In the above error message, 'd', 'h' and 'j' are all symlinks which were followed when copying the test repo, so these paths indeed won't match what's in the index, which makes checkout abort. Fortunately, there is a POSIX option to force cp to copy the symlinks: '-P'. Adding this flag to the cp invocation at line 117 of t2080 makes all parallel checkout tests pass on AIX. We also already use `cp -R -P` in the test suite (at t7001), and without any prereq, so I guess all platforms we are testing git at do support this flag in cp. I'll send a patch adding the flag at t2080.
