Yes, Raja is correct and explained it better than I did originally.  I
fixed all the *-expect-errors files that he mentioned and will be
commiting in after make compiler-tests finishes, (I had been using
just make run-test in mcs/errors).  I have to say it is a little
tedious to have to modify 4 different files for each of these that
were incorrect, but perhaps it is not worth worrying about too much. 
Also, should we sort them by number or something, so they aren't
accidentily duplicated and easier to find.

I also have noticed some of the cs8*.cs tests seem to be either yield
tests that look incorrect and have equivalent working tests, or
generics tests that pass with gmcs, can someone in the know look at
