Actually, I'm pretty sure it does that for vararg too. From what I
understand the calling convention of vararg functions and regular
functions *must* be the same for the C calling convention because a
function declared in C as e.g. "int foo()" (or more commonly, not
declared at all) is treated as vararg but may later match a definition
with a different prototype, including "int foo(Struct) { ... }".
