It means that FastTickerV is not implemented in RISC OS 5.

You're probably aware of the centisecond timer, and the centisecond
ticker that drives it.  Without going into detail, RISC OS 6 (and
possibly 4, I don't know) implemented a faster ticker.  I think it
will find its way into RO5, sooner rather than later, but we don't
know how fast ROL's version runs - or if there is any way to set
its speed, enable/disable it, etc.
