13.9.7 define-foreign-function result-type :void

The function defined by fli:define-foreign-function (or fli:define-foreign-funcallable ) now returns no value when result-type is :void . In previous releases, the value nil was returned. In practice, this change only affects cases where additional values are returned due to arguments with :reference or :reference-return types.
