I considered embedding into relocatable libraries similar to Windows' 
resource, e.g. for versioning plugins etc, but then decided to use an 
easier and more universal method.

I simply put an Ada constructing function into the library. The function 
is exported. The address returned by GetProcAddress or dlsym goes to 
Unchecked_Conversion to an access to subprogram, and here you are.

The obvious advantage of this method over embedding is that the object 
can be tagged of any derived type, which no embedding can do. And you 
can add whatever further initialization or checks you might need.
