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.
