+2006-05-19  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* NEWS: Version 2.2.
+	* configure.ac (AC_INIT): Likewise.
+
+2006-05-17  Joel E. Denny  <jdenny@ces.clemson.edu>
+
+	* data/glr.c (yyreportTree): Make room in yystates for the state
+	preceding the RHS.  This fixes the segmentation fault reported by Derek
+	M. Jones in
+	<http://lists.gnu.org/archive/html/help-bison/2006-05/msg00035.html>.
+	(yyreportTree, yypdumpstack): Subtract 1 from yyrule before printing
+	to the user.  Reported for yyreportTree by Derek M. Jones later in the
+	same thread.
+	* THANKS: Add Derek M. Jones.
+	Update my email address.
+	Fix typo in Steve Murphy's name.
+
+2006-05-14  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* data/glr.c (yyreportSyntaxError): Fix off-by-one error in
+	checking against YYLAST that caused the parser to miss a potential
+	alternative in its diagnostic.
+	Problem reported by Maria Jose Moron Fernandez in
+	<http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00024.html>.
+	* data/lalr1.cc (yysyntax_error_): Likewise.
+	* data/yacc.c (yysyntax_error): Likewise.
+	* tests/regression.at (_AT_DATA_DANCER_Y): Use static array for
+	tokens, in case we run into an older C compiler.
+	(_AT_DATA_EXPECT2_Y, AT_CHECK_EXPECT2): New macros.
+	Use them to check for the off-by-one error fixed above.
+
+	* data/yacc.c (yytnamerr): Fix typo: local var should be of type
+	YYSIZE_T, not size_t.
+	* tests/regression.at (Trivial grammars): New test, to catch
+	the error fixed by the above patch.
+
+2006-05-14  Akim Demaille  <akim@lrde.epita.fr>
+
+	* doc/bison.texinfo (C++ Bison Interface): Clarify the naming
+	scheme.
+	Reported by Steve Murphy.
+
+2006-05-14  Akim Demaille  <akim@lrde.epita.fr>
+
+	* data/glr.cc, data/lalr1.cc: Using %defines is mandatory.
+	* data/glr.cc: b4_location_flag is now b4_locations_flag.
+
+2006-05-14  Akim Demaille  <akim@lrde.epita.fr>
+
+	Implement --trace=m4.
+	* src/getargs.c (trace_types, trace_args): Accept trace_m4.
+	* src/output.c (output_skeleton): When set, pass -dV to m4.
+
+	Factor the handling of flags in m4.
+	* src/output.c (prepare): Rename the muscle names debug, defines,
+	error_verbose to debug_flag, defines_flag, error_verbose_flag.
+	* data/c.m4: Adjust.
+	(_b4_define_flag_if, b4_define_flag_if, b4_defines_if): New.
+	Use b4_define_flag_if to define other b4_FLAG_if macros.
+	(b4_location_if): As a consequence, rename as...
+	(b4_locations_if): this, for consistency.
+	Adjust all the skeletons.
+
+2006-05-14  Akim Demaille  <akim@lrde.epita.fr>
+
+	* etc/bench.pm: Shorten bench names.
+
+2006-05-14  Akim Demaille  <akim@lrde.epita.fr>
+
+	* src/output.h, src/output.c (error_verbose): Move to...
+	* src/getargs.h, src/getargs.c: here.
+	Sort the flags.
+	Adjust dependencies.
+
+2006-05-13  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* data/c.m4 (b4_copyright): Put the special exception for Bison
+	skeletons here, so we don't have to put it in each skeleton.  All
+	uses changed.  Suggested by Akim Demaille.  Also, wrap the
+	copyright notice, in case it is longer than 80 columns.  Replace
+	comma by newline after title.
+
+2006-05-11  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* doc/bison.texinfo (Calc++ Scanner): The flex behavior is an
+	incompatibility, not a bug.  Mention that it wasn't fixed as of
+	flex 2.5.33.
+
+2006-05-11  Akim Demaille  <akim@lrde.epita.fr>
+
+	* examples/extexi: Enforce the precedence of concatenation over

+	Reported by Tommy Nordgren.
+
+2006-05-11  Akim Demaille  <akim@lrde.epita.fr>
+
+	* data/lalr1.cc (yytranslate_): Rename token as t to avoid clashes
+	with the member "token".
+	Reported by Martin Nylin.
+
+2006-05-08  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* data/glr.c: Switch to Bison 2.2 special-exception language in
+	the copyright notice.  Use more-regular format for titles and
+	copyright notices.
+	* data/glr.cc: Likewise.
+	* data/location.cc: Likewise.
+	* data/yacc.cc: Likewise.
+	* doc/bison.texinfo (Conditions): Document this.
+	* NEWS: likewise.  Upgrade version to 2.2.
+
+2006-04-27  Akim Demaille  <akim@lrde.epita.fr>
+
+	* data/glr.cc: Remove dead code.
+
+2006-04-25  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* bootstrap: Comment out the AM_CPPFLAGS line, since we don't use
+	that variable and the line breaks the bootstrap.  Problem reported
+	by Juan M. Guerrero.
+
+2006-04-24  Akim Demaille  <akim@lrde.epita.fr>
+
+	* doc/bison.texinfo (Multiple start-symbols): New.

+
+	* etc/README, etc/bench.pl: New.
+
+2006-04-03  Akim Demaille  <akim@lrde.epita.fr>
+
+	* src/scan-gram.l: Be robust to BRACED_CODE appearing before any
+	rule.
+	Reported by Mickael Labau.

