Possible; I'll give it a shot. At this point, it requires a full
autoreconf, so I spent some time getting coreutils.git up and running
rather than just building from the snapshot.
Now I'm seeing this with gcc 4.8.3:
CC lib/openat-die.o
lib/openat-die.c: In function 'openat_save_fail':
lib/openat-die.c:34:1: error: function might be candidate for attribute
'noreturn' [-Werror-suggest-attribute=noreturn]
openat_save_faile (int errno)
^
Looks like something to patch in gnulib. I wonder what's going on here,
since cygwin DOES have openat(), so I'm not sure why gnulib is wanting
to replace it (not like other systems where the function is lacking
altogether).

I'll try and take a look at that as well.
