Summary: socket.inet_aton on 64bit platform

Initial Comment:
Hi,

socket.inet_aton() returns an 8 byte string when built 
on Linux/IA64. This should be 4 bytes on all 
architectures. Example:

>>> import socket
>>> socket.inet_aton('192.168.2.1')
'\xc0\xa8\x02\x01\x00\x00\x00\x00'

The bug is caused by Modules/socketmodule.c using 
sizeof(unsinged long) when constructing the string, 
which is 8 bytes on Linux/IA64.

The bug seems to be fixed in Python 2.3 in the case 
struct in_addr is available. Otherwise it still uses an 
unsigned long.

Geert

I've just run into this problem, which is still present in
current cvs.   This now (2.3.x and cvs head) occurs for the
code path where inet_aton is not detected by configure, so
it's not a terribly common case. Of course, I have one ...
The conversion needs to be done on a 32-bit quantity.  It's
a one-liner to fix, I'll submit a patch if I can make the
patch manager work for me.
