[issue16575] ctypes: unions as arguments

[Eli Bendersky]

Eli Bendersky added the comment:

A minimal fix would be to update the documentation.

A more comprehensive fix would be to tweak ctypes to reject unions and bit-fields when running on non-x86 (does this work for ARM and other non-Intel archs?)

An even more comprehensive fix would be to make this work, but that would require forking libffi and should presumably be first implemented upstream.
