But it seems there is no struct scroll_bar at all in the NS port! (Why

Think Different (tm) :-).
Does anyone want me to
fix that?
I have no opinion on that.

In the meantime, a loop through all the scroll bars in a mark_nsterm
function would suffice.
Please find a patch for that attached.

As an aside, if anyone has heard anything about building GDB on an M1 Mac, I'd be grateful for a pointer. I'm asking because I'm currently stuck with lldb on my machine.  GDB doesn't seem to build - it doesn't produce an executable, but apparently, if I'm not blind, without saying what the problem is.
