C is honestly terrible to target/use as FFI, doing so precludes doing things correctly, or more advanced things like... say arrays that "know their own length" or numeric-types that are range-constrained.

There's a fair amount of C code that does just that and does it for a long time.

Those don't need astral and can be passed through C ABI just fine.

No, there isn't.
There can't be because of how arrays in C degenerate into pointers/addresses; see Walter Bright's "C's Biggest Mistake" -- here: https://www.digitalmars.com/articles/C-biggest-mistake.html

No, they can't.
If you're passing a "Positive" through C's ABI you lose the fact that the value can be neither negative, nor zero. (Unless you mean "passed through" as in, "not mangled", but this is setting the bar so low as to be laughable.)
