If -no-xshape option is set, the compilation of Qt fails on Linux

If -no-xshape option is set in the configure, the compilation of Qt fails with:

kernel/qdnd_x11.cpp: In function ‘bool windowInteractsWithPosition(const QPoint&, Window, int)’:
kernel/qdnd_x11.cpp:1410:116: error: ‘XShapeGetRectangles’ was not declared in this scope
kernel/qdnd_x11.cpp: In function ‘Window findRealWindow(const QPoint&, Window, int)’:
kernel/qdnd_x11.cpp:1450:79: error: ‘ShapeInput’ was not declared in this scope
kernel/qdnd_x11.cpp:1450:130: error: ‘ShapeBounding’ was not declared in this scope

It seems that there is no check for the ShapeBounding in the qt/src/gui/kernel/qdnd_x11.cpp in:
static
bool windowInteractsWithPosition(const QPoint & pos, Window w, int shapeType)
