19/* The Symdef member of an archive contains two things:
20   a table that maps symbol-string offsets to file offsets,
21   and a symbol-string table.  All the symbol names are
22   run together (each with trailing null) in the symbol-string
23   table.  There is a single longword bytecount on the front
24   of each of these tables.  Thus if we have two symbols,
25   "foo" and "_bar", that are in archive members at offsets
26   200 and 900, it would look like this:
27        16              ; byte count of index table
28        0               ; offset of "foo" in string table
29        200             ; offset of foo-module in file
30        4               ; offset of "bar" in string table
31        900             ; offset of bar-module in file
32        9               ; byte count of string table
33        "foo\0_bar\0"   ; string table  */
