Tom Moran says
<<Discriminants are commonly placed in a record pretty much like any
other component, and you should be able to use record rep clauses to
force different compilers to all do what you want. Tags are (in my
experience) 32 bits on the front and not movable. If the hardware
gadget wants the data, but not the tag, how about
>>
This is wrong, tags are typically pointers, so they are only 32-bits on
32-bit machines. GNAT on the Alpha, or on the MIPS in n64 mode will
allocate 64-bits for the tag.
