Thanks for the hint, Jim. I have attached a (one-liner) patch which I
have tested under the follow conditions:
- AIX 5.3 with coreutils-6.12 (no previous problems, and no
regressions with patch)
- AIX 6.1 with coreutils-6.12 (would not compile without patch, does
seem to work with patch just fine)
- AIX 6.1 with coreutils-7.0 (compile test passed, did not runtime
test - no reason to believe that there will be any regressions)

Please confirm the inclusion of this patch when you get a chance.
Also, is there an ETA for >7.0 alpha release of coreutils? (So I can
know when to stop tracking this patch)

Thanks much!
