Is the triple wasm32-wasip2-threads going to be a thing? I believe clang will set _REENTRANT for wasm32-wasi-threads but for wasm32-wasip2-threads will clang just set nothing
I don't believe so; the earliest we'll see support for multithreading in the component model will be in the WASI 0.3.x timeframe for x > 0. And note that wasm32-wasi-threads as it exists today is an experiment and is not on track to be standardized.
