Ok, I didn't do it in general for inductive types but just for an example.
The rest I planned to do in a journal paper, still forthcoming... :-)

But the basic idea is explained here:

@InProceedings{alti:types94,
author = "Thorsten Altenkirch",
title = "Proving Strong Normalization of {CC} by Modifying
Realizability Semantics",
editor = "Henk Barendregt and Tobias Nipkow",
series = "LNCS 806",
pages = "3 - 18",
booktitle = "Types for Proofs and Programs",
year = "1994",
}
