I fully agree that those two are the only really useful alignment  
properties for fields in a struct.
Another thing that is needed is specifying the alignment of the struct  
itself, for example if it contains fields that one wants to use with  
SSE.
So one should have the freedom to specify the wanted alignment for the  
structure
