Boost.Signals и Qt4

Использую библиотечку astxx, которая использует Boost.Signals, использую в программе на Qt, сразу словил ошибку компиляции:

g++ -c -m64 -pipe -g -Wall -W -D_REENTRANT -DQT_CORE_LIB -DQT_SHARED -I/usr/share/qt/mkspecs/linux-g++-64 -I../queue-test -I/usr/include/QtCore -I/usr/include -I. -I../queue-test -I. -o main.o ../queue-test/main.cpp

Описания способов решения нашел тут:

http://www.boost.org/doc/libs/1_45_0/doc/html/signals/s04.html

~~Пока же, временно, определил макрос:~~

#define BOOST_SIGNALS_NAMESPACE boost_signals

Upd:

В .pro файле добавил:

CONFIG += no_keywords

После чего такие конструкции перестанут компилироваться:

signals:
private slots:
public slots:

Заменить на:

Q_SIGNALS:
private Q_SLOTS:
public Q_SLOTS:
