This is in the MCL sources :CCL 2.0:level-1:l1-boot.lisp"
which is included on the MCL CDs in the "Additional MCL Source Code" 
folder.

Please note that *inhibit-greeting* is not documented or exported so it may
disappear in future versions of MCL. In general, the default startup is not
very well documented. The important code is the default value for the
startup-function parameter to save-application. In English, the default is
to use the current toplevel function, but call startup-ccl with the
init-file first. 

(defun save-application (filename 
                         &key
                         (init-file nil)
                         (toplevel-function
                          (let ((tl (%set-toplevel)))
                            #'(lambda ()
                                (%set-toplevel tl)
                                (startup-ccl init-file))))
                         (creator :ccl2)
                         (excise-compiler nil)
                         size
                         resources
                         (clear-clos-caches t)
                         memory-options)
  ...)
