Seeing the number of times getCppuType is used, I've got several questions about this: - what's the use of it? It resembles at the first look to "typeid" but I suppose it's not this.
Yes, it's to the C++ UNO language binding what typeid is to C++, mapping from a C++ type representing a UNO type to a css::uno::Type instance describing that UNO type.
getCppuType is not without flaws though, and cppu::UnoType should be used instead.
- could there be an alternative? (eg a more "native"/straightforward C++ way)?
Not really.
- if it still must be used, could the C style cast be changed in static cast (to be sure the cast is in build time and so the check is also in build time)?
What cast are you talking about? The one in the typical usage like getCppuType((T*)0)? Sure, nothing keeps you from writing that as getCppuType(static_cast<T*>(0)), or better yet, cppu::UnoType<T>::get(), instead.
