* eval.c (evaluate_subexp, case UNOP_LOGNOT): If following opcode
is OP_SCOPE, give an error. * eval.c (evaluate_subexp): Pass third arg to lookup_struct_elt_type. * eval.c (evaluate_subexp), values.c (value_virtual_fn_field): Don't bother to do anything with return value from fill_in_vptr_fieldno. * eval.c (evaluate_subexp): If value_static_field returns NULL, give an error.
