  The file you are changing is not go32v2 specific, thus
if a change is only for the go32v2 target, we need to
add a target test for the given change.

  The problem is that very long line have problems with
editors (like fp for instance...) that is why the splitting was introduced,
I don't understand the advantage of removing that.

 Why is this glbal modifier needed?

  Could you please explain the reason of that change?
