Here it is:

You need the gnuwin32 patch.exe in your path. Then do

   emacs -Q

Open the file the-patch.diff. Create a new buffer with C-x b. Insert the 
file file-to-patch.txt in this.

Then from the menus select Tools - Apply patch - To a Buffer ...

Choose the patch and buffer to patch from above. After this Emacs 
freezes, at least for me (CVS from 070306).
