In that patch, one of the removed requires wasn't redundant.  The
following temporary fix got me building again with native compilation:


diff --git a/lisp/emacs-lisp/comp-cstr.el b/lisp/emacs-lisp/comp-cstr.el
index 82d48e59a23..6751e7ab0a7 100644
--- a/lisp/emacs-lisp/comp-cstr.el
+++ b/lisp/emacs-lisp/comp-cstr.el

 ;;; Code:

+;;;; TEMP STOUGH, 2023-10-31
+(require 'cl-extra)
+;;;; END OF TEMP STOUGH
 (require 'cl-lib)
 (require 'cl-macs)


No doubt it will get fixed properly, soon.
