony Heading, twlevo@xs4all.nl.
+
+	* bootstrap: For translations that have not yet been upgraded to
+	the new runtime-po domain, prime the pump by extracting the
+	relevant strings from the obsolete translations.  This code can be
+	removed once the bison-runtime domain has been translated by each
+	team.
+
+	* src/scan-gram.l (<SC_PRE_CODE>.): Don't double-quote token names,
+	now that token names are already quoted.
+
+	Fix problem reported by Anthony Heading.
+	* data/glr.c (YYTOKEN_TABLE): New macro.
+	(yytname): Define if YYTOKEN_TABLE.
+	* data/yacc.c (YYTOKEN_TABLE, yytname): Likewise.
+	* data/lalr1.cc (YYTOKEN_TABLE, yytname_): Likewise.
+	(YYERROR_VERBOSE): Define the same way the other skeletons do.
+	* src/output.c (prepare_symbols): Output token_table_flag.
+
+2005-07-21  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* data/glr.c (yyinitGLRStack, yyreturn): Don't call malloc
+	again if the first call fails.
+
+	* data/glr.c (yytnamerr): New function.
+	(yyreportSyntaxError): Use it to dequote most string literals.
+	* data/lalr1.c (yytname_): Renamed from yyname_, for compatibility
+	with other skeletons.  All uses changed.
+	(yytnameerr_): New function.
+	(yyreport_syntax_error): Use it to dequote most string literals.
+	* data/yacc.c (yytnamerr): New function.
+	(yyerrlab): Use it to decode most string literals.
+	* doc/bison.texinfo (Decl Summary, Calling Convention):
+	Clarify quoting convention of yytname.
+	* src/output.c (prepare_symbols): Quote all names.  This undoes
+	the 2005-04-17 change, which is now accomplished (mostly) via
+	changes in the parsers as described above.
+	* tests/regression.at (Token definitions, Web2c Actions):
+	Undo most 2005-04-17 change here, too.
+
+2005-07-20  Paul Eggert  <eggert@cs.ucla.edu>
+
+	Fix more problems reported by twlevo@xs4all.nl.
+	* tests/cxx-type.at: Don't pipe output of ./types through sed to
+	remove trailing spaces.  This loses the exit status of ./types,
+	and isn't needed since ./types shouldn't be emitting trailing
+	spaces.
+	* data/glr.c (yyreturn): Don't pop stack if yyinitStateSet failed,
+	as the stack isn't valid in that case.
+
+	* src/scan-gram.l (gram_get_lineno, gram_get_in, gram_get_out):
+	(gram_get_leng, gram_get_text, gram_set_lineno, gram_set_in):
+	(gram_set_out, gram_get_debug, gram_set_debug, gram_lex_destroy):
+	Add declarations to pacify "gcc -Wmissing-prototypes" when flex 2.5.31
+	is used.
+	* src/scan-skel.l (skel_get_lineno, skel_get_in, skel_get_out):
+	(skel_get_leng, skel_get_text, skel_set_lineno, skel_set_in):
+	(skel_set_out, skel_get_debug, skel_set_debug, skel_lex_destroy):
+	Likewise.
+
+	* tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Work even with
+	overly-picky compilers that reject 'char *foo = "bar";'.
+
+	* src/symtab.c (SYMBOL_ATTR_PRINT, symbol_print): Direct output
+	to FILE * parameter, not to stderr.  This fixes a typo introduced
+	in the 2005-07-12 change.
+
+	* lib/subpipe.c (create_subpipe): Rewrite slightly to avoid
+	warnings from GCC 4.
+
+	* data/glr.c (yyexpandGLRStack, yyaddDeferredAction, yyexpandGLRStack):
+	(yyglrShiftDefer, yysplitStack):
+	Remove unused parameters b4_pure_formals.  All uses changed.
+	(yyglrShift): Remove unused parameters b4_user_formals.
+	All uses changed.
+	(yyglrReduce): Removed unused parameter yylocp.  All uses changed.
+
 2005-07-18  Paul Eggert  <eggert@cs.ucla.edu>
 
+	Destructor cleanups and regularization among the three skeletons.
+	* NEWS: Document the behavior changes.
+	* data/glr.c (yyrecoverSyntaxError): Don't bother to pop the
+	stack before failing, as the cleanup code will do it for us now.
+	* data/lalr1.cc (yyerrlab): Likewise.
+	* data/glr.c (yyparse): Pop everything off the stack before
+	freeing it, so that destructors get called properly.
+	* data/lalr1.cc (yyreturn): Likewise.
+	* data/yacc.c (yyreturn): Pop and destroy the start symbol, too.
+	This is more consistent.
+	* doc/bison.texinfo (Destructor Decl): Mention more reasons
+	why destructors might be called.  1.875 -> 2.1.
+	(Destructor Decl, Decl Summary, Table of Symbols):
+	Some English-language cleanups for %destructor.
+	* tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
+	Add output line for destructor of start symbol.
+	* tests/calc.at (AT_CHECK_CALC): Add one to line counts,
+	because of that same extra output line.
+
+	* NEWS: Document minor wording changes in diagnostics of
+	Bison-generated parsers.
+	* data/glr.c (yyMemoryExhausted): Renamed from yyStackOverflow.
+	Remove unused formals.  All uses changed.
+	(yyreportAmbiguity): "ambiguity detected" -> "syntax is ambiguous".
+	(yyparse): Rename yyoverflowlab to yyexhaustedlab.
+	* data/yacc.c (yyparse): "parser stack overflow" -> "memory exhausted".
+	Rename yyoverflowab to yyexhaustedlab.
+	When memory exhaustion occurs during syntax-error reporting,
+	report it separately rather than in a single diagnostic; this
+	eases translation.
+	* doc/bison.texinfo (Memory Management): Renamed from Stack Overflow.
+	(Memory Exhausted): Renamed from Parser Stack Overflow.
+	Revamp wording slightly to prefer "memory exhaustion".
+	* tests/actions.at: "parser stack overflow" -> "memory exhausted".
+
+	* data/c.m4 (b4_yysymprint_generate): Use YYFPRINTF, not fprintf.
+
 	Add i18n support to the GLR skeleton.  Partially fix the C++
 	skeleton; a C++ expert needs to finish this.  Remove debugging
