;;; Patch file for System version 123.239
;;; Reason:
;;;  (hash-table-p (make-hash-table)) -> NIL
;;;  Make system type HASH-TABLE an alias for BASIC-HASH-TABLE.
;;;  Recompile (hash-table-p) because it uses optimized (typep).
;;;  Recompile (commonp) because it uses defsubst (hash-table-p).
;;; Written 22-Apr-88 15:59:54 by pld at site Gigamos Cambridge
;;; while running on Azathoth from band 1
;;; with Experimental System 123.238, Experimental Local-File 73.4, Experimental FILE-Server 22.2, Experimental Unix-Interface 11.0, Experimental KERMIT 34.3, Experimental ZMail 71.0, Experimental Lambda-Diag 15.0, Experimental Tape 22.1, microcode 1755, SDU Boot Tape 3.14, SDU ROM 8, the old ones.