+
+2006-03-16  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* doc/bison.texinfo (Decl Summary): Don't mention yylloc twice.
+	Problem reported by Bob Rossi.
+
+2006-03-13  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* doc/bison.texinfo: Remove @shorttitlepage stuff; it wasn't used
+	and didn't really work.
+	For the index, use @ifnotinfo, not @iftex.
+	Minor cleanups of spacing and terminology.
+
+2006-03-12  Akim Demaille  <akim@lrde.epita.fr>
+
+	* tests/local.at (_AT_BISON_OPTION_PUSHDEFS): Fix the definition
+	of AT_NAME_PREFIX when %name-prefix is not used.
+
+2006-03-12  Akim Demaille  <akim@lrde.epita.fr>
+
+	Apply --prefix to C++ skeletons too: they change the namespace.
+	The test suite already exercize these cases.
+	* data/c++.m4 (b4_namespace): New.
+	* data/lalr1.cc, data/glr.cc, data/location.cc: Use it instead of `yy'.
+	* data/lalr1.cc (yytnameerr_): Move its definition into the namespace.
+	* data/yacc.c, data/glr.c: Remove a useless `[]'.
+	* doc/bison.texinfo: Document it.
+	(Option Cross Key): Use @multitable in all formats.  It looks
+	nicer, even in TeX outputs.
+	(Rules): Use the same code whatever the output type is.
+	* tests/local.at (_AT_BISON_OPTION_PUSHDEFS)
+	(_AT_BISON_OPTION_POPDEFS): Support AT_NAME_PREFIX.
+	* tests/calc.at: Use it, instead of hard coding `yy'.
+
+2006-03-10  Akim Demaille  <akim@lrde.epita.fr>
+
+	* TODO: Remove dead items.
+
+2006-03-10  Akim Demaille  <akim@lrde.epita.fr>
+
+	* doc/FAQ: Remove, merged into...
+	* doc/bison.texinfo (FAQ): this.
+	* doc/Makefile.am (EXTRA_DIST): Adjust.
+
+2006-03-10  Akim Demaille  <akim@lrde.epita.fr>
+
+	* data/c.m4 (b4_token_enum): Always define the enum of tokens,
+	even if empty.
+	* data/lalrl1.cc, data/glr.cc (parser::token_type): New.
+	* doc/bison.texinfo (Calc++ Scanner): Use it.
+
+2006-03-09  Paul Eggert  <eggert@cs.ucla.edu>
+
+	Fix two nits reported by twlevo, plus one more that I discovered.
+
+	* src/assoc.h (assoc_to_string): Give a name to the arg, as
+	this is the usual Bison style.
+	* src/location.h (location_print): Likewise.
+
+	* src/reader.h (token_name): Likewise.
+
+2006-03-08  Paul Eggert  <eggert@cs.ucla.edu>
+
+	Fix some nits reported by twlevo.
+	* doc/FAQ: Remove ancient Y2K FAQ, replacing it with "secure"
+	and "POSIX".  Use more-modern syntax for URLs.  Mention C++
+	and ask for Java.  Don't hardwire OS version numbers.  Add
+	copyright notice.
+	* m4/.cvsignore: Add unistd_h.m4, for latest gnulib.
+	* src/conflicts.c (solved_conflicts_obstack): Now static.
+
+2006-03-08  Joel E. Denny  <jdenny@ces.clemson.edu>
+
+	* doc/bison.texinfo (Introduction): Mention GLR and C++ as on the web
+	page.  Say "you can use it" not "you may use it" as on the web page;
+	we're describing capabilities not granting permission.
+
+2006-03-06  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* data/glr.c (yyresolveLocations): Rename local variables to avoid
+	shadowing warnings.  Use usual patter for iterating through RHS.
+	* tests/glr-regression.at
+	(Uninitialized location when reporting ambiguity):
+	Modify yylex so that it uses its argument, rather than trying
+	to rely on ARGSUSED (which doesn't work for gcc with warnings).
+	const char -> char const.
+
+	* tests/Makefile.am ($(srcdir)/package.m4, maintainer-check-valgrind):
+	Don't use tabs inside commands; it messes up 'ps'.
+	Problem reported by twlevo.
+
+2006-03-06  Joel E. Denny  <jdenny@ces.clemson.edu>
+
+	* tests/glr-regression.at (Uninitialized location when reporting
+	ambiguity): New test case.
+	* data/glr.c (yyresolveLocations): New function, which uses
+	YYLLOC_DEFAULT.
+	(yyresolveValue): Invoke yyresolveLocations before reporting an
+	ambiguity.
+	* doc/bison.texinfo (Default Action for Locations): Note
+	YYLLOC_DEFAULT's usage for ambiguity locations.
+	(GLR Semantic Actions): Cross-reference those notes.
+
+2006-03-04  Joel E. Denny  <jdenny@ces.clemson.edu>
+
+	* tests/glr-regression.at (Leaked semantic values when reporting
+	ambiguity): Remove unnecessary union and type declarations.
+	(Leaked lookahead after nondeterministic parse syntax error): New test
+	case.
+	* data/glr.c (yyparse): Check for zero stacks remaining before
+	attempting to shift the lookahead so that you don't lose it.
+
+2006-03-02  Joel E. Denny  <jdenny@ces.clemson.edu>
+
+	Avoid memory leaks by not invoking longjmp in yyreportAmbiguity.
+	* tests/glr-regression.at (Leaked semantic values when reporting
+	ambiguity): New test case.
+	* data/glr.c (yyreportAmbiguity): Invoke yyyerror directly and return
+	yyabort rather than invoking yyFail, which invokes longjmp.  Remove the
+	now unnecessary yystackp parameter.
+	(yyresolveValue): Return yyreportAmbiguity's result.  Now the necessary
+	destructors can be called.
+
+	* tests/glr-regression.at: Don't invoke bison with `-t' unnecessarily
+	in existing testcases.
+
+2006-03-02  Joel E. Denny  <jdenny@ces.clemson.edu>
+
+	Don't leak semantic values for parent RHS when a user action cuts the
+	parser, and clean up related code a bit.
+	* tests/glr-regression.at (Leaked merged semantic value if user action
