Hi

I have dowloaded the latest release 3.5 in order to generate a win64 
version.

I had to apply the following patch in order to be able to compile 
successfully

I am aware that my problem may be arised from my patch but I don't think so.

The configure command I used was

./configure --host=x86_64-w64-mingw32 --prefix=/tmp/diffutils-3.5-mingw64

diff.exe was generated and executes.  My problem is that it does not 
produce any differences when it should.

Here is the output difference between  the version 3.5 I produced and a 
version 2.7 I found on the net
