Are sturcts currently always returned on the stack?
From: http://dlang.org/abi.html, for Windows x86 extern(D):
* 1, 2 and 4 byte structs are returned in EAX.
* 8 byte structs are returned in EDX,EAX, where EDX gets the most
significant half.
* For other struct sizes, the return value is stored through a hidden
pointer passed as an argument to the function.
