    Avoid unsigned/signed comparison in loop condition
    
    The gid_len length is declared as an unsigned int, and loop
    index 'i' is a signed int.  This could manifest as an infinite
    loop if gid_len is very large.  In practice, gid_len should be small,
    but make 'i' the same type for consistency.
