Try it again with the system-provided declarations, rather than the 
classic and old-school 
add-an-external-and-who-cares-about-the-arguments approach.
You'll find the compiler will be recalcitrant.
Replacing these old-style declarations with the system declarations 
might also find latent bugs in existing applications, particularly 
around argument specifications and missing arguments.
I've found all sorts of latent bugs over the years by tightening up the 
code, and by enabling and using compiler diagnostics.
