I've no choice to move away from Windows. If I'm able to make a fix, in which 
format do you like to get it. UNIX style patch?

As far as I can see, it is only util.c that did not compile. The other approach 
available is to port diffutils to Visual Studio 2015 (we already have it 
working for Visual Studio 2013).
Everything else need to move to Visual Studio 2015, so diff also need to move 
(otherwise end-users are forced to install different versions of the visual 
studio runtime).

And I even think that the build issues are related to something that was just 
introduced with diffutils 3.5... But I will check.

Kees
