digitalmars.D.learn - Derlict binding with out_of_link_module struct definitions

Wow, sometimes tough to find a good subject and issue description.
I am working on a dynamic binding to the mantle32.dll following 
DerelictGL and DerelictCl.
Functions in the mantle dll use structs as argument types. I 
would like to define those structs in a module 
derelict.mantle.types ( as in DerelictGL/CL ) and import them in 
module derelict.mantle.mantle. Module mantle does have the 
required hooks:

import DerelictUtil;
import some_other_module_which_needs_the_struct_definitions;

// struct definitions required
class DerelictMantleLoader : SharedLibLoader { ... }

Unfortunatelly I get an optilink error telling me that the 
required structs are undefined.
Putting the struct definitions back into module 
derelict.mantle.mantle does work, but this is not an option as it 
will lead to cross import issues later on. The structs are also 
required in module some_other_module_... and that module ( which 
should handle mantleExtensions ) must also be imported in module 
derelict.mantle.mantle.

I tried using opaque structs in module mantle which also didn't 
work.

How can I have those structs have defined in a different module 
than that which is linking to the dll ?

Is the source code so far up somewhere with the errors being given?

Nope, only a working version with all the stuff in one module, 
git DerelictMantle.

I created a version tag-less branch with the described issue and 
linker problem:
https://github.com/ParticlePeter/DerelictMantle/tree/ExtensionSupport

A test project using DerelictMantle can be found here:
