;;;; ABCL-specific extensions to ASDF, placed in a separate file from
;;;; asdf.lisp so that we can track upstream ASDF versions easier.

;;; We don't compile if the output location would be within a JAR
;;; file, which is currently always an unwritable location in ABCL.
;;; This allows us to load ASDF definitions that are packaged in JARs.
;;;
;;; XXX How does this work with ASDF-BINARY-LOCATIONS?
