Fun.  This was already unnecessary at commit 7a2fe9bd0371 which
introduced the file.  It seems Abhijit had that include in his first
version [1] because he was using floor().   Robert rewrote it later [2]
and replaced that with straight arithmetic, making the include
unnecessary, but forgot to remove it.
