The "Field cannot be resolved" checker does not like this code:

   iov_t send_mx [1];
   SETIOV (send_mx, 0, 0);

I have replaced the second and third argument with zeroes for this example.  The checker does not like "send_mx" as 
written.  It is happy if I change it to "send_mx + 0" or "&send_mx [0]".  As written, it complains with this error 
description:

Field 'SETIOV (send_mx, 0, 0)' could not be resolved

I believe this is a bug because send_mx represents the address of the array.
