I didn't reproduce the warning, since I lack GCC "13.1". I merely looked 
at the Gnulib source and noticed a couple of places where it was not 
conforming to the C standard.  I have enough knowledge of GCC internals 
that I think I've changed the code so that it will pacify GCC "13.1".

Although the updated code still doesn't conform, it should work fine on 
real platforms. (The old code probably works too, for what it's worth.)