+	cuts parse): Rename to...
+	(Leaked semantic values if user action cuts parse): ... this.  Add check
+	for leaked parent RHS values.
+	* data/glr.c (yydestroyGLRState): In debugging output, distinguish
+	between an unresolved state (non-empty chain of semantic options) and
+	an incomplete one (signaled by an empty chain).
+	(yyresolveStates): Document the interface.  Move all manipulation of a
+	successfully or unsuccessfully resolved yyGLRState to...
+	(yyresolveValue): ... here so that yyresolveValue always leaves a
+	yyGLRState with consistent data and thus is easier to understand.
+	Remove the yyvalp and yylocp parameters since they are always just
+	taken from the yys parameter.  When reporting a discarded merged value
+	in debugging output, note that it is incompletely merged.  Document the
+	interface.
+	(yyresolveAction): If resolving any of the RHS states fails, destroy
+	them all rather than leaking them.  Thus, as long as user actions are
+	written to clean up the RHS correctly, yyresolveAction always cleans up
+	the RHS of a semantic option.  Document the interface.
+
+2006-02-27  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* data/glr.c (yyexpandGLRStack): Catch an off-by-one error that
+	led to a segmentation fault in GNU Pascal.  Problem reported
+	by Waldek Hebisch.
+
+2006-02-21  Joel E. Denny  <jdenny@ces.clemson.edu>
+
+	* doc/bison.texinfo (Mid-Rule Actions): Explain how to bury a
+	mid-rule action inside a nonterminal symbol in order to declare a
+	destructor for its semantic value.
+
+2006-02-16  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* data/yacc.c [(! defined yyoverflow || YYERROR_VERBOSE) && !
+	YYSTACK_USE_ALLOCA && ! defined YYSTACK_ALLOC && defined
+	__cplusplus && ! defined _STDLIB_H && !
+	((defined YYMALLOC || defined malloc) && (defined YYFREE ||
+	defined free))]: Include <stdlib.h> rather than rolling our own
+	declarations of malloc and free, to avoid problems with
+	incompatible declarations (using 'throw') C++'s stdlib.h.  This
+	should fix Debian bug 340012
+	<http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=340012>,
+	reported by Guillaume Melquiond.
+
+2006-02-13  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* NEWS: Clarify symbols versus types in unused-value warnings.
+
+	* configure.ac (AC_INIT): Bump version number.
+
+2006-02-13  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* NEWS: Version 2.1a.
+	* tests/headers.at (AT_TEST_CPP_GUARD_H): Declare yyerror and yylex,
+	since C99 requires this.
+
+2006-02-11  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* m4/c-working.m4: New file.
+	* configure.ac (BISON_TEST_FOR_WORKING_C_COMPILER): Use it.
+
+2006-02-10  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* Makefile.maint: Merge from coreutils.
+
+2006-02-09  Paul Eggert  <eggert@cs.ucla.edu>
+
+	More portability fixes for problems summarized by Nelson H. F. Beebe.
+
+	* m4/cxx.m4 (BISON_TEST_FOR_WORKING_CXX_COMPILER): Catch a
+	configuration screwup "./configure CC=/opt/SUNWspro/bin/c89
+	CFLAGS="-xarch=generic64" CXX=/opt/SUNWspro/bin/CC
+	LDFLAGS="-xarch=generic64" with Sun C 5.7 on Solaris 10; this
+	messes up because C++ code is compiled in 32-bit mode but linked
+	in 64-bit mode.
+
+2006-02-08  Paul Eggert  <eggert@cs.ucla.edu>
+
+	More portability fixes for problems summarized by Nelson H. F. Beebe.
+
+	* doc/bison.texinfo (Calc++ Scanner): Work around a bug in flex
+	2.5.31.  This resembles the 2005-10-10 patch to src/scan-skel.l.
+
+	* examples/calc++/Makefile.am (check_PROGRAMS): Renamed from
+	nodist_PROGRAMS, since we don't need to actually compile the
+	example if we're just doing a plain 'make'.  This avoids bothering
+	the installer unnecessarily about problems due to weird C++
+	compilers.
+
+2006-02-06  Paul Eggert  <eggert@cs.ucla.edu>
+
+	More portability fixes for problems summarized by Nelson H. F. Beebe.
+
+	* tests/headers.at (AT_TEST_CPP_GUARD_H): Use #include <...> rather
+	than #include "...", and compile with -I'.'.  The old method was
+	not portable, according to Posix and the C standard, and it does
+	not work with Sun C 5.7, where previous #line directives affect
+	the working directory used in later #include "..." directives.
+
+2006-02-06  Juan Manuel Guerrero  <juan.guerrero@gmx.de>
+
+	Various DJGGP specific issues in /djgpp
+
+2006-02-02  Paul Eggert  <eggert@cs.ucla.edu>
+
+	More portability fixes for problems summarized by Nelson H. F. Beebe.
+
+	* m4/cxx.m4 (BISON_TEST_FOR_WORKING_CXX_COMPILER): Check that
+	'#include <map>' works and that you can apply ++ to iterators.
+
+2006-02-01  Paul Eggert  <eggert@cs.ucla.edu>
+
+	Work around portability problems summarized by Nelson H. F. Beebe in
+	<http://lists.gnu.org/archive/html/bug-bison/2005-09/msg00021.html>.
+
+	* m4/cxx.m4 (BISON_TEST_FOR_WORKING_CXX_COMPILER): Check
+	that '#include <string>' works.
+
+	* data/lalr1.cc (yytranslate_): No longer inline, to work around a
+	porting problem to g++ 3.4.3 on Darwin 7.9.0, where g++ complained
+	"warning: sorry: semantics of inline function static data `const
