Martin Sebor commented on STDCXX-940:
-------------------------------------

The {{extern}} keyword is there because when we compiled this code with aCC 3, we'd get Warning 933 informing us that the first argument to the {{_RWSTD_DEFINE_FACET_FACTORY()}} macro was null (empty) because {{_RWSTD_EXPORT}} expands into /* empty */ except on Windows (where it expands to {{\_\_declspec (dllexport)}}).
