 (defvar *eval-stack* (make-array 100)) ; will grow as needed
-;;; FIXME: This seems to be used by the ordinary (non-byte) interpreter
-;;; too, judging from a crash I had when I removed byte-interp.lisp from
-;;; the cold build sequence. It would probably be clearer to pull the
-;;; shared interpreter machinery out of the byte interpreter and ordinary
-;;; interpreter files and put them into their own file shared-interp.lisp
-;;; or something.
