I don't own any windows machines so had to use these references 
(and could not test anything):
- WinSDK10: goo.gl/m9DjZt
- MARS: goo.gl/Qoc6g2
Code above does not yet cover the Mars case, but the i386 sizes 
should be the same.
Please Note: setjmp/longjmp should only be used in "@system + 
@nogc + nothrow / -betterC" code.
