[LWM] SYSTEM:INTEGER-TO-64BIT undefined?

Hello,

I'm trying to build a FFI for the Mac OS X (10.3.7) CoreMIDI framework 
using LW 4.4. One of the data types defined in the MIDIServices.h file 
is:

typedef UInt64 MIDITimeStamp;

I traced down the definition of 'UInt64' and used the foreign parser to 
generate a FFI for the MacTypes.h and Math64.h headers (part of the 
CarbonCore framework). Unfortunately when I compile the results I get a 
warning that SYSTEM:INTEGER-TO-64BIT is undefined.

For example compiling:
====================================================================

(fli:define-c-typedef (uint64 (:foreign-name "UInt64"))
                       (:unsigned :long-long))

(fli:define-foreign-function (u64-subtract "U64Subtract" :source)
                              ((left uint64) (right uint64))
                              :result-type
                              uint64
                              :language
                              :ansi-c)

Results in:
====================================================================

;;; Safety = 3, Speed = 1, Space = 1, Float = 1, Interruptible = 0
;;; Compilation speed = 1, Debug = 2, Fixnum safety = 3
;;; Source level debugging is on
;;; Source file recording is  on
;;; Cross referencing is on
; (FLI:DEFINE-FOREIGN-TYPE UINT64)
; (SUBFUNCTION U64-SUBTRACT (FLI:DEFINE-FOREIGN-FUNCTION U64-SUBTRACT))
; (FLI:DEFINE-FOREIGN-FUNCTION U64-SUBTRACT)
; (FLI:DEFINE-FOREIGN-FUNCTION U64-SUBTRACT)

The following functions are undefined:
SYSTEM:UNSIGNED-BIGNUM-FROM-64BIT which is referenced by (SUBFUNCTION 
U64-SUBTRACT (FLI:DEFINE-FOREIGN-FUNCTION U64-SUBTRACT))
SYSTEM:UNSIGNED-INTEGER-TO-64BIT which is referenced by (SUBFUNCTION 
U64-SUBTRACT (FLI:DEFINE-FOREIGN-FUNCTION U64-SUBTRACT))
;;; Compilation finished with 1 warning, 0 errors.


Can I do anything without a function to coerce a fixnum or bignum to an 
'unsigned long long'?

I'm using a G4 PowerBook.

Thanks in advance for any help...
