I have sent the signed paper to assign@gnu.org today and am awaiting
their answer.

What I meant with this question was not whether every file should have a
ChangeLog but rather whether I should add a new ChangeLog entry when
there already is a ChangeLog entry from the original patch.
For example the ChangeLog from the original patch already says that a
new declaration was added to stdlib.h, do I also need to create a new
ChangeLog entry saying that I added #ifdef __USE_GNU?
