I guess make doesn't expect ENOENT from readdir as it's not a
documented error code.  This is probably an artefact from the mount
point handling.  It kind of injects the mount point into the parent
directory and then, since the drive is unavailable, an OS call returns
STATUS_OBJECT_NAME_NOT_FOUND, which is propagated up the chain.

I add that to my TODO list for after 1.7.35.
