I think I have the solution!
I suggest that 'aliased' was always inappropriate anyway.
When you are declaring an object which will overlay a piece of memory that
will correspond to some external entity (e.g. an address range corresponding
to a memory-mapped I/O facility, such as a memory-mapped graphics device),
you do not need (or want) 'aliased', you need to mark the object (or its
static subtype) as 'volatile'. This is done with the Volatile pragma, see
RM95 C.6.
