ok, my wording was wrong. What I really meant to say was that if I am
absolutely determined to find a solution because I have

There is one such document per ABI. These individual ABI documents are located
all over the web. E.g. the official x86-64 ABI can be found at

But a bunch of ifdefs should do the trick then, it should still be
possible to implement every possible implementation in pascal somehow.

Where else are the arguments if not on the stack? Everything I have
read so far about varargs and cdecl says they are on the stack.

Wouldn't it be possible to write a function in pascal that declares a
simple longint parameter instead of the varargs and then inside the
