Exactly. rename(file, directory) produces an error. Some
systems associate the error with the directory and give EISDIR.
Solaris (at least 5.8) associates the error with the file and
gives ENOTDIR.
Looks like SUS declares EISDIR as the correct errno. I didn't
realize that... I don't think it's worth a full compat wrapper
just for this, but I could be wrong.
It is worth including your very lucid explanation in the
routine's comments, though.
