Please send me whatever changes are needed -- I don't know anything
about this, and don't have any way to test it.  I think we can use
the CCL-5.0 switch.

The code in cmn-mcl.lisp is an optimization of file output -- it
could be omitted entirely -- there are Lisp replacements at the
end of cmn-utils.lisp (these functions exist because
ACL version 3 (1989!) text file output on the NeXT
was so slow that providing C foreign function calls
sped up CMN as a whole by about a factor of 10).  I think
the *features* switch for this is :only-lisp.
