Those are gnulib's tests to exercise detection of stack overflow.
That they fail on AIX need not delay diffutils release.

This means that those hosts do not work as expected when we tell diff
to read from a closed standard input (or that the shell fails to do
what "<&-" is specified to do). This is the behavior we expect (exit
with status 2):

  $ touch a && diff --unidirectional-new-file a - <&- > out
  diff: -: Bad file descriptor
  [Exit 2]

I've just adjusted that sub-test to also require that "out" be empty.
If someone wants to investigate, that would be nice:
 - if it's a shell problem, we may want to work around it
 - if it's a kernel or libc issue, it'd be good to know

Consider running these commands with different shells:

$ echo |cat - <&-
cat: -: Bad file descriptor
cat: closing standard input: Bad file descriptor
[Exit 1]
$ echo |head - <&-
head: error reading 'standard input': Bad file descriptor
head: -: Bad file descriptor
[Exit 1]
$ echo | grep - <&-
grep: (standard input): Bad file descriptor
[Exit 2]

Either way, this need not hold up the release.

Quite a menagerie.
Thanks for all of that testing!
