[Interest] qtsingleapplication problem compiling

I just started using qtsingleapplication from qt solutions. I see that recently Christian Dähn responded to a reported problem in this component, so I'm hopeful that there is still interest in improving it. But I don't see a clear way to file bugs- is there a way?

We compile with QT_NO_CAST_FROM_BYTEARRAY and QT_NO_CAST_FROM_ASCII defined. The file qtlocalpeer.cpp gives a couple of compile errors with those definitions:

 /qtbuild/install/macosx/include/QtCore/qstring.h: In constructor 'QtLocalPeer::QtLocalPeer(QObject*, const QString&)':
/qtbuild/install/macosx/include/QtCore/qstring.h:597: error: 'QString::QString(const char*)' is private
../IgorSrc7/qtsingleapplication/src/qtlocalpeer.cpp:80: error: within this context
/qtbuild/install/macosx/include/QtCore/qbytearray.h: In member function 'void QtLocalPeer::receiveConnection()':
/qtbuild/install/macosx/include/QtCore/qbytearray.h:383: error: 'QByteArray::operator QNoImplicitBoolCast() const' is private
../IgorSrc7/qtsingleapplication/src/qtlocalpeer.cpp:197: error: within this context
../IgorSrc7/qtsingleapplication/src/qtlocalpeer.cpp:197: error: invalid conversion from 'QNoImplicitBoolCast' to 'const char*'
../IgorSrc7/qtsingleapplication/src/qtlocalpeer.cpp:197: error:   initializing argument 1 of 'static QString QString::fromUtf8(const char*, int)'

It's easy to fix, as far as I can see:

Line 80:

Line 197:
 	QString message(QString::fromUtf8(uMsgBuf));

and I don't think that will cause problems when those macros are NOT defined.
