  Revision 1.93  1999-09-15 20:24:56  daniel
  + Dw switch now does something.

  Revision 1.92  1999/09/07 15:02:41  pierre
   * powerpc default was alpha !!

  Revision 1.91  1999/08/16 15:35:29  pierre
    * fix for DLL relocation problems
    * external bss vars had wrong stabs for pecoff
    + -WB11000000 to specify default image base, allows to
      load several DLLs with debugging info included
      (relocatable DLL are stripped because the relocation
       of the .Stab section is misplaced by ldw)

  Revision 1.90  1999/08/04 13:03:11  jonas
    * all tokens now start with an underscore
    * PowerPC compiles!!
