Summary: zipfile when sizeof(long) == 8

Initial Comment:
This bug also applies to Python 2.0.x and 2.1.x (most
likely every version).

When sizeof (long) == 8, like on Tru64 UNIX,
zipfile.testzip () fails due to a CRC error. The
problem is that in Lib/zipfile.py:
  crc = binascii.crc32(bytes)
converts the 32-bit binascii.crc32() return value to a
64-bit value (crc). We need to force crc to remain a
32-bit value. Attached is a patch though maybe someone
else can think of something better.
