================
Comment at: libcxx/include/limits:342
     static _LIBCPP_CONSTEXPR const bool traps = false;
+#if (defined(__arm__) || defined(__aarch64__))
+    static _LIBCPP_CONSTEXPR const bool tinyness_before = true;
----------------
Instead of each of these ifdefs could we maybe do something like

```
#if defined(arm or w/e)
#define _LIBCPP_TINYNESS_BEFORE true
#else
#define _LIBCPP_TINYNESS_BEFORE false
#endif
```

Then we can undef it at the end of the header.
