--- Comment #4 from Joachim Protze <protze at itc.rwth-aachen.de> ---
Yes, the dependencies seem to be fixed.
I guess, what I had in mind while writing comment 2 is that making
schedule(static,1) the default for do-across loops might typically provide
better results (instead of distributing blocks of rows).
>From my test, this is what gcc and icc do.
