Summary: unpack produces incorrect result in certain circumstances 

Initial Comment:
When reading a binary datafile that consists of a series 
of unsigned integers (32 bit) in big-endian format and 
using unpack to read and convert the data to little 
endian, long unsigned integers, errors were noted on 
both Windows 2000 and Windows XP.  The data file 
(attached) produced errors on both Windows platforms 
when trying to read '26' in big-endian format, but the 
same operation would work on the command line.  The 
same script and datafile were used on the same 
machines using cygwin, (and the same version of 
Python: 2.3.3) and the results were correct.  The script 
and datafile also produced expected results on a Linux 
box.  The script and datafile that can reproduce the 
results are attached in a zip file.
