[crossfire] Patch for (void)

[Nicolas Weeger]

Hello.

The patch 
https://sourceforge.net/tracker/index.php?func=detail&aid=1660388&group_id=13833&atid=313833 
adds (void) to functions instead of () when no argument.

What do you think of that?

I have mixed feelings, I don't like adding unecessary things. On the other 
hand maybe that's the convention we want to follow?

Nicolas
