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