// Macro to suppress warnings for clang only. In some cases the
// IGNORE_COMPILER_WARNING is not preferred for both the GCC and clang. For
// example, clang has own warning enabled with -Wall/-Wextra or warning option
// differs slightly (-Wunused-local-typedef vs -Wunused-local-typedefs).
// Use POP_CLANG_DIAGS to remove the diagnostic.
