+
+	* 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).

 	* tests/conflicts.at (%nonassoc and eof):  Don't exit with status
