I should have done this earlier, sorry. A quick test on Windows XP,
using the released Python 3.0 installer and a hacked regrtest.bat
(which is basically regrtest.sh converted to Windows bat file syntax)
gives:
>regrtest.bat \Apps\Python30\python.exe
Traceback (most recent call last):
File "_importlib.py", line 836, in _import_module
loader = self._search_meta_path(name, path)
File "_importlib.py", line 751, in _search_meta_path
raise ImportError("No module named %s" % name)
ImportError: No module named test
During handling of the above exception, another exception occurred:
Traceback (most recent call last):

return self.default_path_hook(path_entry)

File "_importlib.py", line 112, in _path_absolute
return _os._getfullpathname(path)
WindowsError: [Error 2] The system cannot find the file specified: ''
Looks like ntpath._getfullpathname doesn't like an empty string as an
argument. The following patch seems to fix this:
--- _importlib.py.orig 2009-01-03 19:50:22.121422900 +0000

def _path_absolute(path):
"""Replacement for os.path.abspath."""
try:

+ return _os._getfullpathname(_os._getcwd())
return _os._getfullpathname(path)
except AttributeError:
if path.startswith('/'):
I then get the following output:
