Comment (by knarf):

 You could declare it where it is set, but I believe this would not help
 with the warning. The variable is already always set at the moment, but it
 even though it is set, it is never used (only in code which the compiler
 never sees). So - setting a variable to some value doesn't make it 'being
 used', because it never has the chance to change the outcome of the
 function in any way.
