I'm not 100% sure what you mean with compile+link in the modules. 
The structs are all defined in the original (third party) C 
header file. It's nothing I added (in which case I would have to 
recompile the C library). The C structs in the C library should 
be visible to the linker, shouldn't they? Just as when you define:

extern (C): size_t strlen(const char *str);

and the linker will find it automatically. The error I get is as 
if the structs were not defined (or as if the lib weren't linked 
to).
