Deleting cl-loadefs.el and batch byte-compiling a file with sole contents:

(defvar foo-bar nil)
(add-to-list 'foo-bar 1)

produces byte-code containing cl-member. Makes no sense to me...

You are correct that adding

(eval-and-compile (put 'cl-member 'compiler-macro#'cl--compiler-macro-member))

to the start of the file seems to fix it.
