They simply don't change such functions? Or grep through the sources and 
adjust all call sites? The thing is they *know* that adding an 
additional parameter in front of the variadic arguments is a bad(TM) 
idea. For Pascal developers they know that one *can* add parameters, 
because there are the [] after all. It's a different mindset.
