  As Jason pointed out, he had fixed these problems - I just hadn't caught
the commit message in source-changes and didn't realize they were fixed.
I was using Saturday's SUP, and after I added the files Jason changed, my
amiga system ran fine.

  Since Hauke Fath indicated that he was using a more recent sup than I
was, the problem I was seeing shouldn't be the same thing.
