CORE-17545
No other public header out there (in MS PSDK, MinGW, Wine, etc...) does have
this hack (that was introduced back in the days in r15141 / commit 01df92bc).
Add static assert on KEY_EVENT_RECORD's uChar member to ensure it's properly aligned.
May fix Clang warning:
win32ss/user/winsrv/consrv/lineinput.c:457:62: warning: taking address of packed member 'uChar' of class or structure '_KEY_EVENT_RECORD' may result in an unaligned pointer value [-Waddress-of-packed-member]
LineInputEdit(Console, (Overstrike ? 1 : 0), 1, &KeyEvent->uChar.UnicodeChar);
^~~~~~~~~~~~~~~~~~~~~~~~~~~
and whatnot...
