Tested locally and had success with R-devel but not R-release but that may well be due to my R-release being the packaged .deb built with a more conservative g++ version. A local R 4.5.0 should also work with proper g++ or clang++

New R version support C++26. My R 4.5.0 installation has it in its
Makeconf, albeit empty (as supposefly the compiler iot met at configure time for this binary was too old). My local R-devel installation has it, and works with what is proposed here (usingg++-14). Also rolled the micro version as we commonly do to mark small changes such as this and the preceding PR.Checklist
