mc dropped path when try open NFS mount point from Windows 2012

[dnskmv]

Hello all.

We found bug when on AIX host I try open mount point of NFS server based on Windows 2012.

Configuration:
Windows 2012 Server - as NFS server
AIX 6.1, 7.1 - as NFS Client

mount point - /mnt/tmp
proto: NFSv3

Problem:
When we move to the mount point in MC (/mnt/tmp) we see the contents of NFS Share from the server. Going to any directory below - throws us into the root (/)
Any ideas how we can fix this?

In shell this problem not repeated.
From test linux client with mc (4.8.7) problem not repeated.

We did some fixing in #3987 . If you can still reproduce it with current mc and provide us with some way to diagnose the problem, please reopen.
