  67  * This order has the ranlib structures in the order the objects appear in the
  68  * archive and the symbol names of those objects in the order of symbol table.
  69  * The second know order is sorted by symbol name and is produced with the -s
  70  * option to ranlib(1).  This table of contents has the archive member name
  71  * "__.SYMDEF SORTED" and many programs (notably the 1.0 version of ld(1) can't
  72  * tell the difference between names because of the imbedded blank in the name
  73  * and works with either table of contents).  This second order is used by the
  74  * post 1.0 link editor to produce faster linking.  The original 1.0 version of
  75  * ranlib(1) gets confused when it is run on a archive with the second type of
  76  * table of contents because it and ar(1) which it uses use different ways to
  77  * determined the member name (ar(1) treats all blanks in the name as
  78  * significant and ranlib(1) only checks for the first one).
