This is a bug report for perl from david.dyck@fluke.com,
generated with the help of perlbug 1.34 running under perl v5.9.0.

[Please enter your report here]

Recent bleading edge version have started causing
Regexp::Common to start issuing warnings that they
didn't before.

$ perl -we 'use Regexp::Common'
Variable "$s" is not available at (re_eval 47) line 1.
Variable "$x" is not available at (re_eval 47) line 1.

Does this indicate a bug in perl or in Regexp::Common?
(the error message makes it a bit difficult to
 identify the offending line(s) of code.

make test with Regexp-Common-2.113 passes all test, but
it too issues many warnings during the tests.

It looks like the warning is comming from
    Regexp-Common-2.113/lib/Regexp/Common/comment.pm

in code like:

	sub {
            use re 'eval';
            my ($s, $x);
            my $re = qr {\b([A-Za-z]+)\b
                         (?(?{($s, $x) = (0, lc $^N);
                              $s += $Regexp::Common::comment::scores
                                    [ord (chop $x) - ord ('a')] while length $x;
                              $s  >= 5 && $s < 18})XXX|)}x;
            $re;
        };
