Hi guys,

Thanks, Thomas for raising the PR it is currently being merged. We will raise the next PR to get bootstrapable builds working which will be really nice there is a GitHub automation for that at the moment.

Something I was thinking about outside of the scope of that patch was about the utf8 how do they get represented? Is it some kind of wchar_t?

Thanks again

--Phil

Ah, sorry, I don't really track the github issues and had missed
those. But good to see the analysis matches.

To make --enable-bootstrap possible (wow, that takes a long time...)
you'll also need:
https://gcc.gnu.org/pipermail/gcc-rust/2021-September/000178.html
https://code.wildebeest.org/git/user/mjw/gccrs/commit/?h=rust-mangle-unreachable

With this and that patch applied there are no more warnings building
the rust frontend, so a --enable-bootstrap (-Werror) build completes
successfully.
