Ah, thanks.  That helps a lot in figuring out what the code actually is.

I get the same in my gcc:

      matrix->window_left_col = (((((long) ((w)->left_col)) >> (3 - 1))));

So the warning is incorrect -- it's no longer a Lisp_Object at that
point.  But it's correct in that it's a potentially problematic
conversion.  (But probably isn't in actuality, since it's unlikely
w->left_col really is a more than 31 bits.)
