1 /* BFD back-end for IBM RS/6000 "XCOFF" files.

3 FIXME: Can someone provide a transliteration of this name into ASCII?
4 Using the following chars caused a compiler warning on HIUX (so I replaced
5 them with octal escapes), and isn't useful without an understanding of what
6 character set it is.
