I pretty much couldn't get ANYTHING related to Object to work, which I 
think was ultimately because thread-local storage was ruining 
everything, and I was spending way too much time on it.
The only thing I got working was pretty much C code written in D... 
structs & unions, fun stuff. :)

I don't remember how I built this... I used the Geany text editor, 
because it also had some (minimal) project support, but I have no idea 
what the command-line parameters and all that stuff were. (I remember 
doing a LOT of work with .obj files and stuff to get everything working, 
though...)

Feel free to try building it, good luck.
I've attached the file (7-zip archive)... let me know if it didn't 
attach correctly.