+	unsigned char translate_table[262]' are wrong (you'll wind up with
+	multiple copies)".
+
+	* lib/bbitset.h (struct bitset_vtable): Rename members not, and,
+	or, xor to not_, and_, or_, and xor_, respectively.  This works
+	around a bug in GCC 3.4.3 on Irix 6.5, which apparently has a
+	random system header somewhere that includes the equivalent of
+	<iso646.h>.
+
+	* tests/headers.at (AT_TEST_CPP_GUARD_H): Don't assume that "$CC
+	-E" works; it apparently doesn't work with PathScale EKO Compiler
+	Suite Version 2.0.
+
+2006-01-30  Joel E. Denny  <jdenny@ces.clemson.edu>
+
+	During deterministic GLR operation, user actions should be able to
+	influence the parse by changing yychar.  To make this easier to fix and
+	to make glr.c easier to evolve in general, don't maintain yytoken in
+	parallel with yychar; just compute yytoken when needed.
+	* tests/glr-regression.at (Incorrect lookahead during deterministic
+	GLR): Check that setting yychar in a user action has the intended
+	effect.
+	* data/glr.c (yyGLRStack): Remove yytokenp member.
+	(yyclearin): Don't set *yytokenp.
+	(yyprocessOneStack, yyreportSyntaxError, yyrecoverSyntaxError): Examine
+	yychar rather than *yytokenp to determine the current lookahead.
+	Compute yytoken locally when needed.
+	(yyparse): Likewise.  Remove the local yytoken that yytokenp used to
+	point to.
+
+	* doc/bison.texinfo (Bison Options): Remove stray sentence fragment
+	after `--report' documentation.
+
+2006-01-30  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* src/parse-gram.y (grammar_declaration): Location of printer
+	symbol is @1, not list->location.  Bug reported by twlevo.
+	* tests/input.at (Incompatible Aliases): Adjust to above change.
+
+2006-01-29  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* tests/input.at (AT_CHECK_UNUSED_VALUES): Remove.  Instead, do
+	all the test at once.  This makes the output easier to read in the
+	normal case.
+
+	Fix a longstanding bug uncovered by bro-0.9a9/src/parse.y, which I
+	got from <http://bro-ids.org/download.html>.  The bug is that
+	when two actions appeared in succession, the second one was
+	scanned before the first one was added to the grammar rule
+	as a midrule action.  Bison then output the incorrect warning
+	"parse.y:905.17-906.36: warning: unused value: $3".
+	* src/parse-gram.y (BRACED_CODE, action): These are no longer
+	associated with a value.
+	(rhs): Don't invoke grammar_current_rule_action_append.
+	(action): Invoke it here instead.
+	* src/reader.c (grammar_midrule_action): Now extern.
+	(grammar_current_rule_action_append): Don't invoke
+	grammar_midrule_action; that is now the scanner's job.
+	* src/reader.h (last_string, last_braced_code_loc):
+	(grammar_midrule_action): New decls.
+	* src/scan-gram.l (last_string): Now extern, sigh.
+	(last_braced_code_loc): New extern variable.
+	(<INITIAL>"{"): Invoke grammar_midrule_action if the current
+	rule already has an action.
+	(<SC_BRACED_CODE>"}"): Set last_braced_code_loc before returning.
+	* tests/input.at (AT_CHECK_UNUSED_VALUES):
+	Add some tests to check that the above changes fixed the bug.
+
+2006-01-27  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* src/reader.c (symbol_should_be_used): Renamed from symbol_typed_p.
+	All used changed.  Check whether the symbol has a destructor,
+	not whether it is typed.
+	* tests/input.at (AT_CHECK_UNUSED_VALUES): Add a destructor, so
+	that the values are still reported as unused.  All line numbers
+	adjusted.
+
+2006-01-23  Paul Eggert  <eggert@cs.ucla.edu>
+
+	Work around a bug in bro 0.8, which underparenthesizes its
+	definition of YYLLOC_DEFAULT.
+	* data/glr.c: Change all uses of YYLLOC_DEFAULT to parenthesize
+	their arguments.
+	* data/lalr1.cc: Likewise.
+	* data/yacc.cc: Likewise.
+
+2006-01-22  Paul Eggert  <eggert@cs.ucla.edu>
+
+	Work around a bug in Pike 7.0, and give the Pike folks a
+	better way to override the usual int widths.
+	* data/yacc.c (b4_int_type): Use yytype_uint8, etc., so that the
+	user can override the types.
+	(short): #undef, to work around a bug in Pike 7.0.
+	(yytype_uint8, yytype_int8, yytype_uint16, yytype_int16): New types.
+	(union yyalloc.yyss): Use yytype_int16 rather than short.
+	All uses changed.
+	(yysigned_char): Remove.
+	* src/parse-gram.y (YYTYPE_UINT8, YYTYPE_INT8, YYTYPE_UINT16):
+	(YYTYPE_INT16): New macros, to test the new facility in yacc.c.
+	* tests/regression.at (Web2c Actions): Adjust to above changes.
+
+	* src/reader.c (check_and_convert_grammar): New function.
+	(reader): Close the input file even if something went wrong during
+	parsing.  Minor file descriptor leak reported by twlevo.
+
+	* src/assoc.c (assoc_to_string): Use a default: abort (); case
+	to pacify gcc -Wswitch-default.
+	* src/scan-gram.l (adjust_location): Use a default: break; case
+	to pacify gcc -Wswitch-default.
+	* src/scan-skel.h (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):
+	Move these decls to scan-skel.l, since they don't need to be
+	visible elsewhere.
+	* src/scan-skel.l: Accept the above decls.

