+2005-09-16 Paul Eggert <eggert@cs.ucla.edu>
+
+ * NEWS: Version 2.1.
+
+ * NEWS: Remove notice of yytname change, since it was never in an
+ official release.
+ * data/glr.c (yydestroyGLRState): Rename local var to avoid shadowing
+ diagnostic.
+ * src/output.c (prepare): Likewise.
+ * data/lalr1.cc (YYERROR_VERBOSE_IF): New macro.
+ (yysyntax_error_): Use it to avoid GCC warning when YYERROR_VERBOSE

+ 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.

+ * data/lalr1.cc: Use b4_token_enums instead of b4_token_enums_defines.
+ * data/c.m4 (b4_yydestruct_generate, b4_yysymprint_generate): Define
+ as default values.
+
+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):

+
+2005-09-16 Akim Demaille <akim@epita.fr>
+
+ * doc/bison.texinfo (Calc++ Parser): Don't promote defining YYEOF

+
+2005-09-15 Paul Eggert <eggert@cs.ucla.edu>
+

+ changed.
+ (class position): file_name -> filename (reverting). All uses changed.
+
+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.
+ All uses of jmp_buf, setjmp, longjmp changed to use these instead.
+ (yyparse): Abort if user code uses longjmp to throw an unexpected
+ value.
+
+2005-09-09 Paul Eggert <eggert@cs.ucla.edu>
+
+ * data/c.m4 (b4_identification): Define YYBISON_VERSION.
+ 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
+ the context.
+ (Invocation): The output of "bison hack/foo.y" goes to foo.tab.c,
+ not to hack/foo.tab.c.
+ (Calc++ Top Level): 2nd arg of main is not const.
+ * data/glr.c: b4_filename -> b4_file_name.
+ * data/lalr1.cc: Likewise. Also, b4_filename_type -> b4_file_name_type.

+ Problem reported by Joel E. Denny in:
+ http://lists.gnu.org/archive/html/bison-patches/2005-08/msg00029.html
+
+2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
+
+ * README-cvs: Give URLs for recommended tools.
+ Mention Gzip version problem, and bootstrapping issues.
+ Remove troubleshooting section, as it's somewhat obsolete.
+

+ variants. Use it instead of '-C off'. Problem reported by
+ twlevo@xs4all.nl.
+
+ * data/glr.c (yydestroyStackItem): New function.
+ (yyrecoverSyntaxError, yyreturn): Use it to improve quality of
+ debugging information. Problem reported by Joel E. Denny.
+
+2005-08-25 Akim Demaille <akim@epita.fr>
+
+ * tests/local.at (AT_COMPILE_CXX): Pass $LINKS too.
+
+2005-08-24 Paul Eggert <eggert@cs.ucla.edu>
+
+ * data/glr.c (yyrecoverSyntaxError, yyreturn):
+ Don't invoke destructor on unresolved entries.
+ * tests/glr-regression.at

+
+2005-08-21 Paul Eggert <eggert@cs.ucla.edu>
+
+ * lib/.cvsignore: Remove realloc.c, strncasecmp.c, xstrdup.c.
+ Add strnlen.c.
+ * m4/.cvsignore: Remove codeset.m4, gettext.m4, lib-ld.m4,
+ 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.
+ * tests/calc.at (_AT_CHECK_CALC_ERROR): Adjust to the above change.
+
+ * src/files.c: Remove obsolete FIXME comment.
+
+ * data/glr.c (YY_SYMBOL_PRINT): Append a newline, for consistency
+ with the other templates, and to fix bogus run-on messages such
+ as the one reported at the end of
+ <http://lists.gnu.org/archive/html/help-bison/2005-07/msg00040.html>.
+ All callers changed to avoid the newline.
+ (yyprocessOneStack): Output two lines rather than one, to accommodate
+ the above change. This changes the debug output format slightly.
+
+ * data/glr.c (yyresolveValue): Fix redundant parse tree problem
+ reported by Joel E. Denny in
+ <http://lists.gnu.org/archive/html/bison-patches/2005-08/msg00004.html>
+ (trivial change).
+ * tests/glr-regression.at (Duplicate representation of merged trees):
+ 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.

+
+ * 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.
+ * src/reader.h (gram_end, gram_lineno): New decls to pacify
+ "make maintainer-distcheck".
+ * src/scan-skel.l (skel_lex, skel_get_lineno, skel_get_in):

+ (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.
+
+ * 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.

+
+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

+ 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):

+ (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):
