There are actually quite a few examples of nontrivial interfaces to C.
Go to almost any Ada site (http://www.acm.org/sigada/,
http://www.adapower.com, http://www.adahome.com) and look for
Ada bindings.

The one I wrote is an Ada binding to Tcl/Tk, see http://www.adatcl.com.

Right now, it has two levels of binding:

1) a thin binding to the C objects and functions using predefined Ada
    types which match the C types, and

2) a slightly thicker binding which uses Ada types in place of C types
    and exceptions instead of return codes.

I'm currently working on a thick binding which non-Tcl Ada programmers
will find much easier to use.
