Summary: cannot import extension module with Purify

Initial Comment:
When run with Purify, Python cannot load any extension
module.

Here is a typical output:

Starting Purify'd application...
Python 2.4.2 (#46, Jan  3 2006, 16:05:11) [MSC v.1200
32 bit (Intel)] on win32
Type "help", "copyright", "credits" or "license" for
more information.
>>> import socket
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
  File "c:\python\lib\socket.py", line 45, in ?
    import _socket
ImportError: Module use of
python24__d$Purify_c_python.dll conflicts with this
version of Python.

It reproduces with python 2.4.2 and 2.5a0.
It works with python 2.3.3.

The pb seems to be in dynload_win.c, line 136:
while (*pch && pch[0] != '_' && pch[1] != 'd' && pch[2] !=
'.') {

This means that if a .pyd has "python_something.dll" in its
import table, it will be taken as THE python DLL.
I think the line should be:

while (*pch && (pch[0] != '_' || pch[1] != 'd' || pch[2] !=
'.')) {
