ftw() and AustinDraft

[Thorsten Kukuk <kukuk at suse dot de>]

Hi,

The AustinDraft writes, that ftw should not return (-1) on 
EACCESS errors.

But there are 2 exceptions which we do ignore in the moment:

1. If one component of the "path" is not searchable for the user,
   we should return -1.
2. If the file has no read permissions for the user, we should
   return -1.

I have a small patch for this which works with all of my test cases
(LSB.os test suite). But I'm not sure if it is really correct, there
are to much other cases which I could break.

  Thorsten