+	local variables whose names begin with 'yy'.
+	* tests/calc.at (_AT_DATA_CALC_Y): Likewise.
+	Trivial changes from Joel E. Denny.
+
+	* 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

+	Solaris, AIX, MSC.
+	(_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.

+	user must declare alloca.
+

+	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.

+	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.

+	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>

+
+	* data/lalr1.cc (yylex_): Remove, inline its code.
+	(yyreport_syntax_error_): Remove, replaced by...

+	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

+
+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

+	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.

+	All callers changed to avoid the newline.

+
+	* 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

+	((__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.

+	(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.
+

+	* src/output.c: Include scan-skel.h.
+	(scan_skel): Remove decl, since scan-skel.h does this.
+	(output_skeleton):
+	Indent calls to "error" to pacify "make maintainer-distcheck".
+	* src/print_graph.c: Don't include <obstack.h>, as system.h does this.

+	* tests/Makefile.am ($(srcdir)/package.m4): Use $(VAR),
+	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
+	msgids; there's little point to having them translated, since they
+	can be understood only by someone who can read the
+	(English-language) source code.
+
+	Generate runtime-po/bison-runtime.pot automatically, so that we
+	don't have to worry about garbage getting in that file.  We'll
+	make sure after the next official release that old msgids don't
+	get lost.  See
+	<http://lists.gnu.org/archive/html/bison-patches/2005-07/msg00119.html>.
+
+	* runtime-po/Makefile.in.in, runtime-po/bison-runtime.pot: Remove.
+	Now auto-generated.
+	* PACKAGING: Don't claim that Gawk, GCC, Perl use this method yet.
+	Fix typos in explanations of the runtime file.
+	* bootstrap: Change gettext keyword from YYI18N to YY_.
+	Use standard Makefile.in.in in runtime-po, since we'll arrange
+	for backward-compatible bison-runtime.po files in a different way.
+	* data/glr.c (YY_): New macro, from yacc.c.
+	(yyuserAction, yyreportAmbiguity, yyreportSyntaxError, yyparse):
+	Translate messages intended for users.
+	(yyreportSyntaxError): Change "virtual memory" to "memory" to match
+	the wording in the other skeletons.  We don't know that the memory
+	is virtual.
+	* data/lalr1.cc (YY_): Renamed from _.  All uses changed.
+	Use same method that yacc.c uses.
+	Don't translate debugging messages.
+	(yy::yyreport_syntax_error): Put in a FIXME for the i18n stuff;
+	it doesn't work (yet), and requires C++ expertise to fix.
+	* data/yacc.c (YY_): Renamed from YY18N.  All uses changed.
+	Move defn to a more logical place, to be consistent with other
+	skeletons.
+	Don't translate debugging messages.
+	Don't assume line numbers fit in unsigned int; use unsigned long fmts.
+	* doc/bison.texinfo: Mention <libintl.h>.  Change glibc cross reference
+	to gettext cross reference.  Add indexing terms.  Mention YYENABLE_NLS.
+	* runtime-po/POTFILES.in: Add data/glr.c, data/lalr1.cc.
+
+	Fix yyerror / yylex test glitches noted by twlevo@xs4all.nl.
+	* tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Have yyerror return
+	void, not int.
+	* tests/glr-regression.at (Badly Collapsed GLR States):
+	Likewise.
+	(Improper handling of embedded actions and dollar(-N) in GLR parsers):
+	yylex should return 0 at EOF rather than aborting.
+
+	Improve tests for stack overflow in GLR parser.
+	Problem reported by twlevo@xs4all.nl.
+	* data/glr.c (struct yyGLRStack): Remove yyerrflag member.
+	All uses removed.
+	(yyStackOverflow): Just longjmp, but with value 2 so that caller
+	can handle the problem.
+	(YYCHK1): Use goto (a la yacc.c) rather than setting a flag.
+	(yyparse): New local variable yyresult to record the result.
+	Use result of setjmp to set it, rather than storing itinto
+	struct.
+	(yyDone): Remove label.
+	(yyacceptlab, yyabortlab, yyoverflowlab, yyreturn): New labels,
+	to mimic yacc.c.  Do not discard lookahead if it's EOF (possible
+	if YYABORT is used).
+	* tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Exit with
+	yyparse status; put status > 1 into diagnostic.
+	Check that status==2 works.
+	* tests/calc.at, tests/cxx-type.at, tests/glr-regression.at:
+	Use exit status 3 for failure to open (which shouldn't happen).
+
+2005-07-17  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* tests/conflicts.at (%nonassoc and eof):  Don't exit with status
+	1 on syntax error; just let yyparse do its thing.
+	* tests/glr-regression.at (Badly Collapsed GLR States): Likewise.
+	* tests/torture.at (AT_DATA_STACK_TORTURE): Likewise.
+	(Exploding the Stack Size with Alloca):
+	(Exploding the Stack Size with Malloc):
+	Expect exit status 2, not 1, since the parser is supposed to blow
+	its stack.  Problem reported by twlevo@xs4all.nl.
+
+	* data/glr.c (yyparse): Don't assume that the initial calls
+	to YYMALLOC succeed; in that case, yyparse incorrectly returned 0.
+	Print a stack-overflow message and fail instead.
+	Initialize the line-number information before creating the stack,
+	so that the stack-overflow message can report line zero safely.
+
+2005-07-14  Paul Eggert  <eggert@cs.ucla.edu>
+
+	Fix problems reported by twlevo@xs4all.nl.
+	* data/glr.c (YYSTACKEXPANDABLE): Don't define if already defined.
+	(yyuserMerge): Provide a default case if b4_mergers is empty.
+	* tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Define YYSTACKEXPANDABLE.
+	* tests/glr-regression.at
+	(Improper handling of embedded actions and dollar(-N) in GLR parsers):
+	Add casts to pacify C++ compilers.
+	* tests/glr-regression.at (Improper merging of GLR delayed action
+	sets): Declare yylex before using it.
+	* tests/Makefile.am (maintainer-check-g++): Fix a stray
+	$(GXX) that escaped the renaming of GXX to CXX.  Remove bogus
+	test for valgrind; valgrind is independent of g++.
+	(maintainer-check-posix): Add _POSIX2_VERSION=200112, to check
+	for compatibility with POSIX 1003.1-2001 (if running coreutils).
+	* tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Port to stricter C++.
+	Use a destructor, so that we can expand the stack.  Change
+	YYSTYPE to char * so that we can free it.  Cast result of malloc.
+
+2005-07-13  Paul Hilfinger  <hilfingr@CS.Berkeley.EDU>
+
+	* data/glr.c (yyuserAction): Fix uninitialized variable that caused
+	a valgrind failure.  Problem reported by twlevo@xs4all.nl.
+
+2005-07-13  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* PACKAGING: New file, suggested by Bruno Haible and taken from
+	similar wording in gettext's PACKAGING file.
+	* NEWS: Mention PACKAGING.
+	* Makefile.am (EXTRA_DIST): Add PACKAGING.
+
+2005-07-12  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* NEWS: Document recent i18n improvements.
+	* bootstrap: Get runtime translations into runtime-po.
+	Create runtime-po files automatically, if possible.
+	* configure.ac: Invoke BISON_I18N, so that we eat our own dog food.
+	* data/yacc.c: Rewrite inclusion of <libintl.h> so that ENABLE_NLS
+	does not infringe on the user's name space.
+	(YYENABLE_NLS): Renamed from ENABLE_BISON_NLS.
+	* doc/bison.texinfo (Internationalization): Revamp the English
+	and Texinfo syntax a bit, to try to make it clearer.
+	(Bison Options, Option Cross Key): Mention --print-localedir.
+	* m4/bison-i18n.m4 (BISON_I18N): Rename ENABLE_BISON_NLS to
+	YYENABLE_NLS.  Quote a bit more.
+	* runtime-po/.cvsignore: New file.
+	* runtime-po/Makefile.in.in (mostlyclean): Remove *.old.pot.
+	* runtime-po/Rules-quot: Remove; now created by bootstrap.

