By my opinion -fipa-struct-reorg GCC option could break structure.
That option would probably break a lot of things. Like our "variable-sized array as last field of a struct" hacks.
And maybe there are more compiler magic switches and optimization on different platforms which can modify structure alignment or member order. It probably does not happen often but footprint should protect people to shot himself.
We depend on a certain member order and alignment rules. If we're worried about that, we should add checks in configure instead, to barf if you try to use such options.
