When we put that wording into the GNU coding standards many years ago, traditional C libraries were more important than 64-bit MS-Windows, and the reality was that one cannot easily write code that works with both 64-bit MS-Windows and traditional C libraries that lack support for formats like %td. Although 64-bit MS-Windows is obviously more important now than it used to be in the good old IA-64 days, it's not obvious that we can jettison support for traditional C environments quite just yet.

Perhaps it wouldn't be to hard to change diffutils to be portable to nonstandard platforms like MS-Windows, while still maintaining portability to traditional C. The proposed patch won't suffice for that, though.
