To be honest, I don't know. I tried native bootstrapping on x86_64-w64-mingw32 at the beginning of last year but gave up due to the issues found. Lately I managed to bootstrap the 4.6 series with some manual intervention even ada included. There are still issues, one of them is really fundamental, but that's a different story. Btw. the PATH composition for --with-local-prefix is messed up the same way.
