Regenerate.

* 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
is not defined.  This is an awful hack, but it's enough for now.
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.

 Bison News
 ----------
 
+Changes in version 2.1, 2005-09-16:
+
+* Bison-generated parsers now support the translation of diagnostics like
+  "syntax error" into languages other than English.  The default
+  language is still English.  For details, please see the new
+  Internationalization section of the Bison manual.  Software
+  distributors should also see the new PACKAGING file.  Thanks to
+  Bruno Haible for this new feature.
+
+* Wording in the Bison-generated parsers has been changed slightly to
+  simplify translation.  In particular, the message "memory exhausted"
+  has replaced "parser stack overflow", as the old message was not
+  always accurate for modern Bison-generated parsers.
+
+* Destructors are now called when the parser aborts, for all symbols left
+  behind on the stack.  Also, the start symbol is now destroyed after a
+  successful parse.  In both cases, the behavior was formerly inconsistent.
+
+* When generating verbose diagnostics, Bison-generated parsers no longer
+  quote the literal strings associated with tokens.  For example, for
+  a syntax error associated with '%token NUM "number"' they might
+  print 'syntax error, unexpected number' instead of 'syntax error,
+  unexpected "number"'.

+Packaging hints for binary package distributors
+===============================================
+
+Although the source of the bison package comes as a single package,
+in distributions of binary packages the installed files should
+be split into two packages:
+
+   bison-runtime
+        Contents: Runtime libraries and programs.
+        Audience: Anyone who wants to run internationalized programs
+                  that contain Bison-generated parsers.
+
+   bison
+        Contents: Tools and documentation for developers that use Bison.
+        Audience: Anyone who wants to develop programs that use parsers.
+        Dependencies: requires bison-runtime.
+
+The 'bison-runtime' binary package is much smaller than the 'bison'
+binary package.  It should be included in any distribution that
+contains localized programs that use the diagnostics contained in
+Bison-generated parsers.
+
+If you want to install both packages at the same time, you simply do
+at the toplevel directory:
+
+      ./configure
+      make
+      make install
+
+After installation, the file
+
+      $prefix/share/locale/*/LC_MESSAGES/bison-runtime.mo
+
+belongs to the bison-runtime package; all other installed files belong
+to the bison package.

-# The commit message will be extracted from the differences between a
-# file named ChangeLog* in the commit list, or named after -C, and the
-# one in the repository (unless a message was specified with `-m' or
-# `-F').  An empty message is not accepted (but a blank line is).  If
-# the message is acceptable, it will be presented for verification
-# (and possible edition) using the $PAGER environment variable (or
-# `more', if it is not set, or `cat', if the `-f' switch is given).
