To placate Flycheck regarding the use of cl-assert, I required
'cl-macs when compiling.  So I had:

< Some defconst invocations >
< One defvar >
< Some other declare-function invocations >
(declare-function cl-set-difference "cl-seq" (list1 list2 &rest cl-keys))
< Some other declare-function invocations >
(eval-when-compile
  (require 'cl-macs))

And I just found out (after trial and error) that the declare-function
of cl-set-difference only placates Flycheck when it comes *after* that
eval-when-compile form.  So I moved the eval-when-compile to the top and
now I have:

(eval-when-compile
  (require 'cl-macs))
< Some defconst invocations >
< One defvar >
< Some other declare-function invocations >
(declare-function cl-set-difference "cl-seq" (list1 list2 &rest cl-keys))

That solved the problem.  I have no idea why, though.
