This looks like a prototype mismatch with the aio_suspend() library

What is the prototype of this function on your system? The prototype
is the same on several systems that I have checked (RHEL4, Debian
somethingorother with kernel 2.6.18, OS X Leopard):

      #include <aio.h>

      aio_suspend(const struct aiocb *const list[], int nent,
          const struct timespec *timeout);

Is it different on your system?

FWIW, I notice that in the upgraded ROMIO in the just-released OMPI
v1.3, it doesn't use the call to aio_complete at all. So you might
want to try that...?
