unused local variables

[山本和彦]

Hello,

Please tell me how to detect unused local variables of Elisp.

The XEmacs byte compiler tells unused local variables. But I cannot
find the same method in Emacs.

I don't use XEmacs but keep it in my computer only to detect used
local variables of my developing Elisp code. If I can detect them with
Emacs, I want to remove XEmacs from my computer...