+	* runtime-po/remove-potcdate.sin: Likewise.
+	* runtime-po/Makevars: Likewise.
+	* runtime-po/LINGUAS: Likewise.
+	* runtime-po/de.po: Likewise; we will rely on the translation project
+	to maintain this, so "bootstrap" should get it.
+	* src/getarg.c (PRINT_LOCALEDIR_OPTION): Let the C compiler determine
+	its value.
+	* src/main.c (main): Bind the bison-runtime domain, too.
+
+2005-07-12  Bruno Haible  <bruno@clisp.org>
+
+	* data/yacc.c: Include <libintl.h> when NLS is enabled.
+	(YYI18N): Renamed from _. Use dgettext when NLS is enabled.
+	* po/POTFILES.in: Remove autogenerated file src/parse-gram.c.
+	* runtime-po: New directory.
+	* runtime-po/Makefile.in.in: New file, copied from po/, with modified
+	$(DOMAIN).pot-update rule, so that old messages are never dropped.
+	* runtime-po/Rules-quot: New file, copied from po/.
+	* runtime-po/quot.sed: Likewise.
+	* runtime-po/boldquot.sed: Likewise.

+	and Pennello's paper.
+
+2005-07-09  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* data/yacc.c (yyparse): Undo previous patch.  Instead,
+	set yylsp[0] and yyvsp[0] only if the initial action
+	sets yylloc and yylval, respectively.
+
+	* data/yacc.c (yyparse): In the initial action, set
+	yylsp[0] and yyvsp[0] rather than yylloc and yylval.
+	This avoids the use of undefined variables if the initial
+	action does not set yylloc and/or yylval.
+
+2005-07-07  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* examples/calc++/calc++-driver.cc, examples/calc++/calc++-driver.hh:

+	not GNU M4, and that it works with any POSIX-compatible Awk.
+	* examples/calc++/Makefile.am (run_extexi): Remove; not used.
+	($(calc_extracted)): Renamed from $(calc_sources_extracted),
+	so that we also get calc++-parser.yy.  Geneate it.
+	Use $(AWK), not gawk, since any conforming Awk will do.
+	Put comment before action, since older 'make' can't handle comment
+	in action.
+	$(BUILT_SOURCES): List all built sources, not just some of them.
+	$(MAINTAINERCLEANFILES): Remove *.stamp, and all built sources.
+	$($(srcdir)/calc++-parser.stamp): Work even if POSIXLY_CORRECT.
+	$($(calc_sources_generated)): Remove unnecessary test for existence
+	of target.  (This had a shell syntax error anyway; a stray "x".)
+	(calc_extracted): List $(srcdir)/calc++-parser.yy, not
+	calc++-parser.yy.
+	* examples/.cvsignore, examples/calc++/.cvsignore: New files.
+

+	implied by the other modules.
+
+2005-07-06  Akim Demaille  <akim@epita.fr>
+
+	Bind examples/calc++ to the package.

+	* examples/calc++/compile: Remove.
+	* examples/Makefile.am: New.

+
+2005-07-05  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* data/glr.c (yyFail): Drastically simplify; since the format argument
+	never had any % directives, we can simply pass it to yyerror.
+	(yyparse): Use "t a; a=b;" rather than "t a = b;" when a will
+	be modified later, as that is the usual style in glr.c.
+	Problems reported by Paul Hilfinger.
+
+	Rewrite GLR parser to catch more buffer overrun, storage exhaustion,
+	and size overflow errors.
+	* data/glr.c: Include <stdio.h> etc. after user prolog, not before,
+	in case the user prolog sets feature-test macros like _GNU_SOURCE.
+	(YYSIZEMAX): New macro.
+	(yystpcpy): New function, taken from yacc.c.
+	(struct yyGLRStack.yyspaceLeft): Now size_t, not int.
+	(yyinitGLRStack, yyfreeGLRstack): Remove unnecessary forward decls,
+	so that we don't have to maintain their signatures.
+	(yyFail): Check for buffer overflow, by using vsnprintf rather
+	than vsprintf.  Allocate a bigger buffer if possible.
+	Report an error if buffer allocation fails.
+	(yyStackOverflow): New function.
+	(yyinitStateSet, yyinitGLRStack): Return a boolean indicating whether
+	the initialization was successful.  It might fail if storage was
+	exhausted.
+	(yyexpandGLRStack): Add more checks for storage allocation failure.
+	Use yyStackOverflow to report failures.
+	(yymarkStackDeleted, yyglrShift, yyglrShiftDefer, yydoAction):
+	(yysplitStack, yyprocessOneStack, yyparse, yypstack):
+	Don't assume stack number fits in int.
+	(yysplitStack): Check for storage allocation failure.
+	(yysplitStack, yyprocessOneStack): Add pure_formals, so that we
+	can print diagnostics on storage allocation failure.  All callers
+	changed.
+	(yyresolveValue): Use yybool for boolean.
+	(yyreportSyntaxError): Check for size-calculation overflow.
+	This code is taken from yacc.c.
+	(yyparse): Check for storage allocation errors when allocating
+	the initial stack.
+
+2005-07-05  Akim Demaille  <akim@epita.fr>
+
+	Extract calc++ from the documentation.

+	Fix infringement on user name space reported by Bruno Haible.
+	* data/yacc.c (YYSIZE_T): Define first, so that later decls can use it.
+	Prefer GCC's __SIZE_TYPE__ if available, so that we don't infringe on
+	the user's name space.
+	(alloca): Include <stdlib.h> to get it, if it's not built in.
+	(YYMALLOC, YYFREE): Define only if needed.
+	(malloc, free): Declare, but only if needed, as this infringes on
+	the user name space.
+
+2005-05-25  Paul Eggert  <eggert@cs.ucla.edu>
+
+	Fix BeOS, FreeBSD, MacOS porting problems reported by Bruno Haible.
+	* lib/bitset.c (bitset_print): Don't assume size_t can be printed
+	with %d format.
+	* lib/ebitset.c (min, max): Undef before defining.
+	* lib/vbitset.c (min, max): Likewise.
+	* lib/subpipe.c (create_subpipe): Save local variables in case
+	vfork clobbers them.
+
+2005-05-24  Bruno Haible  <bruno@clisp.org>
+
+	* tests/synclines.at (AT_SYNCLINES_COMPILE): Add support for the

