If you break the alias rules, you get undefined behavior, and that's 
really always been the case.

In any case, I'm pretty sure your inpcb_hdr stuff will work alright, 
since it is not really any different that what we do with "struct 
device" (though I think we're going to have to look into addressing the 
struct device issue in the not-distant future).
