Thanks.  Actually, POSIX is wrong and Linux is right.  An effort is
being made to fix this at the POSIX level.  See, for example:

http://www.opengroup.org/sophocles/show_mail.tpl?source=L&listname=austin-group-l&id=3736
http://www.opengroup.org/sophocles/show_mail.tpl?source=L&listname=austin-group-l&id=3738
http://www.opengroup.org/sophocles/show_mail.tpl?source=L&listname=austin-group-l&id=3740

That will take time, though, and there's no guarantee that POSIX will
get fixed.  In the meantime, I'm simply going to change:

> !       if (errno != EPERM)

to:

> !       if (errno != EPERM && errno != EISDIR)

since there's no reliable way to detect the compatibility problem at
'configure'-time.
