I believe the entire issue was what the compiler can do in the *absence* of a
rep clause. Its pretty clear that it needs to honor any record rep clause, or
die trying. But it was suprising to some that in *absense* of a rep clause,
compilers still aren't supposed to rearrange record fields to make a size clause
attainable.
