Well, the variable "outfile" is declared as

        NSString *outFile = nil; 

and is used inside the loop while. But for some reason (I don't know how
the compiler works) show the previous error. Of course, I can compile
GUI removing the option -Werror in GNUmakefile of tool "say".  And I
don't know if this option is really necessary here (I think no).
