Keyboard Layout

[Altan Íz³dogru]

My computer works with Linux 8.2. I have tried to install (to execute) a 
Windows Program on my Computer. The wine-program started and 
the windows sreen appeared. Suddenly the programm stopped and I 
got the message:

Your keyboard layout was not found!
             Using closest match instead (German keyboard layout without
             dead keys) for scancode mapping.

Please define your layout in windows/x11drv/keyboard.c
             and submit them to us for inclusion into future Wine releases.

I don´t know how to define my keyboard layout. It would be very nice, 
when you could explain me how to define my keyboard layout.

Thank You
