Hi
I'm running python on OpenBSD/sparc64 (SUN Ultra 10) and have question about struct module.
On this machine struct.pack() gives me:
struct.pack('l', 1) '\x00\x00\x00\x00\x00\x00\x00\x01' struct.pack('i', 1) '\x00\x00\x00\x01'
On i386 box I have:
struct.pack('l', 1) '\x01\x00\x00\x00' struct.pack('i', 1) '\x01\x00\x00\x00'
Because of this, OpenBSD port have following patch: OpenBSD:patch−Libtesttestfcntlpy,v1.1.1.12003/12/3117:38:33sturmExpOpenBSD: patch-Lib_test_test_fcntl_py,v 1.1.1.1 2003/12/31 17:38:33 sturm Exp OpenBSD:patch−Libtesttestfcntlpy,v1.1.1.12003/12/3117:38:33sturmExp --- Lib/test/test_fcntl.py.orig 2003-12-31 12:13:00.000000000 +0100 +++ Lib/test/test_fcntl.py 2003-12-31 12:14:14.000000000 +0100 @@ -22,9 +22,13 @@ if sys.platform.startswith('atheos'):

Is it OK? It should work like this on 64bit machine, right?
Thanks,
Alek
