Subject: r6187: 1. Make sure that we don't try to delete . and .. in a more
 portable way.

2. Also, don't try to delete directories.

I am not entirely happy with this patch, and the fact that there is a
define for HAVE_SYS_STAT_H suggests that there are some systems for which
stat will not be defined, which means that the patch is not entirely
portable.
(This used to be commit fe7ddad7d44a49b2efe81cb3d0a5b2d09d1892ab)
