  You didn't read that letter that you were replying to very well:

  It doesn't seem from your reply that you have actually tried this.  Note
that to pass the option through to the linker from the compiler you would
need to add "-Wl," before it, but if you have a separate link stage in your
makefile that invokes the linker directly that would not be necessary.

    cheers,
