More digging around in sdl.c revealed that SDL on Linux returns X11 keycodes
as GTK on Linux does, while on Windows SDL returns the raw scan code.

I've cleaned up the code a little bit, and attached a new gtk2.c to this email.

Since no Win32 person on this list or in the qemu irc channel offered to help
me,
I can not even guarrentee this will compile. And if it does compile, it is
possible
that keys will not work right due to lost of information due to casting (this is
unlikely as all scancodes can be represented as a single byte, and it seems all
Windows virtual key codes can be represented in at least two bytes).
Still, I work with what I have to go on. Try this gtk2.c and report any errors
(be they compile errors or runtime errors or keyboard problems). Your help is
always greatly appreciated.
