In article <292@foxvax5.UUCP> dbr@foxvax5.UUCP (D.B. Robinson
(Douglas)) asks how System V handles cyclic dependencies if it has
no ranlib command.  As I understand it, the System V `ar' has a
`virtual ranlib' built in to it; running `ar' on an object file
(one with an appropriate magic number) automatically builds or
updates the __.SYMDEF archive member.  It seems to me that this
is the correct external behaviour: the library builder should
manage its table of contents itself.  (I would be just as happy
with a /usr/bin/ar shell script that invoked ranlib when inserting
an object file, although it would probably be slower.)
