IIUC, the problem only manifests while *building* the release candidates, not for users of the release candidate. For 4.2, my suggestion is to just use a bootstrap4 while building the RC. For 4.3, we can use --enable-stage1-languages=all when building the RCs. I can prepare a patch to do that automatically when --enable-generated-files-in-srcdir is passed. Paolo
