5789 /* The following mirrors what is done in xterm.c. It appears to be
5790 for informing lisp of the new size immediately, while the actual
5791 resize will happen asynchronously. But on Windows, the menu bar
5792 automatically wraps when the frame is too narrow to contain it,
5793 and that causes any calculations made here to come out wrong. The
5794 end is some nasty buggy behavior, including the potential loss
5797 Disabling this code is either not sufficient to fix the problems
5798 completely, or it causes fresh problems, but at least it removes
5799 the most problematic symptom of the minibuffer becoming unusable.
5801 -----------------------------------------------------------------
5803 Now, strictly speaking, we can't be sure that this is accurate,
5804 but the window manager will get around to dealing with the size
5805 change request eventually, and we'll hear how it went when the
5806 ConfigureNotify event gets here.
5808 We could just not bother storing any of this information here,
5809 and let the ConfigureNotify event set everything up, but that
5810 might be kind of confusing to the Lisp code, since size changes
5811 wouldn't be reported in the frame parameters until some random
5812 point in the future when the ConfigureNotify event arrives.
