I don't have any experiences with H2D, but I played around
recently with H2O and Swig. Both have pros & cons but could
be a solution for atomagically generating interface modules:

1. Swig http://www.swig.org/

Swig is a interface & wrapper generator for C and C++
header files. There is currently a language module for
Modula-3 interfaces, which can be adopted. I started/tried
(successfully) to derive an OberonCP language module,
which is currently not really anything more than a
rename of the Modula-3 module. Swig is written in C++
and the code is readable. Swig was primarily meant to
generate C wrappers for scripting languages. There is
a lot of documentation, many examples and a test suite ...

2. H2O is part of the OO2C compiler.

It is almost undocumented (except the short intro Stewart
gave me some time ago included below) and (ofcourse) the
complete source written in Oberon-2 (with some extensions
for OO2C like namespaces and using the OO2C libraries).
You can browse the source code here:
http://ooc.cvs.sourceforge.net/ooc/ooc2/src/H2O/
Afaik, there is no main program except TestH2O, which is
here:
http://ooc.cvs.sourceforge.net/ooc/ooc2/src/TestH2O.Mod?revision
14&view=ma
rkup

I currently have problems wiht getting OO2C compiled under
MinGW and Cygwin (on different PCs), but I am working on
it (when time permits).

Summary: Both are options, both need work ...
