If you really want it to signal an error, you could add a clause such
as (t (:or)). E.g.:
(define-foreign-library sdl-glue
(:windows "lispbuilder-sdl-glue.dll")
(t (:or)))
In this case, I suppose you could also do something like:
(defparameter *glue-loaded-p* #+windows t #-windows nil)
Or, perhaps even better:
(defparameter *glue-loaded-p* (foreign-library-loaded-p 'sdl-glue))
