I've done that now and could successfully bootstrap on macOS 14.0 beta 3 with Xcode 15 beta 4. Thanks for the patch, especially since my patch series to consistently prune the ld warning provded to be a can of worms. I needed one patch to link m2/boot-bin/mklink with -static-libstdc++ (to be submitted shortly). However, there's an enormous number of issues compared to macOS 14.0 beta 2/Xcode 15 beta 2, in particular all (?) EH-related execution tests failing, and all gfortran tests failing due to ld warnings about duplicate libraries (will submit a PR for that).
