 11.2.1 Updating Archive Symbol Directories
 ------------------------------------------
 
 An archive file that is used as a library usually contains a special
 member named `__.SYMDEF' that contains a directory of the external
 symbol names defined by all the other members.  After you update any
 other members, you need to update `__.SYMDEF' so that it will summarize
 the other members properly.  This is done by running the `ranlib'
 program:
 
      ranlib ARCHIVEFILE
 
    Normally you would put this command in the rule for the archive file,
 and make all the members of the archive file prerequisites of that rule.
 For example,
 
      libfoo.a: libfoo.a(x.o) libfoo.a(y.o) ...
              ranlib libfoo.a
 
 The effect of this is to update archive members `x.o', `y.o', etc., and
 then update the symbol directory member `__.SYMDEF' by running
 `ranlib'.  The rules for updating the members are not shown here; most
 likely you can omit them and use the implicit rule which copies files
 into the archive, as described in the preceding section.
 
    This is not necessary when using the GNU `ar' program, which updates
 the `__.SYMDEF' member automatically.
