The branch main has been updated by dim: URL: https://cgit.FreeBSD.org/src/commit/?id=45feade38ec3e8e30086dedc6ee81cbf816293e3 commit 45feade38ec3e8e30086dedc6ee81cbf816293e3 Author: Dimitry Andric <dim@FreeBSD.org> AuthorDate: 2021-08-26 15:36:03 +0000 Commit: Dimitry Andric <dim@FreeBSD.org> CommitDate: 2021-09-13 16:05:43 +0000 Add -Wno-error=unused-but-set-variable when building with Clang 13+ This warning triggers many times while building world. Downgrade it to a warning until all occurrences have been fixed. Once the Clang warnings have been fixed we should be able to turn it on for GCC as well. See also f4fed768bba45a406f73ed1491d7e52fd1a8711d which did the same for the kernel builds.
