The [-Wno-extra-semi] is already disabled in the build. This change will allow the build to remain consistent across newer versions of clang which are now issuing a new similiar warning [-Wextra-semi-stmt]: https://clang.llvm.org/docs/ReleaseNotes.html#major-new-features https://clang.llvm.org/docs/DiagnosticsReference.html#wextra-semi-stmt PiperOrigin-RevId: 225185101 -- f7fd6244b4efcf0331631a54b7b0cf5f1f691a89 by CJ Johnson <johnsoncj@google.com>: Move using directive in swap implementation PiperOrigin-RevId: 225017825 -- 3005841725df5b9cdb35c8a5319bb4c78b5dc2b7 by Abseil Team <absl-team@google.com>: Update absl/strings/CMakeLists.txt to use new functions i.e. absl_cc_(library|test) PiperOrigin-RevId: 224860689 -- eeaf7099924b182472bfea3636ef6d9a39adfc50 by CJ Johnson <johnsoncj@google.com>: Prefer public method over private for InlinedVector allocator access PiperOrigin-RevId: 224825775 -- db9d218e3ca7ab400eef97778b720cb082a03281 by Eric Fiselier <ericwf@google.com>: Take advantage of secret libc++ resize uninitialized function in string.
