For Windows build, I am using whatever latest Git provides rather than
downloading
individual components which might not be good, but I find it
convenient. The latest
Git (1.8.4) download on windows still provides 2.7, which is the
reason I am on older
version. However I agree that it is better to use latest version.

I have checked that for some of the other components like bison, flex,
ActiveState TCL we specify minimum version required, but not for diff.
http://www.postgresql.org/docs/devel/static/install-windows-full.html

+1, for minimum diff version as 2.8.
