Gah?  How can this be?  I mean, C-h l tells that the key in question
is the DEL key.  Hm.

Is the statement really executed?  Try putting (message "Hi there")
(sit-for 3) before and after the statement to see if Emacs ever gets
there.  Also try M-: to eval the statement from a running Emacs, to
see if that has any effect.

Hm.  Oh!  It could be that the key is not bound in the global map,
but instead in some local map, instead.  Try C-x b foo RET, which
creates a buffer named foo in fundamental mode.  Maybe the DEL key
works in that mode?

I think that emacs-lisp-mode or lisp-interaction-mode have their own
bindings for DEL, so you'd have to do like

(define-key emacs-lisp-mode-map (kbd "DEL") 'delete-char)

for those.
