With Emacs -Q I can evaluate
(set-window-scroll-bars nil 0 nil)
to remove the scroll bar from the *scratch* window keeping the window
size unaltered. When I now evaluate
(scroll-bar-mode -1)
the width of the frame shrinks and with it the number of columns used
for text in the *scratch* window. This doesn't make sense.

Fine. I wasn't entirely sure about
dos_set_window_size (&newheight, &newwidth);
which IIUC does adjust the width value via
*rows = ScreenRows ();
so this eventually does get related back to the frame's root window.
