        * cp-tree (struct cp_decl_specifier_seq): Rename to
        conflicting_specifiers_p

        conflicting_specifiers_p for the input decl specifier

        multiple_specifiers_p to conflicting_specifiers_p.
        (cp_parser_decl_specifier_seq) <RID_TYPEDEF>: If a storage

        set conflicting_specifiers_p to true on the decl_specs.
        * decl.c (grokdeclarator): Rename uses of
        multiple_specifiers_p to conflicting_specifiers_p.
