Thanks a lot for the update. I see it's still required to use -frust-incomplete-and-experimental-compiler-do-not-use - for GCC 13.1 I would suggest to instead discourage from distributing rust in the documentation and release notes. Do you expect enough progress until GCC 13.2 (which should be about two to three months after GCC 13.1 is released) so that libcore can be compiled? If not then I'm not sure it makes much sense to keep rust configurable for GCC 13. On the general note - were you planning to keep the GCC 13 branch copy of rust up-to-date with the GCC 14 trunk?
