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

Although that change may be needed to get diffutils to compile, it is disabling 
a compile-time check that, if it fails, means that diffutils will probably break 
in some cases under mingw.

You'll have better luck building diffutils under Cygwin, which more compatible 
with the GNU platform. In the meantime I'll mark this bug report as a wishlist item.
