I don't think you can do this on System V Release 3.

You CAN do this on System V Release 3.
From the UNIX System V Release 3 Programmer's Reference Manual, LINT(1),

          The following options are used to suppress certain kinds of
	  complaints:

          -u   Suppress complaints about functions and external
               variables used and not defined, or defined and not
               used.  (This option is suitable for running lint on a
               subset of files of a larger program).

          -x   Do not report variables referred to by external
               declarations but never used.
