Bug#472315: improper getopt() usage

[Ulrich Eckhardt]

Package: barrage
Version: 1.0.2-1

In main(), there is 

  char c;

  while( (c=getopt(..)) != -1)

which falsely assumes that char is signed. Just replace 'char c' with 'int c' 
and it will work on platforms where that is not the case, like PPC.
