--- Comment #2 from Nathaniel Shead <nshead at gcc dot gnu.org> ---
Ah, but we cannot just mark as MK_unique because then we'll clash if a user has
a third TU:
// c.cpp
module repro;
import :part;
void use() {
foo();
}
because it'll need to dedup the type provided from the combined CMI with the
type provided from the partition...
