+
+2005-09-26 Paul Eggert <eggert@cs.ucla.edu>
+
+ * bootstrap (gnulib_modules): Add verify.

+
+2005-09-20 Paul Eggert <eggert@cs.ucla.edu>
+

+ doesn't affect behavior.
+ (YYSTACK_ALLOC) [YYSTACK_USE_ALLOCA]: Improve support for
+ Solaris, AIX, MSC.
+ (_STDLIB_H): Renamed from YYINCLUDED_STDLIB_H. All uses changed.
+ This works a bit better with glibc, if user code has already included

+ * 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,

+ * 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.

+
+ * 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

+ (yyFail, yyMemoryExhausted, yyreportAmbiguity):
+ Add __attribute__ ((__noreturn__)).
+

+ that we're the same as coreutils.
+ (alpha, beta, major): Depend on news-date-check.
+ Make the upload commands.

+ * 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

+
+2005-07-22 Paul Eggert <eggert@cs.ucla.edu>
+
+ * configure.ac: Update version number.
+

+
+ * NEWS: Mention recent yytname changes.
+ * THANKS: Add Anthony Heading, twlevo@xs4all.nl.
+
+ * bootstrap: For translations that have not yet been upgraded to
