Actually, warnings produced by -w can often be viewed in the raw data returned by the HTTP server. It won't display in the browser, but is visible with GET (or is it HEAD?) or with a util such as curl or Sam Spade. These errors can reveal paths and filenames, which may or may not be a problem. I tend to use a BEGIN{} block to skip stupid errors ("$xxx used only once...") and/or carpout() to redirect the errors to a file.
