What I need is an "entry" function that I can call. The functionality
provided by build-shared-library is of no use to me. My code looks
something like:

void init_plugin(...)
{
        cl_boot(...);

        /* Initialise wrapper functions */
        /* and some variables */
        wrap_functions();

        /* Load the definitions from the lisp object */
        init_list_part();

        return;
}

The main problem is that init_plugin is the entry function that is
called when the shared library is loaded. 
Looking over the code I guess one could add a :init-function keyword
parameter to the builder function and have it construct a function
that I can call whenever it suits me.

I understand, but I do not believe that it is usable for shared
libraries as is.
