ReproducibleScript:
Working on Wish for Win95:

% menu .m
.m
% menu .m.system
.m.system
% .m add cascade -menu .m.system
% .m.system add command -label Hello
% . configure -menu .m
(Observe new "Hello" entry in system menu.)
% . cget -menu
.m
(Confirm Tk knows about menu.)
% wm overrideredirect . 0
(I would expect this to be a no-op, but
observe that "Hello" entry has disappeared from system menu.  BUG!)
% . cget -menu
.m
(Tk thinks menu is there... but it isn't displaying it any more.)
% . configure -menu .m
(Observe that this doesn't fix it.)
% . configure -menu {}
% . configure -menu .m
(This pair of operations successfully restores the additions to the system menu.)



Verified that something really screwy is going on in 8.3b1.
The 'wm override' does cause a loss of the system menu additions.
It also causes . to increase in size with each call.  Clicking
on the system menu after it disappears caused . to disappear on
me, but you can reconfigure it otherwise.

Partial fix in 8.3b2 - 'wm override' will not do anything unless
you are really changing values, becoming a true noop in the above
case.

Merged into main, core-9-0-branch, and core-8-6-branch by commits [88bdbe4c] (Jan), [030f83d2], and [d21c812c]. Closing the ticket.

Still present on Windows 11 with 8.6 and 9.1: "wm overrideredirect . 0" is a no-op now, but a real change of the value recreates the wrapper window and the additions to the system menu are lost, as noted above. The ".system" menu was bound to the system menu of the wrapper only once. Fixed on branch win-sysmenu-wrapper in [dcd20365e5]: the menu is rebound to the system menu of the new wrapper.

Also dupped by 587698, it is still a valid problem where the 
wrapper window isn't updating the system menu when it is 
recreated in tkWinWm.c:UpdateWrapper.

still valid?
