Send warnings generated by a CGI script to the browser.

Should not be used in production code, but instead as aid in diagnosing warnings that don't get produced in off-line testing.

{
    my @warns;
    BEGIN {
        $SIG{__WARN__}= sub {
            push @warns, $_[0];
        }
    }
    END {
        if(  @warns  ) {
            print "\n<html><p>Warnings:<pre>\n",
                @warns, "</pre></p></html>\n";
        }
    }
