There was a problem hiding this comment.
I think the idea made sense to me but initially it was a bit unclear why the comparison test for expected/wasm32-wasi/predefined-macros.txt was not failing: if we unconditionally #define these PTHREAD_*_INITIALIZERs then I was expecting a diff error. But no: pthread.h is already omitted entirely when THREAD_MODEL=single in the top-level Makefile so these will only be defined when THREAD_MODEL=posix. And they will always be defined then, which I think is what we want. LGTM!

It looks like
defined(_REENTRANT)was added here and it was just to mark these as modifiied. (@sunfishcode would know for sure.)With this change I can build libcxxabi, libcxx, and boost with threads enabled, and link a few binaries (that do not spawn threads, but use mutexes).
