That doesn't make much sense. The A64 doesn't have any particular
reason to behave like the R40, and the R40 can definitely use a
different compatible if it has a different behaviour. But I don't see
*why* the A64 not behaving like the R40 is a justification to remove
the A64 compatible. Especially when the R40 was released later.

Add a new compatible, and leave the A64 compatible alone.
