append _unused to the expression defined using unused() macro

This way if variables defined using unused() macro are actually
used then code will not compile...

- removed unused usage around one argc and one argv since those
  were used

- changed one unused (char *argv[]) to unused (char **argv) to
  work with modified unused() macro definition
