Which version of clang does CRAN's R build use?
The instructions on https://mac.r-project.org/tools/ say to install tools using `sudo xcode-select --install`. Currently for me that installed Apple clang version 17.0.0 (clang-1700.0.13.5) Is that the version of clang that is being used in the CRAN builds? If not, is there an advantage to matching what was used? Duncan Murdoch
