Bash 4.3.30 on AIX 6.1 filename completion

[Steve Dahl]

If on AIX 6.1, I mount an NFS volume exported from CentOS 6.7, Bash 
(4.3.30) is unable to do tab completion within that file system. If (for 
example) I search for files that I know exist, such as:

    ls -l /path/to/files/*.h

...no answers are returned even though

    ls -l /path/to/files

...will show those files.

In the course of trying to understand why AIX didn't like our new NFS 
server, I found that bash's glob.c depends on opendir(), and that in a 
simple test on that NFS file system, opendir() fails with EOVERFLOW.

The AIX man page for opendir() documents opendir64() but doesn't go into 
a lot of detail about what it's for other than the inferred hint that it 
might allow for file sizes larger than 4 GB.

The same simple test that gets EOVERFLOW when I use opendir() indeed 
seems to succeed when I use opendir64(). Once you know the answer, you 
can find hints on IBM forums that seem to confirm it.

Is there already a version of "bash" somewhere that already supports 
large file systems on AIX if its compilation is configured right?
