stdcall functions restore the stack while cdecl functions leave this
task to the caller. You cannot have stdcall function with variable
number of parameters.

FB calls the UDF passing the max number of allowed parameters, and not
only the number of parameters declared. Otherwise it would need
hardcoded calls to function with 1, 2, 3, etc number of parameters or
generate assembly on the fly.
