/* 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  */
