Let's start with that one first, as it's likely related to fstatat.
This test is in tests/options.at.
What's the output of the following shell commands (assuming Bash),
using the newly-built 'tar'?

echo > file1
TAR_OPTIONS=--numeric-owner truss ./tar chof archive file1

Assuming Bash as the shell on AIX or HP-UX isn't a safe bet - neither one ships with that shell even as an optional install.  IBM does include a (very old) .rpm of bash 3.2 compiled for AIX 5.2 in their Linux Toolkit (which itself hasn't been updated in forever), and it would probably run, but we prefer to use more current OS-native compiles for our toolkit(s).

So - that said - using /bin/ksh ... 

$ echo > file 1
