HI,

I was wondering whether anyone had figured out a way to either guarantee alignment or capture misalignment in the case where structures are contained within other structures.  For example, 

      struct foo {
          struct p1 foo1;
          struct p2 foo2;
          struct p3 foo3;
      };


Is there anyway to make sure that the structure foo2 starts on a longword boundary?  Right now we're just making sure that the person responsible for defining each one of the structures makes sure that the size of their structure is a multiple of 4.  Is there any easier way?  We want to be able to detect the misalignment in case someone messes up unintentionally.
