coreutils df on OSX reports wrong sizes for large filesystems |

Hello,
I am running gentoo-prefix on OSX which builds coreutils. When I
compare the output of the system df to the standard GNU df I get:
$ /bin/df -h /data/hirise06
Filesystem Size Used Avail Capacity Mounted on
hiserve2:/vol/hirise06 7.9Ti 430Gi 7.5Ti 6% /data/hirise06
$ df -h /data/hirise06
Filesystem Size Used Avail Use% Mounted on
hiserve2:/vol/hirise06
2.0T 431G -523G - /data/hirise06
The 2.0T size looks suspicious to me. Maybe an integer is overflowing somewhere?
I'll also note that this was reported some time ago to the macports
bug tracking software (https://trac.macports.org/ticket/16480) but
their resolution was requesting an upstream fix.
Thanks,
-Tim

Cool, as I initially suspected, defining _DARWIN_USE_64_BIT_INODE
at the appropriate place fixes things. This has been in place
since coreutils 8.13. I verified 8.14 works on your system.

Notes:
Newer coreutils also fixed up the alignment
coreutils diverges from POSIX and defaults to 1024 byte blocks
The system df displays /net and /home even without -a. bug?
The system df displays the capacity as 100%. bug?
cheers,
Pádraig.
