The benefit of this function over free() itself is so small... Is it really
useful to put this function into nearly every GNU executable?

I'd have less objections if you would declare the function inline in the
header file, or drop the function and instead write
  #define XFREE(Var) ((Var) ? (free (Var), NULL) : NULL)
