The 'pascal' keyword actually became a no-op in the transition to
PowerPC more than ten years ago. It specified whether arguments

registers, 'pascal' is meaningless in the PowerPC ABI.
With enough function arguments — or the right combination of types of
function arguments, if I remember correctly — PowerPC still requires
arguments to be pushed onto the stack. However, the PowerPC ABI
declared that all arguments must be pushed in left-to-right order for
interop purposes, keeping the "pascal" keyword meaningless.
