The current git HEAD fails to compile pyside with the following error if
-DAVOID_PROTECTED_HACK=TRUE is given to cmake for building shiboken:

/home/andkit/vcs/python/pyside/pyside/build/PySide/QtCore/PySide/QtCore/qabstracteventdispatcher_wrapper.cpp:
In function ‘PyObject*
Sbk_QAbstractEventDispatcherFunc_registerTimer(PyObject*, PyObject*)’:
/home/andkit/vcs/python/pyside/pyside/build/PySide/QtCore/PySide/QtCore/qabstracteventdispatcher_wrapper.cpp:1000:76:
error: no matching function for call to
‘QAbstractEventDispatcherWrapper::registerTimer(int&, QObject*&)’
/home/andkit/vcs/python/pyside/pyside/build/PySide/QtCore/PySide/QtCore/qabstracteventdispatcher_wrapper.cpp:347:6:

Error 1

Since this is forced on when building shiboken on Windows, it is currently
impossible to get a current Windows build of pyside. (See also the "[PySide]
Windows GIT Head build"
thread on the mailing list, starting with this message:
http://lists.openbossa.org/pipermail/pyside/2010-November/001371.html)

Manually changing the generated code from
  int cppResult = cppSelf->registerTimer(cppArg0, cppArg1);
to
  int cppResult = cppSelf->QAbstractEventDispatcher::registerTimer(cppArg0,
cppArg1);
(as well as another instance of the same problem a little later) allows to
continue the build a bit further, but ultimately fails with:

/home/andkit/vcs/python/pyside/pyside/build/PySide/QtCore/PySide/QtCore/qbuffer_wrapper.cpp:997:85:
error: ‘class QBufferWrapper’ has no member named
‘QBufferWrapperconnectNotify_protected’

A similar error is produced during the build of the sample bindings if shiboken
is configured with -DBUILD_TESTS=TRUE
