See my post of May 11. Yes, I know. It seems that AI12-0218 and Scalar_Storage_Order are focused = on the wrong topic (i.e., the topic of a 2nd solution to the endian byte-sw= apping). A replacement to AI12-0218 should be focused on =E2=80=A2portably= =E2=80=A2 (among all Ada compilers) choosing between the 2 alternative byte= -swapping Record Representation Clauses on different targets.
