You don't need to. Microsoft ships GNU diff as part of an optional MS-Windows 
subsystem. This should be a lot less work for us maintainers than trying to 
maintain a separate MS-Windows "native" port (whatever "native" means) for GNU 
diff. See:

"git format-patch" format, where the commit message uses GNU ChangeLog style. 
See the existing git repository for examples of this. The changes should be 
minimal and cleanly separable from the mainline source, and using the same style 
as what we have now.
