test_winreg fails with:
ERROR: testLocalMachineRegistryWorks (test.test_winreg.WinregTests)
Traceback (most recent call last):
  File "C:\Projects\python-trunk\lib\test\", line 86, in
    with OpenKey(key, "sub_key") as sub_key:
AttributeError: __exit__


_winreg.OpenKey() returns a PyHKEY.  This type can no longer be used in
a "with" statement after r72912 introduced the SETUP_WITH opcode.  The
old way used PyObject_GetAttr() to get __enter__ and __exit__ which
works fine with PyHKEY since it has a tp_getattr function.  The new way
uses _PyObject_LookupSpecial() which uses the MRO and the dict of the

I guess the right fix here is to update PyHKEY so it uses the modern
APIs but I don't know how to do this without breaking the special casing
for the "handle" member.  Using T_INT isn't quite correct since it is a
pointer not an int.

Fixed with r73325.
2.7 really introduces an incompatibility here; I added an entry in the 
whatsnew file.
