Please switch to a nightly, I've forgotten the history of that warning, but I think it was to do with pointer to pointers.

Nightly has a new declaration parser and can handle arbitrary depths of pointers and fixes all the other idiosyncrasies of sccz80.

There's also rather a lot of new optimisations, some of which should make testing bits in a tcp header a bit quicker
