...but not for the special case of casting from/to void(*)(void).
(Using the correct function type
> css::uno::XInterface * (*)(css::uno::XComponentContext *, css::uno::Sequence<css::uno::Any> const &)
throughout would be even better, but doesn't easily fit into this C code that is
included in low-level places that don't know those UNO types and is shared
between LOWA and Android etc.)
