  79.     qLink is usually the first field in queues, but back in the MacPlus
  80.     days, the DrvSts record needed to be expanded.  In order to do this without
  81.     breaking disk drivers that already added stuff to the end, the fields
  82.     where added to the beginning.  This was originally done in assembly language
  83.     and the record was defined to start at a negative offset, so that the qLink
  84.     field would end up at offset zero.  When the C and pascal interfaces where
  85.     made, they could not support negative record offsets, so qLink was no longer
  86.     the first field.  Universal Interfaces are auto generated and don't support
  87.     negative offsets for any language, so DrvSts in Disks.a has qLinks at a
  88.     none zero offset.  Assembly code which switches to Universal Interfaces will
  89.     need to compensate for that.
