Bear in mind that making the entire structure 'packed' means gcc treats it as being potentially completely unaligned (ie attribute 'packed' means 'packed and not at all aligned', not just 'packed'). This isn't a big deal except for structs where we care about atomicity, though, which I don't think is the case here. -- PMM
