        * pt.c (process_template_parm): Store invalid template
        parameters as a TREE_LIST with a TREE_VALUE of error_mark_node.
        (push_inline_template_parms_recursive): Check for template
        parameters having a TREE_VALUE of error_mark_node rather than
        check the parameter itself.
        (mangle_class_name_for_template): Likewise.
        (comp_template_parms): When comparing the individual template
        parameters, return 1 if either is error_mark_node.
        (current_template_args): Robustify.
        (redeclare_class_template): Likewise.
