I want to build a project I have, which has to link against Boost.System, to WebAssembly, and it seems like I have to generate LLVM bitcode for it first.  Is it possible to use the bootstrapper that comes with the Boost distribution to do this on Windows 10?

The project in question is on GitHub here: https://github.com/DragonOsman/currency_converter .  I switched out the Asio in the Boost distribution with the official Emscripten port of Asio, found here: https://github.com/emscripten-ports/asio .  But I don't know which version of Boost.Asio it's using so I'd like some clarification on that if possible (I opened this issue there: https://github.com/emscripten-ports/asio/issues/2 and have just now updated the question to ask what version of Asio is being used for the port).
