You can link both libstdc++ and libwinpthread statically if you want. Both libs come with msys2, so I wouldn't really call them obscure third-party DLLs... In practice, threading is not a problem at all with gcc on Windows. I agree, however, that libwinpthread is not the most efficient implementation (that's why I roll my own), but for most purposes it's good enough.
