That's right.
If someone can come up with a corresponding patch that would be great.
The alignment is a question of ABI convention, so I'm not sure how best
to do it, but maybe something like:
struct dummy
{
char a;
Lisp_Object b;
}
#define DUMP_RELOC_ALIGNMENT_BITS log2 (offsetof (struct dummy, b))
?
