This is no option.

Offer the strong typing features by declaring each argument count as a
seperate function/procedure. Import those from the same linker name. This is
recommended in the ARM. It works. If you need also variable argument types,
use generics for Import.

If you need to provide such a function, you have to use a completely
different approach: You have to have a deep look into the calling system of
your other world compiler ...
