    void foo() __attribute__ ((stdcall));

This means that the called function cleans the stack, not the caller.
But I think it does not reverse the order of arguments.  See also node
"Function Attributes" of gcc.info.

Like GNU C.  Caller cleans the stack.  Can be changed with

    Procedure Foo; attribute ( stdcall );

(* I personally find those double parentheses very funny.  Has anybody
an idea why they are doubled? :*)

Hope this helps,
