The definition of TC_Bonobo_Unknown_struct should be in the C stubs
generated from the same IDL file.

The simple "Hello World" example I just compiled placed those struct
definitions in the helloworld-common.c file.

I've found a mention in section 1.32, which says that for each type, the
implementation must provide a TypeCode_ptr called _tc_<type>. It gives
details on scoping and naming as well.

The TC_<type> TypeCode constants are part of the C mapping. The _tc_
prefix is used in the C++ mapping to avoid clashes with the C mapping.
