Turn the Link class into a template abstracting over the link's argument and return types, but provide default template arguments that keep the generic, unsafe "void* in, sal_IntPtr out" behvior. That way, individual uses of the Link class can be updated over time. All the related macros are duplicated with ..._TYPED counterparts, that additionally take the RetType (except for LINK_TYPED, which manages to infer the relevant types from the supplied Member). (It would have been attractive to change the "untyped" LinkStubs from taking a void* to a properly typed ArgType parameter, too, but that would cause -fsanitize=function to flag uses of "untyped" Link::Call.)
