It's valid C code and does the right thing, so this warning is a false 

To compile without warnings with a recent GCC, you can use:


Other compilers (and older versions of GCC) may need other options. In 
general the code doesn't bother trying to silence all the warnings 
generated by all the world's C compilers, as the job would be endless 
and we might even have dueling compilers. Of course we should continue 
to fix real bugs and obvious howlers found by clever new compilers.
