;; Let the stub generator know about <mqueue> type.
;; The arguments of define-type are:
;;
;; (define-type 
;;    scheme-name    ;; Scheme class name
;;    c-type         ;; C type name when unboxed
;;    description    ;; used in error message 
;;    c-predicate    ;; bool c-predicate(ScmObj obj) - check whether
;;                   ;;   obj is the type.
;;    c-unbox        ;; c-type c-unbox(ScmObj obj) - unbox obj.
;;                   ;;   You can assume obj is of the type.
;;    c-box          ;; ScmObj c-box(c-type x) - box obj.
;;    )
;;
;; Note: when you use a foreign pointer class, care should be taken
;; if you want to save the unboxed value somewhere; since the ScmObj
;; that points to the unboxed value may be unreferenced after subr
;; call, you should be responsible to make sure the unboxed pointer
;; is visible from GC.
