I have a script which was written, and works as expected, in ActivePerl. It has been tested on a UNIX machine and works fine on there also. However, it does not work on another user's computer who uses Cygwin rather than ActivePerl. The part of the script that does not work as expected is as follows:

sub match_randomized_lists
{
    $count = 0;
    open (RANDOMIZED_LIST, $randomized_list) || die print "Script cann
+ot open $randomized_list";
    my @randomized_list = <RANDOMIZED_LIST>;
    print $randomized_list;
    print "\n";
    print @randomized_list;
    print "\n";

    foreach my $list_to_match (@array_of_lists_to_match)
    {
    $count = $count + 1;
    print OUTPUT "NUMBER ";
    print OUTPUT $count;
    $match_count = 0;
    
    foreach my $randomized_entry (@randomized_list)
    {
        chomp $randomized_entry;
    
        if ($list_to_match =~ /$randomized_entry/)
        {

        $match_count = $match_count + 1;
        }
    }
    
    print OUTPUT ": ";
    print OUTPUT $match_count;
    print OUTPUT "\n\n";   
    }
}

The code is intended to match each element of the array of randomized entries with the lists of entries in the "array of lists to match". If there is a match, the match counter increases by 1.

This way for each randomized list, I get a total number of matches with each list of entries. This is printed to an output file and further calculations are carried out on these at a later stage.

In ActiveState and UNIX, the subroutine works as expected, finding matches. In Cygwin, it never finds any matches.
Before I resort to installing Cygwin on my own computer, is/are there any known issues with anything in my code and Cygwin?
