It doesn't get confused; it simply uses a different format for the
parameter list when functions return struct.  A dummy first entry is
added to hold the address of an instance of the appropriate struct
into which the return value is placed.  Unfortunately, the startup
code, which always calls "main" as an int function, expects argc to
be there.
