If you use {$A+} all fields should appear to aligned to 8 byte boundaries
(The default).
I think would be easier to make it controllable, to use packed record and
add some "Foo Bar" padding variables if needed.
If the original structure is continuous then packed record with correct
field sizes should be used. it there are gaps in original still i would use
packed record and add padding into the gaps.
Anyhow very nice to see this kind of effort going on!
