Subject: Rep spec for tagged type

I'm trying to create a rep spec for a tagged type and getting errors
from GNAT that say `compoonent overlaps tag field of ...'.
I gather this means that GNAT stores the tag for the type at the
beginning of the memory used for the type and I'm trying to overwrite
that by starting my rep spec at 0.
So, I figure I need to shift my rep spec along by however big the tag
is. How can I find the size of this? (I'd rather do it properly that
assume it's 32 bits on my machine).
Thanks,
Dan.
