+2006-10-05 Paul Eggert <eggert@cs.ucla.edu>
+
+ Fix test failure reported by Tom Lane in
+ <http://lists.gnu.org/archive/html/bug-bison/2006-10/msg00000.html>
+ and try to make such failures easier to catch in the future.
+ * data/glr.c (YYTRANSLATE): Don't check for nonpositive arg;
+ that's now the caller's responsibility.
+ (yyprocessOneStack, yyrecoverSyntaxError, yyparse):
+ Set yychar = YYEOF if it's negative.

+
+ Fix problems with translating English-language diagnostics.

+ * po/POTFILES.in: Add src/location.c, src/scan-code.l.
+ * runtime-po/POTFILES.in: Add data/push.c.

+
+ Merge bootstrap changes from coreutils.
+
+ 2006-09-28 Jim Meyering <jim@meyering.net>
+
+ Automatically generated dependencies are important even
+ when all of the sources in a directory come from gnulib.
+ * bootstrap (gnulib_tool): Remove the "no-dependencies" automake
+ option that gnulib-tool adds to what becomes our lib/gnulib.mk.
+
+ 2006-09-23 Jim Meyering <jim@meyering.net>
+
+ * bootstrap (gnulib_tool_options): Add "--local-dir gl".
+
+ 2006-09-20 Paul Eggert <eggert@cs.ucla.edu>
+
+ * bootstrap: Add support for --force.
+ (usage): New function. Describe usage less tersely.
+ (CVS_only_file): New var.

+2006-09-21 Paul Eggert <eggert@cs.ucla.edu>
+
+ * data/push.c (YYPUSH_MORE): Make it an enum instead.

+ stamp-h1.
+
+ Sync bootstrap from coreutils, as follows:
+
+ 2006-09-18 Paul Eggert <eggert@cs.ucla.edu>
+
+ * bootstrap (symlink_to_gnulib): New function.
+ (cp_mark_as_generated): Use it, to prefer symlinks-to-gnulib
+ to copies-of-gnulib.
+ (cp_mark_as_generated, slurp, gnulib_files):
+ Avoid making a copy if it's the same as the old version.
+ (gnulib_files): Add support for this variable (used by Bison).
+
+2006-09-20 Paul Eggert <eggert@cs.ucla.edu>
+
+ * src/getargs.c (usage): Rework to use conventions similar to
+ coreutils, to make translation a bit easier and the code a bit
+ smaller. Problem reported by Tim Van Holder.
+
+2006-09-15 Paul Eggert <eggert@cs.ucla.edu>
+
+ Use some of gnulib's new modules, taken from coreutils.

+ fatal, fatal_at, warn, warn_at, unexpected_end.

+ (gl_USE_SYSTEM_EXTENSIONS): Remove; gl_EARLY now does this.
+ (gl_EARLY): Add.
+ (AM_STDBOOL_H): Remove; gl_INIT now dows this.
+ (gl_INIT): Add
+ (GNULIB_AUTOCONF_SNIPPET): Remove.
+ (AM_GNU_GETTEXT): Add; require formatstring macros since that's
+ the pickiest.
+ * lib/.cvsignore: Add inttypes_.h.
+ * lib/Makefile.am: Include gnulib.mk first so we can append to it.
+ (AM_CFLAGS): Add WERROR_CFLAGS, to be more like coreutils.

+ ulonglong.m4. Add gettext.m4, gnulib-cache.m4, gnulib-comp.m4,
+ gnulib-tool.m4, inttypes-h.m4, inttypes-pri.m4, inttypes.m4.
+ * src/Makefile.am (DEFS): Remove, since configmake does this for us.
+ (AM_CPPFLAGS): Remove -I../lib, since Automake does that for us.
+ * src/system.h: Include inttypes.h unconditionally, now that we
+ use the inttypes module. Don't bother to include stdint.h, since
+ inttypes.h now does that for us.
+ (LOCALEDIR): Remove, now that we use the configmake module.
+ * src/getargs.c: Include configmake.h.
+ * src/main.c: Likewise.
+ * src/output.c: Likewise.
+ * tests/atlocal.in (CPPFLAGS): Include from $abs_top_builddir/lib,
+ not from $abs_top_builddir, since config.h moved.
+
+
+ Port to GCC 2.95. First two problems reported by Michael Deutschmann in
+ <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00018.html>.
+
+ * src/parse-gram.y (symbol_declaration): Don't put statements
+ before declarations; it's not portable to C89.
+ * src/scan-code.l (handle_action_at): Likewise.
+
+ * src/scan-code.l: Always initialize braces_level; the old code
+ left it uninitialized and therefore had undefined behavior.
+
+ Don't attempt to redefine 'assert', since it runs afoul of
+ systems where standard headers (mistakenly) include <assert.h>.
+ Instead, define and use our own alternative, called 'aver'.
+ * src/reader.c: Don't include assert.h, since we no longer
+ use assert.
+ * src/scan-code.l: Likewise.
+ * src/system.h (assert): Remove, replacing with....
+ (aver): New function, taking a bool arg. All uses changed.
+ * src/tables.c (pack_vector): Ensure that aver arg is bool,
+ not merely an integer.

