This is a long overdue change so we don't break ADL of operator|.
I think will not break source or binary compatibility.
The problem is code like this:
namespace Foo {
struct MyStruct;
MyStruct operator|(MyStruct, MyStruct);
void someFunction() {
fooLabel->setAlignement(Qt::AlignLeft | Qt::AlignTop)
}
}
This would be an error before as ADL would find only the Foo::operator| and not
the global one since the arguments are not in the global namespace.
After this change, ADL works fine and this code compiles
This bites people with misterious error, see questions on

[ChangeLog][QtCore] QFlags's operator| for enum types in the Qt namespace are
now declared in the Qt namespace itself.

README
This directory contains autotests and benchmarks based on Qt Test. In order
to run the autotests reliably, you need to configure a desktop to match the
test environment that these tests are written for.
Linux X11:
* The user must be logged in to an active desktop; you can't run the
autotests without a valid DISPLAY that allows X11 connections.
* The tests are run against a KDE3 or KDE4 desktop.
* Window manager uses "click to focus", and not "focus follows mouse". Many
tests move the mouse cursor around and expect this to not affect focus
and activation.
* Disable "click to activate", i.e., when a window is opened, the window
manager should automatically activate it (give it input focus) and not
wait for the user to click the window.
