I would use #+MCL instead of #+Coral.  Also, there are two undocumented variables
*.fasl-pathname* and *.lisp-pathname* which contain pathnames with just the
type fields filled in.  You can call pathname-type on these to get the string equivalents
(the defaults are "fasl" and "lisp").  So my suggestion on how to change these three
functions:

(defun file-type-for-sources ()
  #+MCL #.(pathname-type *.lisp-pathname*)
  #+genera "LISP"
  #+unix "lisp"
  #+(and (not genera) (not unix)) (error "Not yet implemented."))

(defun file-type-for-binaries ()
  #+MCL #.(pathname-type *.fasl-pathname*)
  #+genera                   si:*default-binary-file-type*
  #+allegro                  #.(pathname-type (compile-file-pathname "foo"))
  #+lucid                    (car lcl:*load-binary-pathname-types*)
  #+(and (not genera)
         (not allegro)
         (not lucid))
  (error "Not yet implemented."))

(defun suggest-bin-directory (&optional (base *load-pathname*)
                                        (prefix "BIN-"))
  ;; The number of different binaries you must have is
  ;; the cross product of the instruction set and the gui.
  (let ((instruction-set
         #+MCL              "MCL"
         #+GENERA           "GENERA"
         #+LUCID            "LUCID"

                                 gui))))
