Yup.  My local Emacs is currently pretty broken because I started to
compile all files as "lexical-binding = t".

That's the question that the byte-compiler can't answer: maybe they
really weren't used (so you can remove them), or maybe they were used
elsewhere via dynamic scoping (in which case you need to add a (defvar
<var>) to force the use of dynamic scoping for this variable).

It's very common to have variables that aren't used (since the
byte-compiler didn't warn about it).
