Well GNAT has always packed tightly in response to the pragma,
so we did not have to worry about this effect. We have a lot of
legacy Ada 83 customers who either want to maintain Ada 83
conmpatibility, or are allergic to changing their code, which
is why we choose to pack always. Obviously at this stage we
could not consider changing, because we have so many users
depending on the tight packing.
I suppose a configuration pragma saying you want tight packing
or not is a possibility.
