I'm not quite sure what you are telling me here.

Since this code is in hw/xwin, it's only ever going to be compiled for Windows
targets, anyhow.

Since raise() is in C89, I hope systems that it isn't available on are rare :-)

(Also, it looks like I made a mistake when writing the comment, as it should
say "use raise() instead of kill()" to match the code)
