[webkit-dev] webkit qt compile error

[Arun Patole]

I have built and installed qt 4.4.3 on my machine and could see these
variables in qglobal.h:

/usr/local/Trolltech/QtEmbedded-4.4.3-arm/include$ grep -r  grep -r
QT_PREPEND_NAMESPACE *

Qt/qglobal.h:# define QT_PREPEND_NAMESPACE(name) ::name
Qt/qglobal.h:# define QT_PREPEND_NAMESPACE(name) ::QT_NAMESPACE::name
QtCore/qglobal.h:# define QT_PREPEND_NAMESPACE(name) ::name
QtCore/qglobal.h:# define QT_PREPEND_NAMESPACE(name) ::QT_NAMESPACE::name

But I couldn't see them defined in qglobal.h which comes with the libqt4-dev
package. Might be something newly added in Qt.
