Nathaniel Shead <nshead at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |nshead at gcc dot gnu.org Resolution|--- |INVALID Status|UNCONFIRMED |RESOLVED --- Comment #2 from Nathaniel Shead <nshead at gcc dot gnu.org> --- This is working as-specified; the "using namespace"-directive has been exported, but exporting this just affects name lookup in importers and doesn't actually export any new names. For that you would need to e.g. `export using x::f;` as well.
