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.

/* 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.
AIX 4.3 introduced a new archive format which can handle larger
files and also 32- and 64-bit objects in the same archive. The
things said above remain true except that there is now more than
one global symbol table. The one is used to index 32-bit objects,
the other for 64-bit objects.
The new archives (recognizable by the new ARMAG string) has larger
field lengths so that we cannot really share any code. Also we have
to take care that we are not generating the new form of archives
on AIX 4.2 or earlier systems. */

have the same length. */
