We'd already rejected that feature since df -g
behaves differently on various platforms.

I found (your?) bug-report reply at http://lists.gnu.org/archive/html/bug-coreutils/2009-12/msg00002.html

And understand a bit of the history. Maybe AIX has df -g because of it's BSD affinity that goes back a long, long time.

AIX does have a -g option for du.

And now that I have been reading configure --help, I may just remove df/du from the coreutils I package (and figure out a way to supply them as an optional addition) using --enable-no-install-program="df,du". This will certainly resolve my problem with wanting to use df -g nad having to type /us/bin/df -g to get it when I need it. :)
