     other places expect they can calculate addresses by adding it
     and such, meaning it must be in units of target bytes.  For
     some DSP targets, in which HOST_CHAR_BIT will (presumably) be 8
     and TARGET_CHAR_BIT will be (say) 32, this is a problem.

     One fix would be to make this field in bits (requiring that it
     always be a multiple of HOST_CHAR_BIT and TARGET_CHAR_BIT) ---
     the other choice would be to make it consistently in units of
     HOST_CHAR_BIT.  However, this would still fail to address
