ROL's production of a 32bit Shared CLib for the A9Home is a useful development, and should be welcomed. Its a pity that they could not have come to some arrangement with Castle to obtain the standard 32bit SCL - but given that they didn't/coundn't this solution is a fair alternative.
I am a little puzzled though by the comment about WimpSlot size limitations not being lifted in order to maintain compatibility with RPC variants of RISC OS. Surely any applications will either be 32bit clean (in which case the RPC WimpSlot limitation need not apply - on the Iyonix it doesn't), or the code is 26bit - in which case it *can't run* in which case incompatibilities with Wimpslot size are the least of its problems - alternatively A9 users could use Aemulor which would allow the old code to run (and AFAIK) also limits the WimpSlot to the same as the RPC (a limitation that should *only* be in effect while required - ie., when Aemulor/26bit only code runs).
Why put limits in where none are required (especially when there's a solution at hand - Aemulor)?
