Paul Eggert 75eb3bc4e7 * If the user does not define YYSTYPE as a macro, Bison now declares it 
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  withdrawn in a future release.

Fix copyright notice.

Paul Eggert 52328c6e99 Comment fix. 2002-12-21 12:56:44 +00:00
Paul Eggert f67ad422a4 (Decl Summary): yytname's first element is not always "$end", as the 
user might specify a different name for the end token.

Paul Eggert 1c5fe69d46 Undo most of the 2002-11-12 yychar -> yytoken patch, as it broke GCC 3.2.1. 2002-12-15 09:21:13 +00:00
Paul Eggert a20713a4af Undo most of the 2002-11-12 yychar -> yytoken patch, as it broke 
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.
