  Fixes the last problem mentioned in issue1202.

Issue #1202: zipfile module would cause a struct.error when attempting to store
files with a CRC32 > 2**31-1.  (on trunk this was merely a warning, in the py3k
branch this caused an exception so I'm treating this as a release blocker and
merging it now)
