The branch main has been updated by jhb: URL: https://cgit.FreeBSD.org/src/commit/?id=ec41a96daaa6e401bc0d4ba71d9cf37a1d79fc86 commit ec41a96daaa6e401bc0d4ba71d9cf37a1d79fc86 Author: John Baldwin <jhb@FreeBSD.org> AuthorDate: 2023-07-01 19:21:13 +0000 Commit: John Baldwin <jhb@FreeBSD.org> CommitDate: 2023-07-01 19:21:13 +0000 sys: Switch the kernel's C standard from C99 to GNU99. This matches the default used in userland, and the kernel already depends on various GNU extensions to standard C that are supported by both clang and GCC. This should be a no-op for clang, but for GCC it enables some GNU extensions that aren't otherwise enabled. It also enables GCC for i386 to avoid the need for a floatundidf intrinsic in libkern.
