It seems like standard filesystem behavior to me.  Based on my reading
of the MS doc you linked, UNIX filesystems work the same way.

In that case, your makefile is broken ;-).

I don't think the current behavior is incorrect, and I don't think it
needs to be fixed.  After all, you could get identical behavior with
files, rather than directories, if you set your makefile up that
way... so don't do that :-).
