I've replaced it as an alias. As it was obscure and partly broken I thought
that I could sneak the change through unnoticed.

To emacs-devel:

How about adding an optional argument to defvaralias so that:

(defvaralias 'tooltip-use-echo-area 'tooltip-gud-echo-area)
(make-obsolete-variable 'tooltip-use-echo-area 'tooltip-gud-echo-area "22.1")

can be written as:

(defvaralias 'tooltip-use-echo-area 'tooltip-gud-echo-area nil "22.1")
