Summary: time.altzone does not include DST offset on Cygwin

Initial Comment:
On Cygwin (python-2.4.1-1) time.altzone is always set
equal to time.timezone.

Steps to reproduce:
$ python -c 'import time; time.tzset(); \
  print time.ctime(), time.daylight, \
  time.timezone, time.altzone'

Actual result (for CEST):
Sun May 14 13:46:55 2006 1 -3600 -3600

Expected result:
Sun May 14 13:46:55 2006 1 -3600 -7200

This causes failure of time conversions in e.g.
rdiff-backup-1.1.5

The attached patch should fix this for most timezones.
The function already uses the same heuristics in the
(!__CYGWIN__ &&  !HAVE_STRUCT_TM_TM_ZONE) case.
