I agree - readdir should ALWAYS match stat, even in the face of
mount points, if it is going to provide d_ino.  Even cygwin developers
took great care in their upcoming 1.5.20 release to ensure that
mount points are handled correctly, such that readdir reports
the same value that stat will provide.

Is there an easy configure or runtime test we can do to detect
buggy readdir implementations, and always do stat on those
platforms?
