Try this (untested !):

#!/usr/bin/perl

          opendir DIR,"$ARGV[0]";
 	  my @allfiles=readdir(DIR);
          closedir DIR;

          foreach my $file (@allfiles) {
 	   if (-f "$ARGV[0]/$file") {
            my $file_lower=toLOWER_uni($file);
            if (defined $hash{$file_lower}) {
             unless ($hash{$file_lower} eq "") {
              print $hash{$file_lower}."\n";
              $hash{$file_lower}="";
             }
             print $file."\n";
            }
            else {
             $hash{$file_lower}=$file;
            }
           }
          }
