would it work on emscripten? or lots of function pointer casts prevent?

[bkerin]

I gather emscripten doesn't work well with C code that contains many function pointers casts (and such are not actually defined behavior in C).

Does COS target emscripten ok?

[Laurent Deniau]

I don't know, COS uses a lot function pointers and store them. Casts are not so frequent.
