/* BFD back-end for rs6000 support
   Copyright 1990, 1991, 1993, 1995, 2000 Free Software Foundation, Inc.
   FIXME: Can someone provide a transliteration of this name into ASCII?
   Using the following chars caused a compiler warning on HIUX (so I replaced
   them with octal escapes), and isn't useful without an understanding of what
   character set it is.
