[Releasing] Qt 5 alpha 20120314: linux g++ C++11: failure in qtquick1

[Thiago Macieira]

Error:
src/declarative/qml/qdeclarativecompiler.cpp:445:51: error: narrowing 
conversion of ‘dateTime.QDateTime::date().QDate::toJulianDay()’ from ‘qint64 
{aka long long int}’ to ‘int’ inside { } [-fpermissive]

This is a C++11 build error, but it points to an important problem. In Qt 5, 
QDate has been extended to operate on 64-bit julian days, which means the 
range is much bigger. I don't see a function in the QML compiler to add an 
item of 64-bit in width.

The attached patch is a build fix, but it's not the proper fix (hence the 
warning). I'd like someone who knows this code better to take a look.

With this fix, it compiles and installs.
