In /Lib/ctypes/test/test_values.py, three out of the five test cases are only run on Windows. There is a comment saying “This test only works when python itself is a dll/shared library”, and the tests run fine on Linux. So I propose to remove the Windows-only restriction, and rename the class from Win_ValuesTestCase to PythonValuesTestCase.

The immediate benefit for me is that I can see on Linux when I need to update one of those tests before I break a Windows builtbot :)

This test used to be completely disabled (probably by accident), and was enabled for Windows only in revision 6f63fff5c120. There was a comment <https://bugs.python.org/issue19493#msg206649> by Zach wondering if it shouldn’t be Windows-specific.