+
+2005-05-23  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* README: Mention m4 1.4.3.  Remove obsolete advice about
+	Sun Forte Developer 6 update 2, VMS, and MS-DOS.
+
+	* bootstrap: Remove workaround for problem I encountered with
+	gettext 0.14.1; it seems to be fixed now.
+
+2005-05-22  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* NEWS: Version 2.0a.
+
+	* src/files.c: Include "stdio-safer.h"; this fixes a typo in
+	the previous change.
+
+	Various maintainer cleanups.
+	* .cvsignore: Add a.exe, a.out, b.out,, conf[0-9]*, confdefs*,
+	conftest*, for benefit of CVS commands run at the same time as
+	"configure".  Add build-aux, since "bootstrap" now creates it and
+	its subfiles.
+	* Makefile.cfg (move_if_change): Remove.
+	* Makefile.maint: Remove the update stuff; we now use "bootstrap".
+	(ftp-gnu, www-gnu, move_if_change, local_updates, update):
+	(po_repo, do-po-update, po-update, wget_files, get-targets):

+	(standards.texi-url_prefix, make-stds.texi-url_prefix, taget, url):
+	($(get-targets), cvs-files, automake_repo, wget-update, cvs-update):
+	Remove.
+	* configure.ac (AC_CONFIG_AUX_DIR): Change from config to build-aux;
+	this is now the recommended name.
+	* config/.cvsignore: Remove config.guess, config.rpath, config.sub,
+	depcomp, install-sh, mdate-sh, missing, mkinstalldirs, texinfo.tex,
+	ylwrap.  These files now go into build-aux.
+	* config/move-if-change: Remove.
+	* config/prev-version.txt: Bump from 1.75 to 2.0.
+
+	* bootstrap: Add stdio-safer, unistd-safer modules.
+	Remove m4/glibc2.m4 (introduced by latest gnulib, but
+	we don't need it).
+	* lib/.cvsignore: Add dup-safer.c, fd-safer.c,
+	fopen-safer.c, stdio-safer.h, unistd-safer.h.
+	* lib/subpipe.c: Include "unistd-safer.h".
+	(create_subpipe): Make sure all the newly-created
+	file descriptors are > 2, so that diagnostics don't
+	get sent down them (which might cause Bison to hang, in theory).
+	* m4/.cvsignore: Add stdio-safer.m4, unistd-safer.m4.
+	* src/files.c (xfopen): Use fopen_safer, not fopen.
+
+	* data/lalr1.cc (yy::]b4_parser_class_name[::parse): Port
+	yesterday's yacc.c fix.
+
+2005-05-21  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* data/glr.c, data/lalr1.cc: Update copyright date.
+
+	Fix a destructor bug reported by Wolfgang Spraul in
+	<http://lists.gnu.org/archive/html/bug-bison/2005-05/msg00042.html>.
+	* data/yacc.c (yyabortlab): Don't call destructor, and
+	don't set yychar to EMPTY.
+	(yyoverflowlab): Don't call destructor.
+	(yyreturn): Call destructor, if yychar is neither YYEOF nor YYEMPTY.
+	* tests/calc.at (AT_CHECK_CALC): Expect one fewer output lines,
+	since we no longer output the message "discarding lookahead token
+	end of input ()".
+
+2005-05-20  Paul Hilfinger  <hilfingr@CS.Berkeley.EDU>
+
+	* data/glr.c (YY_SYMBOL_PRINT): Don't print newline at end to
+	fix a small glitch in debugging output.

+
+2005-05-11  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* tests/local.at (AT_COMPILE_CXX): Treat LDFLAGS like AT_COMPILE does.
+	Problem reported by Ralf Menzel.
+
+2005-05-01  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* tests/actions.at: Test that stack overflow invokes destructors.
+	From Marcus Holland-Moritz.
+	* data/yacc.c (yyerrlab): Move the code that destroys the stack
+	from here....
+	(yyreturn): to here.  That way, destructors are called properly
+	even if the stack overflows, or the user calls YYACCEPT or
+	YYABORT.  Stack-overflow problem reported by Marcus Holland-Moritz.
+	(yyoverflowlab): Destroy the lookahead.
+
+2005-04-24  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* data/yacc.c (YYSTACK_ALLOC_MAXIMUM): Add more-descriptive comment.
+
+2005-04-17  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* NEWS: Bison-generated C parsers no longer quote literal strings
+	associated with tokens.
+	* src/output.c (prepare_symbols): Don't escape strings,
+	since users don't want to see C escapes.
+	* tests/calc.at (AT_CHECK_CALC): Adjust to lack of quotes
+	in diagnostics.
+	* tests/input.at (Torturing the Scanner): Likewise.
+	* tests/regression.at (Token definitions, Web2c Actions): Likewise.
+
+2005-04-16  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* tests/torture.at (AT_INCREASE_DATA_SIZE): Skip the test if
+	the data size is known to be too small and we can't increase it.
+	This works around an HP-UX 11.00 glitch reported by Andrew Benham.
+
+2005-04-15  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* src/parse-gram.y: Include quotearg.h.
+	(string_as_id): Quote $1 before using it as a key, since the
+	lexer no longer quotes it for us.
+	(string_content): Don't strip quotes, since lexer no longer
+	quotes it for us.
+	* src/scan-gram.l: Include quotearg.h.
+	("\""): Omit quote.
+	("'"<SC_ESCAPED_CHARACTER>): Quote symbol before using it as
+	a key, since the rest of the lexer doesn't quote it.
+	* src/symtab.c (symbol_get): Don't quote symbol; caller does it now.
+	* tests/regression.at (Token definitions): Check for backslashes
+	in token strings.
+
+	* data/yacc.c (YYSTACK_ALLOC_MAXIMUM): New macro.
+	(YYSIZE_T): Define to unsigned long int when using an older compiler.
+	(yyparse): Revamp code to generate long syntax error message, to
+	make it easier to translate, and to avoid problems with arithmetic
+	overflow.  Change "virtual memory" to "memory" in diagnostic, since
+	we don't know whether the memory is virtual.
+
+2005-04-13  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* NEWS: Bison-generated C parsers now use the _ macro to
+	translate strings.
+	* data/yacc.c (_) [!defined _]: New macro.
+	All English strings wrapped inside this macro.
+	* doc/bison.texinfo (Bison Parser): Document _.
+	* po/POTFILES.in: Include src/parse-gram.c, since it now
+	includes translateable strings that parse-gram.y doesn't.
+
+2005-04-12  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* src/symtab.c (symbol_make_alias): Call symbol_type_set,
+	reverting the 2004-10-11 change to this function.
+	(symbol_check_alias_consistency): Don't call symbol_type_set
+	if the type name is already correct.
+	* tests/input.at (Typed symbol aliases): New test, from Tim Van Holder.
+
+2005-03-25  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* tests/regression.at (Token definitions): Don't use a token named
+	c, as that generates a "#define c ..." that runs afoul of buggy
+	stdlib.h that uses the identifier c as a member of struct
+	drand48_data.  Problem reported by Horst Wente.
+
+2005-03-21  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* bootstrap: Change translation URL from
+	http://www2.iro.umontreal.ca/~gnutra/po/maint/bison/ to
+	http://www.iro.umontreal.ca/translation/maint/bison/ to avoid
+	redirection glitches.  Problem reported by twlevo@xs4all.nl.
+
+2005-03-20  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* tests/local.at (AT_COMPILE, AT_COMPILE_CXX): Don't put options
+	after operands; POSIX says this isn't portable for the c99 command.
+
+2005-03-18  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* tests/glr-regression.at (glr-regr2a.y): Try to dump core
+	immediately if a data overrun has occurred; this may help us track
+	down what may be a spurious failure on MacOS.
+
+2005-03-17  Paul Eggert  <eggert@cs.ucla.edu>
+
+	Respond to problems reported by twlevo@xs4all.nl.
+
+	* bootstrap: Use "trap - 0" rather than the unportable "trap 0".
+
+	* src/vcg.h: Comment fix.
+	* src/vcg_defaults.h: Parenthesize macro bodies to make them safe.
+	(G_CMAX): Change to -1 instead of INT_MAX.
+
+	* data/yacc.c (yyparse): Omit spaces before #line.
+
+2005-03-15  Paul Eggert  <eggert@cs.ucla.edu>

