I didn't write that.  But the answer seems pretty obvious: report it to
wherever is appropriate for errors on the file in question.

Typically an error from close() will be something like a delayed-write
I/O error, something the file writer quite likely wants to hear about.

Of course, there also are plenty of uses of close for which the return
value is of no interest whatsoever, such as closing a readonly input
file.
