+ <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.

+ 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>

+
+ 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.
+
+ * bootstrap: Sync from coreutils, except add support for gnulib_files.
+ * bootstrap.conf: New file.
+ (gnulib_modules): Add configmake, inttypes, unistd.
+ (XGETTEXT_OPTIONS): Add complain, complain_at,
+ fatal, fatal_at, warn, warn_at, unexpected_end.
+ * configure.ac (AC_CONFIG_HEADERS): config.h is now in lib, not here.
+ (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.
+ (BUILT_SOURCES, EXTRA_DIST, MOSTLYCLEANFILES): Remove
+ no-longer-necessary initializations.
+ (lib_SOURCES): Remove, replacing by libbison_a_SOURCES.
+ * lib/subpipe.c: Include <unistd.h> unconditionally, now that we
+ use the unistd module.
+ * src/system.h: Likewise.
+ * m4/.cvsignore: Remove *_gl.m4, gnulib.m4, inttypes_h.m4, uintmax_t.m4,
+ 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>

+ * 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
