I agree and I am glad that the people on this forum are always 
willing to help. I will soon be able to write a book about 
interfacing to D (via C) from various languages, ha ha!

Yep, const is next on my list.

By the way, Python could call the functions in the DLL _without_ 
extern (C). The name would be mangled though, e.g.:

lib.D8abairDLL10printThisFxPaZv(...)

It wasn't until arguments were passed to D that the problems 
kicked in.
