In order for vimdiff to work, you need to have where Vim can find it
(usually in your $PATH, or maybe in $VIMRUNTIME) a diff program which
understands the arguments that vimdiff will send it to find the
differences between the files. This is usually the case if you run on a
Unix-like OS, including Linux, Mac OSX, BeOS, etc. On Windows it may or
may not be the case.

See in particular ":help diff-diffexpr" and the last paragraph before
":help diff-patchexpr" (without the double quotes in both cases).
