Changes since version 2.1

* The `bfd' library has been updated to reduce a.out-format string
  table size.  The effect of this is that files linked from many input
  files with duplicate symbols (`-g' debugging records, or identical
  static symbols) should be much smaller.

Changes since version 2.0

* The ld -ySYMBOL flag (to trace references to SYMBOL) is now implemented.

* There is now support for writing ECOFF files, so ld and the
  other utilities should work on Risc/Ultrix and Irix.
