+   Using the following chars caused a compiler warning on HIUX (so I replaced

+/* 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.  */
