From: Brandon Casey <drafnel@xxxxxxxxx>
Python 2.4 lacks the following features:
subprocess.check_call
struct.pack_into
Take a cue from 460d1026 and provide an implementation of the
CalledProcessError exception. Then replace the calls to
subproccess.check_call with calls to subprocess.call that check the return
status and raise a CalledProcessError exception if necessary.
The struct.pack_into in t/9802 can be converted into a single struct.pack
call which is available in Python 2.4.
