MSys2 build not working

[Daedie-git]

Hi,

Thanks for all your hard work you're been doing on modules. It's been incredibly useful in getting started on using them in my clang builds in Linux.

I've gotten stuck on using them on Windows though. I've tried creating a MSys2 (tried ucrt and clang64) build of CppInAction following the instructions and I've gotten stuck on it. I've attached a build log.

build.log

It looks like the version of std::string that argparse adopts through header inclusion doesn't match up with the version i'm getting from import std;. But it's not clear to me why.
