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.
