/* If you are adding a U8 or U16, check to see if there are 'Space' comments
* above on where there are gaps which currently will be structure padding. */
/* Within a stable branch, new variables must be added to the very end, before
* this comment, for binary compatibility (the offsets of the old members must
* not change).
* (Don't forget to add your variable also to perl_clone()!)
* XSUB.h provides wrapper functions via perlapi.h that make this
* irrelevant, but not all code may be expected to #include XSUB.h.
