It turns out to start with [svn r12306], and it never went away.  I 
thought that you had corrected this with [svn r12324] based on your 
comment, but had not actually verified it in my installation.

Reproducing this problem is simple.

1.  Create a file to compile named "foo.lisp" containing the form

	(defun foo () 42)

     The contents of the file don't seem to matter.

2.  Start ABCL, compile the file
	CL-USER> (compile-file "foo")

3.  Quit ABCL.

4.  Restart ABCL, issuing

	CL-USER> (load "foo")

You'll see an warning along the lines of

#P"/Users/evenson/work/abcl/foo.lisp" (previously defined in NIL)


"A screaming comes across the sky.  It has happened before, but there
is nothing to compare to it now."
