Where do you need help with this? Have you looked at Text::Diff for example. Do you intend a traditional diff type text output, or is the real effort going into some sort of side by side GUI view of the diffs?

Comparing *nix and Windows files need not be a big issue. Just massage the line ends to be compatible before you diff, or use a diff that is insensitive to such things.

Note that there are many GUI diff tools available already - why do you need to reinvent this particular wheel?

Perl is Huffman encoded by design.
