Thanks Thomas. This would be last resort solution.

I am looking a bit how are  defined other types. It seems that to define
a type,  it must  be supported by  the struct  module (or is  _type_ for
libffi?).

Given the size and  the alignment of a C type (16 and  16 in my case for
x86_64), can I build a  placeholder from _SimpleCData that would enforce
this size and alignment?

Thanks.
