PCL compilation problem under Allegro CL 1.3.1

[Ei-ichi Osawa <osawa@csl.sony.co.jp>]

I'm installing PCL (12/7/88) on a Macintosh II under Allegro Common
Lisp 1.3.1, but I've got the following warning message and compilation
error.  Does anyone have any idea to fix this problem?  Thanks in
advance.
