From `perldoc -f binmode', perl 5.8.4, emphasis mine
On some systems (in general, DOS and Windows-based systems) binmode() is necessary when you're not working with a text file. For the sake of portability it is a good idea to always use it when appropriate, and to never use it when it isn't appropriate. Also, people can set their I/O to be by default UTF-8 encoded Unicode, not bytes.

In other words: regardless of platform, use binmode() on binary data, like for example images.

images, executables, zipfiles, tarballs, encrypted ...

I run a Win32 PPM repository for perl 5.6.x and 5.8.x -- I take requests (README).
