;;; Cross-compile script for adding some new static symbols for the
;;; core search routines.
;;;
;;; Intended only for the sparc port.  Works with Pierre Mai's build
;;; scripts.
;;;
;;; You may get an error on loading target:compiler/new-assem.  Use
;;; the CONTINUE restart (return NIL from load).  The build should
;;; continue successfully.  You should take the resulting build and
;;; recompile everything once again to be sure.
;;;
;;; I (RLT) don't know why this message is there and why it's not a
;;; real problem, but the resulting cross-compiled result should work,
;;; and does work for me.
