This part should look like this:

  * lisp/emacs-lisp/comp.el ('native-comp-compiler-options): New option.
  (native-comp-driver-options): Rename to 'native-comp-backend-options'.
  * list/emacs-lisp/bytecomp.el: All users of 'native-comp-driver-options'
  changed.

  * src/comp.c (Fcomp_native_backend_options_effective_p): Renamed
  from 'Fcomp_native_driver_options_effective_p'; all callers changed.
  (Fcomp_native_compiler_options_effective_p): New function.
  (add_driver_options): Remove WINDOWSNT condition.
  (add_compiler_options): New function.
  (Fcomp__compile_ctxt_to_file): Call 'add_compiler_options'.

IOW, you need to list not only the files, but also the functions and
global variables that you change.

This will be much easier if you use "C-x 4 a" or "C-c C-d" (the latter
in the VC log buffer): they will generate the skeleton with file name
and function name for you, so you need just add the description of the
change itself, what's after the colon.

(I can fix the log message for you this time, if you are exhausted ;-)
