Tell me you're joking. I hate wineconsole; why should I have to use it when I want to use winedbg?
if you want to have proper Ctrl-C handling, you have to use wineconsole
IOW, winedbg is a winelib app and gets its input from win32 console
feel free to write another input driver (from bare unix streams) which would put the unix-console in raw mode to handle properly the ctrl-c
