;;;; This is the cross-compile script for adding the (complex
;;;; double-double-float), (simple-array double-double-float (*)), and
;;;; (simple-array (complex double-double-float) (*)) types for sparc.
;;;;
;;;; Use the standard src/tools/cross-build-world.sh script with this
;;;; cross-compile script to generate a double-double-float build.
;;;; Something like
;;;;
;;;;   src/tools/cross-build-world.sh xtarget xcross <this-file> <dd-reader>
;;;;
;;;; I think this has to be built using a version that has reader
;;;; support for double-double-float.  I didn't try it any othe way.
;;;;
;;;; Once that has been done, you still need to do a full set of
;;;; builds to get these new types completely integrated in.  Don't
;;;; need any special bootstrap files for this, so
;;;;
;;;;   src/tools/build.sh -C "sun4_solaris_sunc" -o "xtarget/lisp/lisp -noinit"
