  17 /* The Symdef member of an archive contains two things:
  18    a table that maps symbol-string offsets to file offsets,
  19    and a symbol-string table.  All the symbol names are
  20    run together (each with trailing null) in the symbol-string
  21    table.  There is a single longword bytecount on the front
  22    of each of these tables.  Thus if we have two symbols,
  23    "foo" and "_bar", that are in archive members at offsets
  24    200 and 900, it would look like this:
  25         16              ; byte count of index table
  26         0               ; offset of "foo" in string table
  27         200             ; offset of foo-module in file
  28         4               ; offset of "bar" in string table
  29         900             ; offset of bar-module in file
  30         9               ; byte count of string table
  31         "foo\0_bar\0"   ; string table  */

  33 /* Format of __.SYMDEF:
  34    First, a longword containing the size of the 'symdef' data that follows.
  35    Second, zero or more 'symdef' structures.
  36    Third, a longword containing the length of symbol name strings.
  37    Fourth, zero or more symbol name strings (each followed by a null).  */
