When calling winreg.SetValueEx(key, value_name, reserved, type, value), the value argument does not support the full range of a 32 bit unsigned integer, which the Window's registry API is expecting. For example, passing a value 0x80000000 will result in the following exception:
OverflowError: Python int too large to convert to C long. For consistency with the Window's binding, it should support an unsigned long.

Brian - I think this is your area

Likewise, the winreg.QueryValueEx method returns a signed 32 bit value, instead of a 32 bit unsigned value.

Here is a patch for the first part (SetValueEx).

New changeset b9752b6c40f8 by Brian Curtin in branch '3.2':
Fix #14420. Use PyLong_AsUnsignedLong to support the full range of DWORD.

This is fixed on 3.2 through 3.4. On 2.7 we get a ValueError trying to do the same thing so I'll create a separate issue for that since it involves fixing more than just the change in Py2Reg.

New changeset ccbb16719540 by Brian Curtin in branch '2.7':
Fix #14420. Check for PyLong as well as PyInt when converting in Py2Reg.

Never mind msg178303. The fix was roughly the same and in the same area, so now we're covered on 2.7 as well.
