Summary: os.remove fails on win32 with read-only file
Initial Comment:
On Windows XP SP2 and Python 2.3.3 or 2.4 a call to
os.remove returns Errno 13 permission denied on a
read-only file. On linux, python will delete a
read-only file.

This is a platform issue; Windows associates delete privileges
with the file, Unix with the directory. I doubt it's a good idea
to "fix" Python's remove by making it incompatible with the C
library's implementation.
(on the C level, unlink() is the same thing as remove(), btw).

Yup. I can reproduce that on Win2k.
Seems posixmodule.c uses _unlink, _wunlink, which are
documented at MS as failing on readonly:
"Each of these functions returns 0 if successful. Otherwise,
the function returns 1 and sets errno to EACCES, which
means the path specifies a read-only file, or to ENOENT,
which means the file or path is not found or the path
specified a directory."
Seems others have "fixed" it by just changing the mode and
trying again:
