yup.

function AlphaByte(x : byte) : byte;

end;
note, in the C++ code, X can be a short, long, whatever....

Ouch - I think that forces stack push and pop's to align to 8 bytes. Not
sure tho. Depends if you are porting the code over, or just interfacing with
the DLL.

Not really - if it doesn't work, there is not a lot you can do. If its
passing objects around, you are very definatly SOL.
