still does not compile using the command from above. I may 
very well be misunderstanding you though.

yep. *both* prototype and real declaration should be 
`extern(C)`. `(C)` part is important too!

I have both the header in hello.d and the actual function in 
getReturnCode.d as extern, and it still fails with the same error.
