Well... I did not even know that these classes exited until I made
the patch at #5685 (still awaiting review) and had to adjust a couple
of functions in one of those files. I can guess: it somehow adds
+infinity and -infinity to ZZ in a way that makes as much sense as
possible.
But search_src("ExtendedInteger") only picks up these two files, which
suggests to me (maybe wrongly) that they are not actually used
anywhere!
