Tee hee... It compiles, let's ship it!

I found that macro today, and I'm trying to get things working right with
it. It's way neater than the generated code, which makes me feel more
comfortable. It also doesn't rely on the included generated C code from
orbit-idl.

I didn't think it was either, but I also didn't know how to make it right. I
thought I had it mostly worked out today, but...

Heh. Check out page 56 of "The Common Object Request Broker: Architecture
and Specifications" for an example of C++ code where the return types from
create_recursive_tc() and create_value_tc() seem to be a TypeCode_var.

I'll modify the prototypes to match what you've suggested, for two reasons:
1) It will match the C++ mapping correctly.
2) I can't get it to work using TypeCode_var return types anyway. :)
