Upload of binary files

[ben.hutchings at businesswebsoftware.com]

stdin and stdout are opened in text mode, since they are normally used
for text.  On Windows you need to switch them to binary mode if you
will read or write binary data.  I think you need to switch stdin
over before 'import cgi' as that may parse input immediately.  The
following code should do the trick:

try:
    import msvcrt, os
    msvcrt.setmode(0, os.O_BINARY) # stdin = 0
    msvcrt.setmode(1, os.O_BINARY) # stdout = 1
except ImportError:
    pass
