I'm not familiar with Fortran. How do they do it?

Right... AFAIK, they still do it that way, with a couple exceptions - 
"wsprintf", I think... probably more...

Unless I'm mistaken, changing ".model flat stdcall" to ".model flat C" 
would automatically adjust your code... with certain assemblers...
