We started some work in that area, but we haven't had the time to
finish.

There is a little problem of copyright. Theses interfaces are
basically translation in Modula-3 of Motif software; our current
understanding is that the original copyright applies to these
translations as well. (For the X interfaces, this was not a problem are
the copyright comes with a licence that allows redistribution).

We'll try to figure out the details there and follow-up to this
newsgroup with whatever we learn.

Unfortunately, the X includes files are not clean enough to support a
near-complete automatic translation. If you look carefully, you will
discover that the Modula-3 bindings are more precise than the X
include files (that's one of the benefits of type checking).
