<PRE>os.urandom works on my 64-bit Windows 7 machine (ActiveState Python V2.7).
I think you can use the following to determine if 32/64bit:
import platform
if platform.architecture()[0] == '64bit':
#
# Do 64 bit stuff here
#
else:
#
# Do 32 bit stuff here

Does os.urandom work on Win64? We could just use that if someone would
help me with the OS detection (see lib/Crypto/Random/OSRNG/__init__.py).
