Yeah, you might be right. In some cases we use the libc (maybe GNU)
getopt-long, and in other cases we use our own version, and there are
behavioral differences between the two. The fact you are testing on
CentOS and the other on AIX probably explains it. I think using
/dev/stdin should work on both.
