/* BFD back-end for rs6000 support

   Copyright (C) 1990, 1991 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.