+	Roland McGrath.
+
+2005-03-06  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* src/output.c (escaped_output): Renamed from
+	escaped_file_name_output, since we now use it for symbol tags as
+	well.  All uses changed.
+	(symbol_destructors_output, symbol_printers_output):
+	Escape symbol tags too.
+	Problem reported by Matyas Forstner in
+	<http://lists.gnu.org/archive/html/bug-bison/2005-03/msg00009.html>.
+
+	* src/muscle_tab.c (muscle_code_grow): Don't quote numbers; it's
+	not needed.
+	* src/output.c (user_actions_output, token_definitions_output,
+	symbol_destructors_output, symbol_printers_output): Likewise.
+	* src/reader.c (prologue_augment): Likewise.
+	* src/scan-gram.l (handle_action_dollar, handle_action_at): Likewise.
+
+	* src/vcg.c (output_edge): Don't quote linestyle arg.
+	Problem reported by twlevo@xs4all.nl.
+
+2005-02-28  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* doc/bison.texinfo (Semantic Tokens): Fix scoping problem in
+	example, reported by Derek M Jones.  Also, make the example even
+	more outrageous, to better illustrate how bad the problem is.
+
+2005-02-24  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* doc/bison.texinfo (Mfcalc Symtab): Correct the prototype for

+
+2005-02-23  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* doc/bison.texinfo (Language and Grammar): some -> same
+	(Epilogue): int he -> in the
+	Typos reported by Sebastian Piping via Justin Pence.
+
+2005-02-07  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* tests/glr-regression.at (Improper handling of embedded actions
+	and dollar(-N) in GLR parsers): Renamed from "Improper handling of
+	embedded actions and $-N in GLR parsers", work around an Autoconf bug
+	with dollar signs in test names.
+	* tests/input.at (Invalid dollar-n): Renamed from "Invalid \$n",
+	for a similar reason.
+
+2005-01-28  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* src/vcg.c (output_graph): G_VIEW -> normal_view in case someone
+	wants to redefine G_VIEW.
+
+2005-01-27  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* src/vcg.c (get_view_str): Remove case for normal_view.

+
+2005-01-24  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* configure.ac (O0CFLAGS, O0CXXFLAGS): Fix quoting bug.
+	Problem reported by twlevo@xs4all.nl.
+
+	* doc/bison.texinfo: Change @dircategory from "GNU programming

+	Problem reported by twlevo@xs4all.nl.
+
+2005-01-21  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* data/yacc.c (YYCOPY, yystpcpy, yyparse): Remove "register"
+	keyword; it's not needed with modern compilers, and it doesn't
+	affect correctness with older compilers.  Suggested by
+	twlevo@xs4all.nl.
+
+2005-01-17  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* data/glr.c (yyuserAction): Add "default: break;" case to pacify

+	* data/yacc.c (yyparse): Likewise.
+
+2005-01-12  Paul Eggert  <eggert@cs.ucla.edu>

+
+2005-01-10  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* tests/calc.at (_AT_DATA_CALC_Y): Use alarm (100), not alarm (10),

+	Nelson H. F. Beebe.
+
+2005-01-07  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* data/yacc.c (yyparse): Pacify non-GCC compilers about yyerrorlab
+	being defined and not used.
+	* data/lalr1.cc (yyparse): Likewise.
+	Use "if (false)" rather than "if (0)".
+
+2005-01-05  Paul Eggert  <eggert@cs.ucla.edu>

+
+2005-01-02  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* src/scan-skel.l (<<EOF>>): Don't close standard output.

+
+2005-01-01  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* src/getargs.c (version): Happy new year; update overall
+	program copyright date from 2004 to 2005.
+
+	* src/scan-skel.l ("@output ".*\n): Don't close standard output.
+	Problem reported by Hans Aberg.
+	* tests/output.at (AT_CHECK_OUTPUT): New arg SHELLIO.
+	(Output file names.): Add a test for the case when standard output
+	is closed.
+
+2004-12-26  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* doc/bison.texinfo (@copying): Update FDL version number to 1.2,
+	to fix an oversight in the Bison 2.0 manual.
+
+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 2.0.
+	* src/parse-gram.c, src/parse-gram.h: Regenerate with 2.0.
+
+	* tests/torture.at (Exploding the Stack Size with Alloca): Set
+	YYSTACK_USE_ALLOCA to 1 if __GNUC__ or alloca are defined;
+	otherwise, we're not testing alloca.  Unfortunately there's no
+	simple way to consult HAVE_ALLOCA here.
+
+	* 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...

+	(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.

+
+	Remove uses of 'short int' and 'unsigned short int'.  This raises
+	some arbitrary limits.  It uses more memory but nowadays that's

+
+	Ideally we should use size_t to represent all object counts, and

+	counts; but that will require more code-cleanup than I have the
