Remove obsolete references to bison.simple and bison.hairy.
* src/getargs.c (getargs) [MSDOS]: Don't assume optarg != NULL.
* src/parse-gram.y (declaration): Use enum "report_states".
* src/scan-skel.l ("@output ".*\n): Close any old yyout before new one.
using typedef instead of defining it as a macro. POSIX requires this.
For consistency, YYLTYPE is also declared instead of defined.
%union directives can now have a tag before the `{', e.g., the
directive `%union foo {...}' now generates the C code
`typedef union foo { ... } YYSTYPE;'; this is for Yacc compatibility.
The default union tag is `YYSTYPE', for compatibility with Solaris 9
Yacc. For consistency, YYLTYPE's struct tag is now `YYLTYPE'
instead of `yyltype'.
`yystype' and `yyltype' are now obsolescent macros instead of being
typedefs or tags; they are no longer documented and will be
withdrawn in a future release.
token_type, not braced_code code_kind. All uses changed.
(SC_PRE_CODE): New state, for scanning after a keyword that
has (or usually has) an immediately-following braced code.
(token_type): New local var, to keep track of which token type
to return when scanning braced code.
(<INITIAL>"%destructor", <INITIAL>"%lex-param",
<INITIAL>"%parse-param", <INITIAL>"%printer,
<INITIAL>"%union"): Set token type and BEGIN SC_PRE_CODE
instead of returning a token type immediately.
(<INITIAL>"{"): Set token type.
(<SC_BRACED_CODE>"}"): Use it.
(handle_action_dollar, handle_action_at): Now returns bool
indicating success. Fail if ! current_rule; this prevents a core dump.
(handle_symbol_code_dollar, handle_symbol_code_at):
Remove; merge body into caller.
(handle_dollar, handle_at): Complain in invalid contexts.
const *, since it is now modified by stripping surrounding { }.
(current_braced_code): Remove.
(PERCENT_DESTRUCTOR, PERCENT_PRINTER, PERCENT_UNION,
PERCENT_LEX_PARAM, PERCENT_PARSE_PARAM): Change names to include
trailing " {...}". Now of type <chars>.
(grammar_declaration): Adjust to bundled tokens.
(code_content): Remove; stripping is now done by add_param.
(print_token_value): Print contents of bundled tokens.
(token_name): New function.

(YYSTYPE): Renamed from yystype.
(YYSTYPE_IS_DECLARED): New macro, used to prevent double-typedef.
(struct YYLTYPE): Renamed from struct yyltype.
(YYLTYPE): Renamed from yyltype.
(yyltype, yystype): New (and obsolescent) macros,
for backward compatibility.
(YYSTYPE): Declare as union YYSTYPE if the user
does not specify a union tag. This is for compatibility with
Solaris 9 yacc.

Fix copyright notice.
GCC 3.2.1 (which depends on yychar == YYEMPTY when there is no
lookahead symbol, and which sets yychar in parser actions) and it
disagreed with the Bison documentation. This should fix the bug
reported by Andrew Walrond in
<http://mail.gnu.org/pipermail/bug-bison/2002-December/001949.html>.
(YYTRANSLATE): Don't check for negative argument,
as the caller now does that.
(yyclearin, YYBACKUP, yyparse): Use yychar, not yytoken.
(YYEMPTY): Parenthesize right hand side, since others use it.
(yyparse): Don't assume that our generated code is the only code
that sets yychar.
