AKCL problem with compile-file

[Reggie Perry <reggie@muon.phys.washington.edu>]

	Hi there. I am running AKCL version 1.619 on a SGI Indigo
under IRIX 4.0.5. I am having a big problem with compile-file. here is
the most interesting problem. Consider the file foo.lsp:

(defun foo (&optional (a nil b) &rest c)
  (list a b c))

Now here is the AKCL session:

AKCL (Austin Kyoto Common Lisp)  Version(1.619) Mon Jul 26 02:00:03

>(compile-file "foo")
Compiling foo.lsp.

End of Pass 2.

>(load "foo")

	I have no idea how to go about solving this. Any help would be
greatly appreciated. Thanks
