* doc/bison.texinfo (Parser Function): Document when yyparse
returns 2.
* data/lalr1.cc: Revert part of previous change, as it's incompatible.
(b4_filename_type): Renamed back from b4_file_name_type. All uses
changed.
(class position): file_name -> filename (reverting). All uses changed.
All uses changed. Invoke user destructor after an error during a
split parse (trivial change from Joel E. Denny).
* tests/glr-regression.at
(User destructor after an error during a split parse): New test case.
Problem reported by Joel E. Denny in:
http://lists.gnu.org/archive/html/bison-patches/2005-08/msg00029.html
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/lalr1cc (yyerturn): Likewise.
* data/yacc.c (yyreturn): Likewise.
* tests/calc.at (_AT_CHECK_CALC_ERROR): Adjust to the above change.
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 (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_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.

* 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.
(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.

(skel_set_in, skel_set_out, skel_get_debug, skel_set_debug):
(skel_lex_destroy, scan_skel): Move these decls to...
* src/scan-skel.h: New file.
* src/uniqstr.c (uniqstr_assert):
Indent calls to "error" to pacify "make maintainer-distcheck".
* 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.
* 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.
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.
* 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.
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).
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.
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.
(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):
YYSTYPE is char *, not char const *, so that strcpy ($$, ...) works.
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.
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.s (PRINT_LOCALEDIR_OPTION): Let the C compiler determine
its value.
* src/main.c (main): Bind the bison-runtime domain, too.
* 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/quot.sed: Likewise.
* runtime-po/boldquot.sed: Likewise.
* runtime-po/en@quot.header: Likewise.
* runtime-po/en@boldquot.header: Likewise.
* runtime-po/insert-header.sin: Likewise.
* runtime-po/remove-potcdate.sin: Likewise.

* runtime-po/LINGUAS: New file.
* runtime-po/bison-runtime.pot: New file.
* runtime-po/de.po: New file.
* m4/bison.m4: New file.
* Makefile.am (SUBDIRS): Add runtime-po.
(aclocaldir, aclocal_DATA): New variables.
* configure.ac: Add AC_CONFIG_FILES of runtime-po/Makefile.in.
Define aclocaldir.
* src/getargs.c (usage): Document --print-localedir option.
(PRINT_LOCALEDIR_OPTION): New enum item.
(long_options): Add --print-localedir option.
(getargs): Handle --print-localedir option.
* doc/bison.texinfo (Bison Parser): Remove paragraph about _().
(Internationalization): New section.
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.
* examples/calc++/calc++-scanner.ll, examples/calc++/calc++.cc:
Remove from CVS. These files are automatically generated.
* examples/extexi: Clarify that this file is now part of Bison,
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.
