Re: Building Diffutils with MinGW

Yet another issue is with this part of src/system.h:

  #ifndef same_special_file
  # if HAVE_ST_RDEV && defined S_ISBLK && defined S_ISCHR
  #  define same_special_file(s, t) \
       (((S_ISBLK ((s)->st_mode) && S_ISBLK ((t)->st_mode)) \
	 || (S_ISCHR ((s)->st_mode) && S_ISCHR ((t)->st_mode))) \
	&& (s)->st_rdev == (t)->st_rdev)
  # else
  #  define same_special_file(s, t) 0
  # endif
  #endif

Since the configure script doesn't test for HAVE_ST_RDEV, the upshot
of this seems to be that same_special_file will always yield zero on
all platforms, which doesn't seem to be the intent.  Apologies if I
missed something important.
