[antlr-interest] Antlr v2 conflict

[Daniela da Cruz]

Hi

I have a conflict because:

declaration: declaration_specifiers declarator;

declaration_specifiers: (type_qualifier | type_specifier)+

declarator: IDENT

type_specifier: "int" | ... | IDENT


both the type_specifier and declarator can be IDENT.

So, if I have "int a" it matches twice on type_specifier and it should be
one type_specifier and then declarator.

thanks
daniela
