WFM under XP with fileutils 4.1-2 and any one of cygwin dll 1.5.7 and the
last two snapshots (20040306 and 20040312).

I can re-create the error if I create a hard link in ./bin as shown in the
second example below:

$ echo aaa >foo
$ mkdir bar
$ cp foo ./bar/

The above works fine, but the following fails with your same error:

$ echo aaa >foo2
$ mkdir bar2
$ ln foo2 ./bar2/foo2
$ cp foo2 ./bar2/
cp: `foo2' and `./bar2/foo2' are the same file

You might check to ensure there is not a link in ./bin pointing to the same
file in the parent directory.
