[Interest] Compiler Error from moc_MainWindow.cpp

[Karl Ruetz]

For your particular case, you should be able to just us a "#undef
Bool" after the #include <Xlib.h> line. 

Or, if you use Xlib.h in many
modules, you can create your own mitchsXlib.h and put this in there.


Or, you could grep the Qt4 sources for Xlib.h and see how they did it.

to start chopping away at X11 header files.
