On certain architectures we get a warning about comparison between different signedness integers in fwd_probe_ephemeral(). This is because NUM_PORTS evaluates to an unsigned integer. It's a fixed value, though and we know it will fit in a signed long on anything reasonable, so add a cast to suppress the warning.
