+       * NEWS: Instead of %union, you can define and use your own union type
+       YYSTYPE if your grammar contains at least one <type> tag.
+       Your YYSTYPE need not be a macro; it can be a typedef.
+       * doc/bison.texinfo (Value Type, Multiple Types, Location Type):
+       (Union Decl, Decl Summary): Document this.
+       * data/glr.c (YYSTYPE): Implement this.
+       * data/glr.cc (YYSTYPE): Likewise.
+       * data/lalr1.cc (YYSTYPE): Likewise.
+       * data/yacc.c (YYSTYPE): Likewise.
+       * src/output.c (prepare): Output tag_seen_flag.
+       * src/parse-gram.y (declaration, grammar_declaration):
+       Use 'union_seen' rather than 'typed' to determine whether
+       %union has been seen, since grammars can now be typed without
+       %union.
+       (symbol_declaration, type.opt, symbol_def):
+       Keep track of whether a tag has been seen.
+       * src/reader.c (union_seen, tag_seen): New vars.
+       (typed): remove.
+       * src/reader.h (union_seen, tag_seen, typed): Likewise.
+       * src/scan-code.l (untyped_var_seen): New variable.
+       (handle_action_dollar): Adjust to above changes.
+       (handle_action_dollar, handle_action_at):
+       Improve overflow checking for outlandish numbers.
+       * tests/input.at (AT_CHECK_UNUSED_VALUES): Redo test to
+       avoid new diagnostics generated by above changes.
+       * tests/regression.at (YYSTYPE typedef): Add test to check
+       for type tags without %union.
+
+       * src/symlist.c (symbol_list_length): Return int, not unsigned
+       int, since callers expect int.  This may need to get revisited
+       once we have proper integer overflow checking.
+
+       * src/scan-gram.h (gram_scanner_cursor): Remove decl, since this
+       object is now static.
+
+       * src/getargs.c (flags_argmatch): Return void, not int,
+       to pacify ./configure --enable-gcc-warnings.
+
+       * src/flex-scanner.h (STRING_FREE): Don't use FLEX_PREFIX (last_string)
+       since last_string is already defined to FLEX_PREFIX (last_string).

+
+       Implement --warnings/-W.
+       * src/getargs.c (report_argmatch, trace_argmatch): Remove,
+       replaced by...
+       (flags_argmatch, FLAGS_ARGMATCH): this new function and macro.
+       Adjust callers.
+       * src/getargs.h, src/getargs.c (warnings, warnings_flags)
+       (warnings_args, warnings_types): New.
+       (getargs, short_options, long_options): Accept -W/--warnings.
+       Sort the options by alphabetical order, upper case letter right
+       before its lower case.
