This hints the ABI problem exists at syscall level only.  Is that
correct?  So we can have

	preadv(fd, vec, vlen, off)

argument ordering at app <-> glibc level and

	preadv(fd, vec, off, vlen)

ordering at glibc <-> kernel (aka syscall) level and it works fine for
ARM + MIPS + PARISC?

thanks,
  Gerd
