patch for MACL

I don't know anything about Macintosh Allegro Common Lisp, but
I have a suggestion.  Try moving the definition of print-uvector-object
in fin.lisp into the eval-when that follows, so that print-uvector-object
will be defined at compile-time too.

Thanks, this patch for fin.lisp on arisia in /pcl/tarfile-rev-3 seems toe-rev-3
seems toe-rev-3 l Lisp
