I think it would have been a magnanimous gesture by Castle to have allowed their existing Shared C Library to have been distributed with the A9. I frankly doubt that many people do not have a valid licence for it (you get one from a developer who distributes code that relies upon it) and it would have been a low (no?) cost contribution to the market as a whole.
It does no-one any good that scarce developer time is spent duplicating basic resources. It may be politically impossible to stop people duplicating the 32-bit OS but, surely, something like this is not damaging anyone's position
