Re: %union errors that shouldn't be there

[Hans Aberg]

It looks as though the C++ compiler does not see the declaration of 
the types astNode, string (is it std::string?), nodeList, before it 
sees the union that the parser implements. So, you have to make sure 
that info is included somewhere, perhaps in the %{ ... %} segment 
before the %union in the .y file.
