It is not compiler dependent. There are rules. Within the rules the compiler
will do what is best.
If you need to force him to use a specific calling convetion you can use
"pragma Convention" or "pragma Export" described in the chapter for
interfacing with other languages. But don't do it unless you have too or
for training.
