 * There are two known orders of table of contents for archives.  The first is
 * the order ranlib(1) originally produced and still produces without any
 * options.  This table of contents has the archive member name "__.SYMDEF"
 * This order has the ranlib structures in the order the objects appear in the
 * archive and the symbol names of those objects in the order of symbol table.
 * The second know order is sorted by symbol name and is produced with the -s
 * option to ranlib(1).  This table of contents has the archive member name
 * "__.SYMDEF SORTED" and many programs (notably the 1.0 version of ld(1) can't
 * tell the difference between names because of the imbedded blank in the name
 * and works with either table of contents).  This second order is used by the
 * post 1.0 link editor to produce faster linking.  The original 1.0 version of
 * ranlib(1) gets confused when it is run on a archive with the second type of
 * table of contents because it and ar(1) which it uses use different ways to
 * determined the member name (ar(1) treats all blanks in the name as
 * significant and ranlib(1) only checks for the first one).
