No, there have never been summaries.

It's just AIX interpreting the error condition differently. I think
POSIX permits both interpretations. Since bash just prints the error
message corresponding to errno, and the test is ensuring that the shell
prints an error message on this condition, it's dependent on what the
system call returns. I don't think it's worth trying to work around it.
