There are to angles to this problem. One is of course that, as gcc
reports, we have an unused variable in our code, which we should safely
remove. The other is that gcc treats warnings as errors and fails
because of this. I don't think that this is the standard even for gcc
4.6. You should find out where this is set and remove that setting.
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).
