The branch main has been updated by ivy: URL: https://cgit.FreeBSD.org/src/commit/?id=036ff38ebd5a52f26fc2f20238a492a9d0c5f2e6 commit 036ff38ebd5a52f26fc2f20238a492a9d0c5f2e6 Author: Lexi Winter <ivy@FreeBSD.org> AuthorDate: 2026-04-27 21:31:47 +0000 Commit: Lexi Winter <ivy@FreeBSD.org> CommitDate: 2026-04-27 21:31:47 +0000 libzpool: Set -Wno-error=typedef-redefinition for clang In some versions of LLVM (at least 21), the <*intrin.h> headers contain unguarded duplicate typedefs; this isn't permitted prior to C11, and libzpool is built as C99. FreeBSD's LLVM backported LLVM PR #153820 to fix this, but other versions of LLVM (e.g., upstream, or on Linux) don't have the patch, so this breaks the build. Add -Wno-error=typedef-redefinition to downgrade this from an error to a warning.
