-;;; FIXME: It should be possible to do this in the cross-compiler,
-;;; but currently the cross-compiler's type system is too dain-bramaged to
-;;; handle it. (Various consistency checks are disabled when this flag
-;;; is false, and the cross-compiler's type system can't pass these
-;;; checks. Some of the problems are quite severe, e.g. mismatch between
-;;; LAYOUTs generated by DEF!STRUCT and LAYOUTs generated by real
-;;; DEFSTRUCT due to DEF!STRUCT not understanding raw slots -- it's
-;;; actually somewhat remarkable that the system works..)
