I should have added that the Recommended Level of Support does seem to 
require supporting that (probably should have read it before pushing 
"send"!), so in that sense, it's a GNAT bug to not allow it. But 
practically, 0 and 1 are the same for a specified alignment; nothing is 
going to be different about the default allocation, so it's doesn't really 
matter.
