================
Comment at: libcxx/include/__config:319
 
+#if defined(_AIX)
+#    define _LIBCPP_BASIC_IOS_HAS_FILL_SET 1
----------------
What about adding an ABI guard around this whole block? Something like:
```
#if _LIBCPP_ABI_BASIC_IOS_HAS_FILL_SET_IF_NEEDED
```
And defining that for the unstable ABI (_LIBCPP_ABI_VERSION >= 2) in the relevant block here? That would let folks not requiring the stable ABI  on the below platforms pickup the fix automatically if needed.
