I am trying to test large file support (greater than 2GB) on QNX 6.4.1.  FIrst, I found that CIFS doesn't support large 
files so I couldn't copy the file over to my qnx6 target.  So I zipped up the large file and copied it over.  Then I use
 unzip to attempt to unzip the large file onto the qnx6 target.  It failed after it had extracted 2GB of the file, and 
gave this error message:

Write error (disk full?). Continue? (y/n)?

If you press ‘y’, it exits right away by reporting a CRC error.  Do these utilities support large files?  Are there 
any other utilities that will also have problems with large files?

Here is my unzip version:
# use -i /Development/unzip

The fs-cifs version:
