Hi,

This change introduces new compiler warnings from (featurep 'xemacs)
forms that were previously silent. Minimal example is compiling a file
with contents:

(defun foo ()
  (and (featurep 'xemacs)
      (blah)))

  -> Warning: the function 'blah' is not known to be defined.

Compare build logs from
https://hydra.nixos.org/build/71888654
https://hydra.nixos.org/build/71888409

Eg search for "defined" in each logfile.
