Summary: upack fails under certain conditions on Windows

Initial Comment:
When using unpack to decode and swap byte orders for 
a binary file that consists of a series of unsigned 
integers (big-endian 32bit format)  on a Windows 2000 
& XP machine,  a false result is returned for certain 
values.  The script failed reading the first value with the 
number 26 in big-endian format ('\x00\x00\x00\x1a') 
The same script and datafile worked fine using cygwin's 
version of python on the same machines, and also 
worked correctly on a Linux machine.  The attached files 
should be able to reproduce the behavior.

This is not a bug.  To read binary files on Windows, you
must open them with mode 'rb'.
