Now that I have the osicat tests running in Lispworks/OS X, I'm looking at the failing tests.

The first one, current-directory.1, is failing because

(pathname "/tmp")

produces a pathname with nil components other than for the directory, while

(truename "/tmp/")

produces a pathame with the non-directory components set to :unspecified.

This doesn't seem wrong to me. I think the best fix would be to change the test, so that it does

(equal (truename (current-directory)) (truename "/tmp/"))

That should be applicable to all (Unix) platforms.
