Thanks. There's still something fishy going on,
since the truss output is acting like we are never
calling openat.
Can you please send a copy of your config.h? I want
to verify that HAVE_OPENAT and related macros are set.
config.h.gz attatched.
Also, can you please verify that gnu/openat.c is being
compiled and the result is being linked into 'tar'?
It's definately being compiled ...

So yes, it's being compiled and included.
Can you send the assembly-language output for openat.c?
Typically this can be done by compiling with -S rather
than with -c (all other options being the same).
