And given the aliased rule, which works fine with the wrapper type but 
not with discriminated component, I think GNAT's behavior is as it 
should be.  It is just that to the exent that this behavior is changed 
from Ada 83, I would have expected it to be documented as such.  The 
rule for aliased components may be a change from Ada 83, but the 
presence of aliased is all the documentation needed for that.  But the 
rule for unaliased components may have implicitly changed here. Again it 
might be considered an extention, not a change, and as such not needed 
documentation.
