I am indeed passing this to some C code, and I realize that what I am doing
is cheating, just a little. The reason is I can't seem to get the stuff to
the C function by value, if I pass it by reference its happy, but it barfs
when I try to do it by value.
My old trick of translating pointers into Ada types by creating a function
to return the record by value also doesn't work...

Thanks, it does indeed eliminate the error, but it leaves me with a bad
taste. Somewhat like resorting to an unchecked_conversion.
Is there a "proper" way to do this, or am I stuck with the unchecked
solution?
