On my emacs 25.3.1, filladapt.el complains of the backquotes problem,
but compiles (after I fix another small problem, elsewhere) and seems to
run.

Don't know enough elisp to fully replace the `, construct here
  (defmacro defcustom (var value doc &rest args) 
     (` (defvar (, var) (, value) (, doc))))))
with non-deprecated code.
