Unions and lexer

[Mike Rollins]

When I compile my parser, it compiles fine.  However, when it comes time to 
compile my lexer, I get the following error:

'TRANSLATION' is used as a type, but is not defined as a type.

My union looks like this:

%union YYSTYPE{
  char* id;
  TRANSLATION code;
}

I do a typedef to define TRANSLATION (it's a class):

typedef CodeString* TRANSLATION;

Even if I put the typedef in my lexer file, it's still not working.

Do I need to extern something?
