    Minor cleanups relating to size_t being unsigned
    
    In order to use -1 as a sentinel value, we should explicitly cast
    to make it clear what we are doing.  It might be better to use
    a less convoluted sentinel value such as SIZE_T_MAX, though.
    
    Additionally, since size_t is unsigned and at least as wide as
    an int, a loop with int index variable that compares against a
    size_t for its termination check could become an infinite loop.
    Make the loop index size_t for consistency.
