+
+ * data/c.m4, data/lalr1.cc, data/yacc.c: Normalize white space.

+
+ * 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/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".

+
+ * 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
+ 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/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/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

+ * runtime-po/boldquot.sed: Likewise.
+ * runtime-po/en@quot.header: Likewise.

+
+2005-07-12 Akim Demaille <akim@epita.fr>
+
+ * src/symtab.h, src/symtab.c (symbol_print): Swap the arguments,
+ for consistency with the rest of the code.
+ * src/symlist.h, src/symlist.c (symbol_list_print): Ditto.
+ Add separators.
+
+2005-07-12 Akim Demaille <akim@epita.fr>
+
+ * src/parse-gram.y: Use %printer instead of YYPRINT.
+
+2005-07-12 Akim Demaille <akim@epita.fr>
+
+ * src/symtab.h, src/symtab.c (symbol_print): New.
+ * src/symlist.h, src/symlist.c (symbol_list_print): New.
+ * src/symlist.c (symbol_list_n_type_name_get): Report the culprit.
+
+2005-07-12 Akim Demaille <akim@epita.fr>
+
+ * data/glr.c (b4_syncline): Fix (swap) the definitions of
+ b4_at_dollar and b4_dollar_dollar.
+
+2005-07-11 Paul Eggert <eggert@cs.ucla.edu>
+
+ * doc/bison.texinfo (Mystery Conflicts): Add reference to DeRemer
+ 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:
+ * 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.
+
+ * bootstrap (gnulib_modules): Add gettext, now that it's no longer
+ implied by the other modules.
+
+2005-07-06 Akim Demaille <akim@epita.fr>
+
+ Bind examples/calc++ to the package.

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

+ * doc/Makefile.am (clean-local): New, for more recent texi2dvis.
+
+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,

+ 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.

+
+ * 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

+ 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>

+ "#if 0", since it's not currently used. Problem reported by
+ 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/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
+ putsym. Typo reported by Sebastian Piping.
+
+2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
