introduced bits/byte. For this naming the address unit is per

definition a byte. If bits/byte is not explicitly set, 8 is assumed.
>address works now with bits/byte and translates between target
address units and the hosts' one.
Attention:
In this state this will never work with host address unit size different
than 8 bits.
Step up translation (from 8 to 16 bits address unit size) will only work
with enormous care because "chars" in cross behaves not like "chars" in the
target. Any pre-calculation of offsets that is compiled in litarally
will fail!
Better solution: Emulate target address-unit size in cross, ugh!
