Verify correct d_type values of dir enrties. This test would fail for file systems with no d_type support, but I have no idea how to test d_type support in a generic way, without confusing a bug of d_type = DT_UNKNOWN with no support. I wonder if anybody is interested in testing a file system with no d_type support.
