--- Comment #3 from Nathaniel Shead <nshead at gcc dot gnu.org> --- Yeah, the warning should only happen if the internal linkage can from the importing language, to find cases where we've treated a TU-local entity in that interface TU as non-TU-local. This should only happen if it was declared in the GMF but that should be by construction, which this bug shows is not happening. There will be a fix but it may take me a bit to work it out!
