i found a little time to look into these.  patches like the ones
below, but applied to all 10 of the tests rather than just 2, should
make the problems go away.

I don't really have time to fix them all, but thought you might want
the info...


(OK, the first hunk of each .d file's diff, and the number of 0's in
the second hunk are my personal style preference...  but you get the
idea...  8-)
