    Replace strndup() with strdup() for compat reasons
    
    This is the only thing preventing successful build for MingW on Vista.
    
    Also fix the default port, if only a plain hostname was supplied in the
    CHICKEN_DEBUGGER environment variable.  Before, it would have been
    reading an uninitialized variable and always copying the full string as
    a host name due to an unintended cast to unsigned because of a bad stop
    condition in the loop.
