Summary: Interactive window does not return printf properly

Initial Comment:
In a nutshell, when i use PythonWin to run a simple function using ctypes on Windows Vista 64-bit (Python 2.5.4 is 32-bit) i wasn't seeing the expected output but when i ran the same function using the Windows command prompt it was alright

re-pro steps:
----------------------
1. Start PythonWin interactively (This is present after a successful installation of Python 2.5.4)
2. Key the following into the interactive window
>>> from ctypes import *
>>> cdll.msvcrt.printf(c_char_p('hello world'))

expected results:
--------------------------
the string 'hello world11' 

actual results:
----------------------
the string '11' (The 'hello world' appears to be gobbled)

additional info:
-----------------------
When i ran the same sequence as described in the re-pro using a normal Win32 command prompt and starting python interactively like that, i got what i expected.

Message:
Thanks for the report - but there is very little I can do here - pythonwin
overrides Python's sys.stdout etc, but overriding the C runtime concept of
stdout/stderr is far harder and beyond what pythonwin tries to do.