+ * src/scan-gram.l: Scan new PERCENT_PUSH_PARSER token.
+ * tests/calc.at (_AT_CHECK_CALC_ERROR): Add "Return" and "Now" to
+ list of removed lines from the traces observed.
+ (AT_CHECK_CALC_LALR): Added push parser tests.
+
+2006-09-13 Paul Eggert <eggert@cs.ucla.edu>
+
+ * NEWS: Version 2.3a.
+ * configure.ac (AC_INIT): Likewise.
+
+ * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Remove
+ "#define YYSTYPE int" that caused "make maintainer-check" to fail
+ due to header ordering dependencies. I don't know why the #define
+ was there.
+
+ Fix glr.cc and lalr1.cc's use of YYDEBUG so that there's zero
+ runtime cost when YYDEBUG is not defined, and so that some tests
+ that used to fail now work. Problem and initial suggestion by
+ Paolo Bonzini.
+ * data/c++.m4 (b4_parse_param_cons): Omit leading ','.
+ * data/glr.cc (b4_parser_class_name):
+ Initialize yycdebug_ only if YYDEBUG. Also, initialize yydebug_.
+ (debug_level, set_debug_level): Affect yydebug_, not ::yydebug.
+ (yydebug_) [YYDEBUG]: New member.
+ (yycdebug_): Now defined only if YYDEBUG.
+ * data/lalr1.cc (yydebug_, yycdebug_): Now defined only if YYDEBUG.
+ (YYCDEBUG) [!YYDEBUG]: Don't use yydebug_ and yycdebug_.
+ (b4_parser_class_name): Initialize yydebug_ and yycdebug_ only
+ if YYYDEBUG.
+ (debug_stream, set_debug_stream, debug_level, set_debug_level):
+ Define only if YYDEBUG.
+ * tests/calc.at (_AT_DATA_CALC_Y) [!YYDEBUG]: Omit call to
+ set_debug_level.
+ * tests/regression.at (_AT_DATA_DANCER_Y) [!YYDEBUG]: Likewise.
+ * tests/calc.at (AT_CHECK_CALC_GLR_CC): Uncomment calls to
+ AT_CHECK_CALC_GLR_CC that are working now.
+
+2006-09-12 Paul Eggert <eggert@cs.ucla.edu>
+
+ * data/glr.cc (YYERROR_VERBOSE, YYTOKEN_TABLE): Remove.
+ We don't need them in glr.cc, and glr.c defines them.
+ Defining YYERROR_VERBOSE to 0 here breaks glr.c, since glr.c
+ assumes that defining it to anything is the same as defining
+ it to 1. Problem reported by Paolo Bonzini.
+
+2006-09-12 Paolo Bonzini <bonzini@gnu.org> (tiny change)
+
+ * data/c.m4 (b4_null, b4_case): Define.
+ * src/output.c (prepare_symbols): Use b4_null.
+ (user_actions_output): Use b4_case.
+
+2006-09-11 Paul Eggert <eggert@cs.ucla.edu>
+
+ * data/glr.c (b4_shared_declarations): Put start-header first,
+ before any #includes that we generate, so that feature-test
+ macros work. Problem reported by Michael Deutschmann in
+ <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00004.html>.
+ * data/lalr1.cc: Likewise.
+ * doc/bison.texinfo (Prologue): Document that feature-test macros
+ should be defined before any Bison declarations.
+ * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Put defns
+ that depend on location.hh after, not before, Bison decls, since
+ we now include location.hh after the first user prologue.
+
+ * doc/bison.texinfo (Calc++ Parser): Fix memory leak reported by
+ Sander Brandenburg in
+ <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00002.html>.
+ Also, fix minor white space and comment issues.
+ (Prologue): Mention that it's better to define feature-test macros
+ before Bison declarations. Problem reported by Michael Deutschmann.
+
+ * README-cvs: Fix typo: "&" should be "&&". Problem reported
+ by Jim Meyering.
+ * m4/.cvsignore: Add argmatch.m4. Remove obstack.m4, strerror_r.m4.
+ This adjusts to recent gnulib changes.
+
+2006-09-04 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ Finish implementation of per-type %destructor/%printer. Discussed
+ starting at
+ <http://lists.gnu.org/archive/html/bison-patches/2006-02/msg00064.html>
+ and
+ <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00091.html>.

+ %destructor/%printer description.
+ * doc/bison.texinfo (Freeing Discarded Symbols): Likewise.
+ * src/symlist.c (symbol_list_destructor_set, symbol_list_printer_set):
+ Invoke semantic_type_destructor_set or semantic_type_printer_set when a
+ list node contains a semantic type.
+ * src/symtab.c, src/symtab.h: Extend with a table that associates
+ semantic types with their %destructor's and %printer's.
+ (semantic_type_from_uniqstr, semantic_type_get,
+ semantic_type_destructor_set, semantic_type_printer_set): New functions
+ composing the public interface of that table.
+ (symbol_destructor_get, symbol_destructor_location_get,
+ symbol_printer_get, symbol_printer_location_get): If there's no
+ per-symbol %destructor/%printer, look up the per-type before trying
+ the default.
+ * tests/actions.at (Per-type %printer and %destructor): New test case.
+ * tests/input.at (Default %printer and %destructor redeclared):
+ Extend to check that multiple occurrences of %symbol-default in a
+ single %destructor/%printer declaration is an error.
+ (Per-type %printer and %destructor redeclared, Unused values with
+ per-type %destructor): New test cases.
