Separately, FYI, these are the warnings I get compiling the freshest SLIME:
In slime-complete-maybe-restore-window-configuration: slime.el:3620:20:Warning: `last-command-char' is an obsolete variable (as of Emacs at least 19.34); use `last-command-event' instead. slime.el:4717:20:Warning: `next-line' used from Lisp code That command is designed for interactive use only slime.el:4718:20:Warning: `previous-line' used from Lisp code That command is designed for interactive use only
This has been brought up in the past. See:
http://article.gmane.org/gmane.lisp.slime.devel/9508
and
http://article.gmane.org/gmane.lisp.slime.devel/9509
Unfortunately for the SLIME developers, this could be a recurring message as new users come to SLIME and notice the warnings.
