The funny thing here is that if we just add the parameters, then on
systems with "standard" calling convention old programs should run
without any problems with newly compiled shared libraries: The new
library functions will expect one parameter that is not actually there
and will take whatever happens to be on the stack and pass it to the
callback function as a "pointer argument"; the callback function in
turn just ignores this extra (garbage) argument.
