   FIXME: Can someone provide a transliteration of this name into ASCII?

   character set it is.

/* XCOFF archive support.  The original version of this code was by
   Damon A. Permezel.  It was enhanced to permit cross support, and
   writing archive files, by Ian Lance Taylor, Cygnus Support.

   XCOFF uses its own archive format.  Everything is hooked together
   with file offset links, so it is possible to rapidly update an
   archive in place.  Of course, we don't do that.  An XCOFF archive
   has a real file header, not just an ARMAG string.  The structure of
   the file header and of each archive header appear below.

   An XCOFF archive also has a member table, which is a list of
   elements in the archive (you can get that by looking through the
   linked list, but you have to read a lot more of the file).  The
   member table has a normal archive header with an empty name.  It is
   normally (and perhaps must be) the second to last entry in the
   archive.  The member table data is almost printable ASCII.  It
   starts with a 12 character decimal string which is the number of
   entries in the table.  For each entry it has a 12 character decimal
   string which is the offset in the archive of that member.  These
   entries are followed by a series of null terminated strings which
   are the member names for each entry.

   Finally, an XCOFF archive has a global symbol table, which is what
   we call the armap.  The global symbol table has a normal archive
   header with an empty name.  It is normally (and perhaps must be)
   the last entry in the archive.  The contents start with a four byte
   binary number which is the number of entries.  This is followed by
   a that many four byte binary numbers; each is the file offset of an
   entry in the archive.  These numbers are followed by a series of
   null terminated strings, which are symbol names.  */
