Aha!  So it's the compiler-macro of add-to-list which turns an
add-to-list call into a cl-pushnew call, which is then macro-expanded to
something that uses cl-member, which should be turned into a plain
`member' by `cl--compiler-macro-member'.  So it can be fixed by changing
the compiler-macro of add-to-list not to use cl-pushnew.
