Many thanks for this tip! That'll be a way to try out at least as an
intermediate step. I've already checked that my mini-example runs
through with the C target, and it does. Now I'll have to play around how
to compile the generated code (study README under lib/C, library
dependencies, if any, file order etc.) with gcc, but that should
hopefully not be much of a deal.

Best regards,
