I don't understand why should something like that be done by a

These are imported from gnulib, which has some maintainers that
worry about mingw*.  It's no extra work to use them,
since they don't affect the diffutils code proper.
   #include <dirent.h>
   #ifndef _D_EXACT_NAMLEN
   # define _D_EXACT_NAMLEN(dp) strlen ((dp)->d_name)

is sub-optimal for systems that have the d_namlen member in struct
dirent, but don't define _D_EXACT_NAMLEN.

Yes, that's right.  The code works correctly on such systems,
and nobody's bothered to implement any such minor tuning.
