From 75eb3bc4e7e48c5c247ede3a7ae0f0750bf0e3e8 Mon Sep 17 00:00:00 2001 From: Paul Eggert Date: Tue, 24 Dec 2002 07:40:14 +0000 Subject: [PATCH] * 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and `yyltype' are now obsolescent macros instead of being typedefs or tags; they are no longer documented and will be withdrawn in a future release.
