I'm looking at this in backporting to 8u and this change seems odd:

~~~
-https://sourceforge.net/p/giflib/code/ci/master/tree/openbsd-reallocarray.c
+tree/README
~~~

Is it really intentional to remove the URL? Should the new line not be:

https://sourceforge.net/p/giflib/code/ci/master/tree/README

and then:

https://sourceforge.net/p/giflib/code/ci/master/tree/openbsd-reallocarray.c

further down? Especially as it says "There have been many other contributors; see the attributions in the version-control history to learn more." and this is removing the link to the version control system.
