This has nothing to do with the underlying byte-endianness as the OP
needs but to do with record representation clauses mean.

It's this sort of thing that really puts me off using record reps - I
usually
just use a toolkit of generic routines that I instantiate for each type and
build to.from arrays of Unsigned_32.

You could write your own functions to do this - it is trivial, esp if you
are dealing with the predefined type Unsigned_32. Or pragma Import
the 'C' routines (yuck!).
