Yes, this version is more robust, but you till have to cope with all
those #ifdef INT64_IS_BUSTED #else #endif. I guess if you want explicitly
int64 type in here for those platforms that do support it, then there is no
other way maybe. What I was thinking (for this particular struct only!) is just jave padded
int32's for every value, which will always be correct and no marginal problems.
And the accessor functions using the struct just employ int64 whatever it means.
