Hello!

Cc:ing the SLIME-devel mailing list because it's an upstream bug.

This is reproducible on my sid-amd64 with a simple (require 'swank) in
SLIME and SBCL_1:1.0.12.0-1 on emacs-snapshot_1:20080101-1 (GNU Emacs
23.0.50.1).  For this reason it's not an arnesi bug, but a SLIME one,
reassigning.

The bug doesn't happen with SLIME_1:20070628-1, but only starting with
version 1:20070927-3, which unconditionally loads all the fancy stuff:
the WARNING happears with contrib/swank-presentation-streams.lisp.

Thx, bye,
