It is not me who suggests using of __le16 fields inside "packed" structures, and it's that usage that demands putting of "unaligned" attribute into the type. This demand just can't be satisfied in C. If somebody ever comes up with a sane way to have [mis]alignment information in the type, then I'll probably reconsider my position, even though I do currently think that "unaligned" doesn't belong to the type. For now, my point is that one shouldn't use "packed" in the first place, and then the alignment problem just vanishes, as there is no demand to have "unaligned" in the type in this case. It's easier not to create the problem than to solve it ;) -- Sergei. ------------------------------------------------------------------------- Using Tomcat but need to do more?
