Qt4's moc bug patch. 2006-12-16(Sat)

Trolltech has answered this isuue to me and was fixed 2006-12-18's snapshot. So, if you can upgrade it, it should be no problem. (I currently has not time to check that.)

The new Qt4's moc uses static_cast, reinterpret_cast, and const_cast instead of C style cast by Qt3's moc. I think this is an improvement. However, the code src/tools/moc/generater.cpp did not consider the C++ Digraph, which is (I believe) a pitfall to mock the C++ users. Therefore, the moc is mocked by this ISO/IEC 9899-1999, Programming Languages - C standard.
