Calling conventions don't change. But trying the get I5 or such from a
void function will not work anymore, because arguments and return values
are copied now.

E.g. when you have a sub that ends with:

  set P5, 100 # ret value
  set I0, 0   # non-prototyped
  set I3, 0   # no return value
  invoke P1   # return

then P5 will not be passed to the caller.
