   Here is a fix I received from an RTEMS user.  This was in binutils 2.8.1
   and I am not sure whether or not it has been fixed since.

I don't understand this patch, and I would need more information.  My
m680x0 book indicates that the original value is correct, since the
set of operands permitted for the tbl instructions are very limited.

I checked in a version of this patch.  Oddly, the original source does
not appear in my sources.  Thanks for sending it.
