I need to clarify this.  The du.exe that is being counted
in each of these instances is the 4.0 version that I built
straight from the fileutile-4.0 gnu source.

the 443705 is the value returned from doing a 'du -b'
using the 3.16 due command COUNTING the du.exe 4.0 binary

the 222208 is the value returned from doing a 'du -b'
using the 4.0 binary to count itself.

the 444416 is the value returned from doing a 'du -b'
using the 4.0-3 binary to count the bytes of the 4.0 binary.

Three different versions of du counting the same du.exe
giving three different results.  I know that 4.0 had a 
problem - hence the use of 4.03, but I'm still confused about the
difference in results between the 3.16 binary and the 4.0-3
binary counting the same file.
