I did another test. I checked out Aug. 8 source (right before multi-tty
merge), and reverted mac_set_unicode_keystroke_event as described above.
It builds and works well.
So:
1. The culprit is multi-tty merge
It's reconfirmation to confirmed suspicion.

2. Function mac_set_unicode_keystroke_event should be reverted.

3. I am glad I upgraded my emacs-unicode-2 Carbon port from June 6
source to Aug. 28. 83 days after D-day brought me more peace.
