   // Ignore C++11 attributes on declarator chunks: they appertain to the type
   // instead.
-  // FIXME: We currently check the attribute syntax directly instead of using
-  // isCXX11Attribute(), which currently erroneously classifies the C11
-  // `_Alignas` attribute as a C++11 attribute. `_Alignas` can appear on the
-  // `DeclSpec`, so we need to let it through here to make sure it is processed
-  // appropriately. Once the behavior of isCXX11Attribute() is fixed, we can
-  // go back to using that here.

   // Unknown attributes are automatically warned on. Target-specific attributes
