This is for rust-winapi and the like? Unfortunately IIUC, that's
currently not yet possible in general, because Cargo requires optional
dependencies to be available, see
<https://github.com/rust-lang/cargo/issues/4544>. Unless the
Cargo.toml are patched appropriately as well.
(I don't know if this applies to dev-dependencies as well, or only to
'dependencies' ...)
